  • My xcode mapview wont work when combined with webview

    - by user1715702
    I have a small problem with my mapview. When combining the mapview code with the code for webview, the app does not zoom in on my position correctly (just gives me a world overview where i´m supposed to be somewhere in California - wish I was). And it doesn´t show the pin that I have placed on a specific location. These things works perfectly fine, as long as the code does not contain anything concerning webview. Below you´ll find the code. If someone can help me to solve this, I would be som thankful! ViewController.h #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #define METERS_PER_MILE 1609.344 @interface ViewController : UIViewController <MKMapViewDelegate>{ BOOL _doneInitialZoom; IBOutlet UIWebView *webView; } @property (weak, nonatomic) IBOutlet MKMapView *_mapView; @property (nonatomic, retain) UIWebView *webView; @end ViewController.m #import "ViewController.h" #import "NewClass.h" @interface ViewController () @end @implementation ViewController @synthesize _mapView; @synthesize webView; - (void)viewDidLoad { [super viewDidLoad]; [_mapView setMapType:MKMapTypeStandard]; [_mapView setZoomEnabled:YES]; [_mapView setScrollEnabled:YES]; MKCoordinateRegion region = { {0.0,0.0} , {0.0,0.0} }; region.center.latitude = 61.097557; region.center.longitude = 12.126545; region.span.latitudeDelta = 0.01f; region.span.longitudeDelta = 0.01f; [_mapView setRegion:region animated:YES]; newClass *ann = [[newClass alloc] init]; ann.title = @"Hjem"; ann.subtitle = @"Her bor jeg"; ann.coordinate = region.center; [_mapView addAnnotation:ann]; NSString *urlAddress = @"http://google.no"; //Create a URL object.

  • MediaElement not showing in custom 3D class

    - by user3271180
    I'm trying to display a videostream in a Viewport3d. When I add the MediaElement via xaml, the video plays without a problem; even when I add the video as ModelVisual3D in the code-behind, the video works. When I abstract the video into a class, however, the video stops appearing. This happens with both web and local video files. I tried compiling with both x86 and 64 bit. Any way to fix this behaviour? Why is this happening? I have the following viewport: <Viewport3D> <!-- Camera --> <Viewport3D.Camera> <PerspectiveCamera Position="0,0,100" LookDirection="0,0,-1" UpDirection="0,1,0" /> </Viewport3D.Camera> <!-- Light --> <ModelVisual3D> <ModelVisual3D.Content> <AmbientLight Color="White" /> </ModelVisual3D.Content> </ModelVisual3D> <!-- this doesn't work --> <mediaElementTest:VideoControl /> <!-- but this does? --> <!--<ModelVisual3D> <ModelVisual3D.Content> <GeometryModel3D> <GeometryModel3D.Geometry> <MeshGeometry3D Positions="-100,-100,0 100,-100,0 100,100,0 -100,100,0" TextureCoordinates="0,1 1,1 1,0 0,0" TriangleIndices="0 1 2 0 2 3" /> </GeometryModel3D.Geometry> <GeometryModel3D.Material> <DiffuseMaterial> <DiffuseMaterial.Brush> <VisualBrush> <VisualBrush.Visual> <MediaElement Source="http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4" /> </VisualBrush.Visual> </VisualBrush> </DiffuseMaterial.Brush> </DiffuseMaterial> </GeometryModel3D.Material> </GeometryModel3D> </ModelVisual3D.Content> </ModelVisual3D>--> </Viewport3D> VideoControl.xaml <UIElement3D x:Class="MediaElementTest.VideoControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"/> VideoControl.xaml.cs public partial class VideoControl { public VideoControl() { InitializeComponent(); Visual3DModel = CreateModel(); } private GeometryModel3D CreateModel() { return new GeometryModel3D { Geometry = new MeshGeometry3D { Positions = new Point3DCollection { new Point3D(-100, -100, 0), new Point3D(100, -100, 0), new Point3D(100, 100, 0), new Point3D(-100, 100, 0) }, TextureCoordinates = new PointCollection { new Point(0, 1), new Point(1, 1), new Point(1, 0), new Point(0, 0) }, TriangleIndices = new Int32Collection { 0, 1, 2, 0, 2, 3 } }, Material = new DiffuseMaterial(new VisualBrush(new MediaElement { Source = new Uri("http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4", UriKind.RelativeOrAbsolute) })) }; } }

  • texture colours opengl

    - by user1324894
    Hi I am making a simple 2D game in c++ and for the map I am doing texture mapping by using tiles and assigning textures to those tiles. However, when I run the programme the textures become black and white when I want them to be the colour they are in the .png image.

  • Can't display Tool Tips in VC++6.0

    - by Paul
    I'm missing something fundamental, and probably both simple and obvious. My issue: I have a view (CPlaybackView, derived from CView). The view displays a bunch of objects derived from CRectTracker (CMpRectTracker). These objects each contain a floating point member. I want to display that floating point member when the mouse hovers over the CMpRectTracker. The handler method is never executed, although I can trace through OnIntitialUpdate, PreTranslateMessage, and OnMouseMove. This is in Visual C++ v. 6.0. Here's what I've done to try to accomplish this: 1. In the view's header file: public: BOOL OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult); private: CToolTipCtrl m_ToolTip; CMpRectTracker *m_pCurrentRectTracker;//Derived from CRectTracker 2. In the view's implementation file: a. In Message Map: ON_NOTIFY_EX(TTN_NEEDTEXT,0,OnToolTipNeedText) b. In CPlaybackView::OnInitialUpdate: if (m_ToolTip.Create(this, TTS_ALWAYSTIP) && m_ToolTip.AddTool(this)) { m_ToolTip.SendMessage(TTM_SETMAXTIPWIDTH, 0, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_AUTOPOP, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_INITIAL, 200); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_RESHOW, 200); } else { TRACE("Error in creating ToolTip"); } this->EnableToolTips(); c. In CPlaybackView::OnMouseMove: if (::IsWindow(m_ToolTip.m_hWnd)) { m_pCurrentRectTracker = NULL; m_ToolTip.Activate(FALSE); if(m_rtMilepostRect.HitTest(point) >= 0) { POSITION pos = pDoc->m_rtMilepostList.GetHeadPosition(); while(pos) { CMpRectTracker tracker = pDoc->m_rtMilepostList.GetNext(pos); if(tracker.HitTest(point) >= 0) { m_pCurrentRectTracker = &tracker; m_ToolTip.Activate(TRUE); break; } } } } d. In CPlaybackView::PreTranslateMessage: if (::IsWindow(m_ToolTip.m_hWnd) && pMsg->hwnd == m_hWnd) { switch(pMsg->message) { case WM_LBUTTONDOWN: case WM_MOUSEMOVE: case WM_LBUTTONUP: case WM_RBUTTONDOWN: case WM_MBUTTONDOWN: case WM_RBUTTONUP: case WM_MBUTTONUP: m_ToolTip.RelayEvent(pMsg); break; } } e. Finally, the handler method: BOOL CPlaybackView::OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult) { BOOL bHandledNotify = FALSE; CPoint CursorPos; VERIFY(::GetCursorPos(&CursorPos)); ScreenToClient(&CursorPos); CRect ClientRect; GetClientRect(ClientRect); // Make certain that the cursor is in the client rect, because the // mainframe also wants these messages to provide tooltips for the // toolbar. if (ClientRect.PtInRect(CursorPos)) { TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR; CString str; str.Format("%f", m_pCurrentRectTracker->GetMilepost()); ASSERT(str.GetLength() < sizeof(pTTT->szText)); ::strcpy(pTTT->szText, str); bHandledNotify = TRUE; } return bHandledNotify; }

  • Removing google mail markers with jquery after getting them from xml

    - by sebastian
    Hi there, I'm trying to create a page that contains a google map. The map is filled with markers from an xml file. I just can't figure out how to remove "old" markers, that don't match the latest user input. At the moment my js stops after the very first xml item. The clearList.push(marker); is supposed to put the generated marker away for later usage. When the user hits the search button I want all markers to be gone and use clearMarkers();. Maybe someone here can help Sebastian Here is my JavaScript: $(document).ready(function() { $("#map").css({height: 650}); var clearList = []; var myLatLng = new google.maps.LatLng(52.518143, 13.372879); MYMAP.init('#map', myLatLng, 11); $("#showmarkers").click(function(e){ clearMarkers(); MYMAP.placeMarkers('markers.xml'); }); }); function clearMarkers() { $(clearList).each(function () { this.setmap(null); }); clearList = []; } var MYMAP = { map: null, bounds: null } MYMAP.init = function(selector, latLng, zoom) { var myOptions = { zoom:zoom, center: latLng, mapTypeId: google.maps.MapTypeId.HYBRID } this.map = new google.maps.Map($(selector)[0], myOptions); this.bounds = new google.maps.LatLngBounds(); } MYMAP.placeMarkers = function(filename) { $.get(filename, function(xml){ $(xml).find("marker").each(function(){ // read values from xml for searching var platzart = $(this).find('platzart').text(); var ort = $(this).find('ort').text(); var open = $(this).find('open').text(); if (platzart =="Kunstrasen" && $('#kunstrasen').attr('checked') || platzart =="Rasen" && $('#rasen').attr('checked') || platzart =="Tartan" && $('#tartan').attr('checked') || platzart =="Boltzplatz" && $('#boltzplatz').attr('checked') ){ // read values from xml for additional info var name = $(this).find('name').text(); var plz = $(this).find('plz').text(); var note = $(this).find('note').text(); var adress = $(this).find('adress').text(); // create a new LatLng point for the marker var lat = $(this).find('lat').text(); var lng = $(this).find('lng').text(); var point = new google.maps.LatLng(parseFloat(lat),parseFloat(lng)); // extend the bounds to include the new point MYMAP.bounds.extend(point); // create new marker var marker = new google.maps.Marker({ position: point, map: MYMAP.map }); clearList.push(marker); // add onclick overlay var infoWindow = new google.maps.InfoWindow(); var html='<strong>'+name+'</strong.><br />'+platzart; google.maps.event.addListener(marker, 'click', function() { infoWindow.setContent(html); infoWindow.open(MYMAP.map, marker); }); } MYMAP.map.fitBounds(MYMAP.bounds); }); }); } Thanks in advance

  • BB Code Parser (in formatting phase) with jQuery jammed due to messed up loops most likely

    - by Oskar
    Greetings everyone, I'm making a BB Code Parser but I'm stuck on the JavaScript front. I'm using jQuery and the caret library for noting selections in a text field. When someone selects a piece of text a div with formatting options will appear. I have two issues. Issue 1. How can I make this work for multiple textfields? I'm drawing a blank as it currently will detect the textfield correctly until it enters the $("#BBtoolBox a").mousedown(function() { } loop. After entering it will start listing one field after another in a random pattern in my eyes. !!! MAIN Issue 2. I'm guessing this is the main reason for issue 1 as well. When I press a formatting option it will work on the first action but not the ones afterwards. It keeps duplicating the variable parsed. (if I only keep to one field it will never print in the second) Issue 3 If you find anything especially ugly in the code, please tell me how to improve myself. I appriciate all help I can get. Thanks in advance $(document).ready(function() { BBCP(); }); function BBCP(el) { if(!el) { el = "textarea"; } // Stores the cursor position of selection start $(el).mousedown(function(e) { coordX = e.pageX; coordY = e.pageY; // Event of selection finish by using keyboard }).keyup(function() { BBtoolBox(this, coordX, coordY); // Event of selection finish by using mouse }).mouseup(function() { BBtoolBox(this, coordX, coordY); // Event of field unfocus }).blur(function() { $("#BBtoolBox").hide(); }); } function BBtoolBox(el, coordX, coordY) { // Variable containing the selected text by Caret selection = $(el).caret().text; // Ignore the request if no text is selected if(selection.length == 0) { $("#BBtoolBox").hide(); return; } // Print the toolbox if(!document.getElementById("BBtoolBox")) { $(el).before("<div id=\"BBtoolBox\" style=\"left: "+ ( coordX + 5 ) +"px; top: "+ ( coordY - 30 ) +"px;\"></div>"); // List of actions $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_bold.png\" alt=\"B\" title=\"Bold\" /></a>"); $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_italic.png\" alt=\"I\" title=\"Italic\" /></a>"); } else { $("#BBtoolBox").css({'left': (coordX + 3) +'px', 'top': (coordY - 30) +'px'}).show(); } // Parse the text according to the action requsted $("#BBtoolBox a").mousedown(function() { switch($(this).children(":first").attr("alt")) { case "B": // bold parsed = "[b]"+ selection +"[/b]"; break; case "I": // italic parsed = "[i]"+ selection +"[/i]"; break; } // Changes the field value by replacing the selection with the variable parsed $(el).val($(el).caret().replace(parsed)); $("#BBtoolBox").hide(); return false; }); }

  • How to get data from struts2 action with jQuery?

    - by Rafa Romero
    I have an Struts2 Web with GoogleMaps. I want to load a list of markers which are saved in a SQL DDBB. To do this, I tried with jQuery and Ajax. Here you are the code: loadMarkers.java public class loadMarkers extends ActionSupport implements ServletRequestAware,ServletResponseAware{ //Variables de sesion/cookie FunctionClass ses; protected HttpServletResponse servletResponse; protected HttpServletRequest servletRequest; private String userID=""; //Variables del marker private List<marker> markersList = new ArrayList<marker>(); public String execute() throws Exception{ FunctionClass friends = new FunctionClass(); //Leemos de la cookie for(Cookie c : servletRequest.getCookies()) { if (c.getName().equals("userID")) userID = (c.getValue()); } System.out.println("en el loadMarkers"); connectionBBDD con = new connectionBBDD(); markersList = con.loadMarkers(userID); return SUCCESS; } I want to use the markerList array in Javascript, to create the markers. This is the struts.xml file: <package name="jsonActions" namespace="/test" extends="json-default"> <action name="LoadMarkers" class="web.localizadroid.maps.loadMarkers"> <interceptor-ref name="basicStack"/> <result type="json"> <param name="root">markersList</param> </result> </action> </package> And here you are the Javascript (jQuery) code: function loadMarkersJ(){ alert("dentro"); $.ajax({ type : "post", url : "LoadMarkers", dataType: "json", success : function(data) { alert(data); var image = new google.maps.MarkerImage ('http://i53.tinypic.com/ettquh.png'); var jSon_Object = eval("(" + data + ")"); //For para analizar los datos (Json) obtenidos de la BBDD for (x = 0; x < jSon_Object.length; x++) { var markersArray = []; var myLatlng = new google.maps.LatLng(jSon_Object[x].lat, jSon_Object[x].lon); markerLoaded = new google.maps.Marker( { position : myLatlng, map : map, icon: image, title: "NOMBRE: " + jSon_Object[x].tarjetName + "\n" + "ANOTACIONES: " + jSon_Object[x].anotaciones + "\n" + "TIME: " + jSon_Object[x].time }); markersArray.push(markerLoaded); if (markersArray) { for (i in markersArray) { alert("entro en forColocaMarkers"); if (markersArray[i].getAnimation() != null) { markersArray[i].setAnimation(null); } else { markersArray[i].setAnimation(google.maps.Animation.BOUNCE); } markersArray[i].setMap(map); } } } } }); } From success : function(data) { to the end, is JavaScript code to create de markers, and this it's OK. The problem is whith ajax, because I don't get to obtain markerList Array by jSon data return...I think that the problem is in the url attribute from $.ajax...I tried loadMarkers.action and loadMarkers, but nothing happens. When I execute the web, only prints the alert alert("dentro"), the alert alert(data) never has been printed. I have forgotten to add the code where I call the Javascript function (loadMarkersJ). Here you are: <p><s:a action="LoadMarkers.action" namespace="/test" onclick="loadMarkersJ(this)">Cargar Marcadores S</s:a></p> Somebody can help me please?

  • Strange behaviour when simply adding strings in Lazarus - FreePascal

    - by linkcharger
    The program has several "encryption" algorithms. This one should blockwise reverse the input. "He|ll|o " becomes "o |ll|He" (block length of 2). I add two strings, in this case appending the result string to the current "block" string and making that the result. When I add the result first and then the block it works fine and gives me back the original string. But when i try to reverse the order it just gives me the the last "block". Several other functions that are used for "rotation" are above. //amount of blocks function amBl(i1:integer;i2:integer):integer; begin if (i1 mod i2) <> 0 then result := (i1 div i2) else result := (i1 div i2) - 1; end; //calculation of block length function calcBl(keyStr:string):integer; var i:integer; begin result := 0; for i := 1 to Length(keyStr) do begin result := (result + ord(keyStr[i])) mod 5; result := result + 2; end; end; //desperate try to add strings function append(s1,s2:string):string; begin insert(s2,s1,Length(s1)+1); result := s1; end; function rotation(inStr,keyStr:string):string; var //array of chars -> string block,temp:string; //position in block variable posB:integer; //block length and block count variable bl, bc:integer; //null character as placeholder n : ansiChar; begin //calculating block length 2..6 bl := calcBl(keyStr); setLength(block,bl); result := ''; temp := ''; {n := #00;} for bc := 0 to amBl(Length(inStr),bl) do begin //filling block with chars starting from back of virtual block (in inStr) for posB := 1 to bl do begin block[posB] := inStr[bc * bl + posB]; {if inStr[bc * bl + posB] = ' ' then block[posB] := n;} end; //adding the block in front of the existing result string temp := result; result := block + temp; //result := append(block,temp); //result := concat(block,temp); end; end; (full code http://pastebin.com/6Uarerhk) After all the loops "result" has the right value, but in the last step (between "result := block + temp" and the "end;" of the function) "block" replaces the content of "result" with itself completely, it doesn't add result at the end anymore. And as you can see I even used a temp variable to try to work around that.. doesnt change anything though.

  • Lockless queue implementation ends up having a loop under stress

    - by Fozi
    I have lockless queues written in C in form of a linked list that contains requests from several threads posted to and handled in a single thread. After a few hours of stress I end up having the last request's next pointer pointing to itself, which creates an endless loop and locks up the handling thread. The application runs (and fails) on both Linux and Windows. I'm debugging on Windows, where my COMPARE_EXCHANGE_PTR maps to InterlockedCompareExchangePointer. This is the code that pushes a request to the head of the list, and is called from several threads: void push_request(struct request * volatile * root, struct request * request) { assert(request); do { request->next = *root; } while(COMPARE_EXCHANGE_PTR(root, request, request->next) != request->next); } This is the code that gets a request from the end of the list, and is only called by a single thread that is handling them: struct request * pop_request(struct request * volatile * root) { struct request * volatile * p; struct request * request; do { p = root; while(*p && (*p)->next) p = &(*p)->next; // <- loops here request = *p; } while(COMPARE_EXCHANGE_PTR(p, NULL, request) != request); assert(request->next == NULL); return request; } Note that I'm not using a tail pointer because I wanted to avoid the complication of having to deal with the tail pointer in push_request. However I suspect that the problem might be in the way I find the end of the list. There are several places that push a request into the queue, but they all look generaly like this: // device->requests is defined as struct request * volatile requests; struct request * request = malloc(sizeof(struct request)); if(request) { // fill out request fields push_request(&device->requests, request); sem_post(device->request_sem); } The code that handles the request is doing more than that, but in essence does this in a loop: if(sem_wait_timeout(device->request_sem, timeout) == sem_success) { struct request * request = pop_request(&device->requests); // handle request free(request); } I also just added a function that is checking the list for duplicates before and after each operation, but I'm afraid that this check will change the timing so that I will never encounter the point where it fails. (I'm waiting for it to break as I'm writing this.) When I break the hanging program the handler thread loops in pop_request at the marked position. I have a valid list of one or more requests and the last one's next pointer points to itself. The request queues are usually short, I've never seen more then 10, and only 1 and 3 the two times I could take a look at this failure in the debugger. I thought this through as much as I could and I came to the conclusion that I should never be able to end up with a loop in my list unless I push the same request twice. I'm quite sure that this never happens. I'm also fairly sure (although not completely) that it's not the ABA problem. I know that I might pop more than one request at the same time, but I believe this is irrelevant here, and I've never seen it happening. (I'll fix this as well) I thought long and hard about how I can break my function, but I don't see a way to end up with a loop. So the question is: Can someone see a way how this can break? Can someone prove that this can not? Eventually I will solve this (maybe by using a tail pointer or some other solution - locking would be a problem because the threads that post should not be locked, I do have a RW lock at hand though) but I would like to make sure that changing the list actually solves my problem (as opposed to makes it just less likely because of different timing).

  • Does anyone know how to layout a JToolBar that does't move or re-size any components placed in it?

    - by S1.Mac
    Can anyone help with this problem i'm trying to create a JToolBar and I want all its components to be fixed in size and position. I'v tried a few different layout managers but they all center and/or re-size the components when the frame its in is re-sized. here is an example using GridbagLayout, I have also used the default layout manager using the toolbar.add( component ) method but the result is the same : ' import java.awt.BorderLayout; import java.awt.Component; import java.awt.Dimension; import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import javax.swing.*; public class ToolBarTest extends JFrame { private JToolBar toolbar; private JPanel mainPanel; private JPanel toolBarPanel; private JButton aButton; private JCheckBox aCheckBox; private JList aList; private Box toolbarBox; private GridBagConstraints toolbarConstraints; private GridBagLayout toolbarLayout; private JLabel shapeLabel; private JComboBox<ImageIcon> shapeChooser; private JLabel colorLabel; private JComboBox colorChooser; private String colorNames[] = { "Black" , "Blue", "Cyan", "Dark Gray", "Gray", "Green", "Light Gray", "Magenta", "Orange", "Pink", "Red", "White", "Yellow", "Custom" }; private String shapeNames[] = { "Line", "Oval", "Rectangle", "3D Rectangle","Paint Brush", "Rounded Rectangle" }; public ToolBarTest() { setLayout( new BorderLayout() ); setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); setSize( 500, 500 ); add( createToolBar(), BorderLayout.PAGE_START ); setVisible( true ); } public void addToToolbar( Component component, int row, int column ) { toolbarConstraints.gridx = column; toolbarConstraints.gridy = row; toolbarConstraints.anchor = GridBagConstraints.WEST; toolbarConstraints.fill = GridBagConstraints.NONE; toolbarConstraints.weightx = 0; toolbarConstraints.weighty = 0; toolbarConstraints.gridwidth = 1; toolbarConstraints.gridheight = 1; toolbarLayout.setConstraints( component, toolbarConstraints ); toolbar.add( component ); }// end addToToolbar public final JToolBar createToolBar() { toolbarLayout = new GridBagLayout(); toolbarConstraints = new GridBagConstraints(); // create the tool bar which holds the items to draw toolbar = new JToolBar(); toolbar.setBorderPainted(true); toolbar.setLayout( toolbarLayout ); toolbar.setFloatable( true ); shapeLabel = new JLabel( "Shapes: " ); addToToolbar( shapeLabel, 0, 1 ); String iconNames[] = { "PaintImages/Line.jpg", "PaintImages/Oval.jpg", "PaintImages/Rect.jpg", "PaintImages/3DRect.jpg","PaintImages/PaintBrush.jpg", "PaintImages/RoundRect.jpg"}; ImageIcon shapeIcons[] = new ImageIcon[ shapeNames.length ]; // create image icons for( int shapeButton = 0; shapeButton < shapeNames.length; shapeButton++ ) { shapeIcons[ shapeButton ] = new ImageIcon( iconNames[ shapeButton ] ); }// end for shapeChooser = new JComboBox< ImageIcon >( shapeIcons ); shapeChooser.setSize( new Dimension( 50, 20 )); shapeChooser.setPrototypeDisplayValue( shapeIcons[ 0 ] ); shapeChooser.setSelectedIndex( 0 ); addToToolbar( shapeChooser, 0, 2 ); colorLabel = new JLabel( "Colors: " ); addToToolbar( colorLabel, 0, 3 ); colorChooser = new JComboBox( colorNames ); addToToolbar( colorChooser, 0, 4 ); return toolbar; }// end createToolBar public static void main( String args[] ) { new ToolBarTest(); }// end main }// end class ToolBarTest'

  • What is the best free or low-cost Java reporting library (e.g. BIRT, JasperReports, etc.) for making

    - by Max3000
    I want to print, email and write to PDF very simple reports. The reports are basically a list of items, divided in various sections/columns. The sections are not necessarily identical. Think newspaper. I just wasted a solid 2 days of work trying to make this kind of reports using JasperReports. I find that Jasper is great for outputing "normalized" data. The kind that would come out of a database for instance, each row neatly describing an item and each item printed on a line. I'm simplifying a bit but that's the idea. However, given what I want to do I always ended up completely lost. Data not being displayed for no apparent reason, columns of texts never the correct size, column positioning always ending up incorrect, pagination not sanely possible (I was never able to figure it out; the FAQ gives an obscure workaround), etc. I came to the conclusion that Jasper is really not built to make the kind of reports I want. Am I missing something? I'm ready to pay for a tool, as long as the price is reasonable. By reasonable I mean a few $100s. Thanks. EDIT: To answer cetus, here is more information about the report I made in Jasper. What I want is something like this: text text text text ------------------- text | text text |---------- text | text text | text --------| text text |---------- text | text What I made in jasper is this: (detail band) subreport | subreport ------------------------------------ subreport | subreport ------------------------------------ subreport | subreport The subreports are all the same actual report. This report has one field (called "field") and basically just prints this field in a detail band. Hence, running a single subreport simply lists all items from the datasource. The datasource itself is a simple custom JRDatasource containing a collection of strings in the field "field". The datasource iterates over the collection until there are no more strings. Each subreport has its own datasource. I tried many different variations of the above, with all sorts of different properties for the report, subreports, etc. IMO, this is fairly simple stuff. However, the problems I encounter are as follows: Subreports starting from the 3rd don't show up when their position type is 'float'. They do show up when they have 'fix relative to top'. However, I don't want to do this because the first two subreports can be of any length. I can't make each subreport to stretch according to its own length. Instead, they either don't stretch at all (which is not desirable because they have different lenghts) or they stretch according to the longest subreport. This makes a weird layout for sure. Pagination doesn't happen. If some subreports fall outside the page, they simple don't show. One alternative is to increase the 'page height' considerably and the 'detail band height' accordingly. However, in this case it is not really possibly to know the total height in advance. So I'm stuck with calculating/guessing it myself, before the report is even generated. More importantly, long reports end up on one page and this is not acceptable (the printout text is too small, it's ugly/non-professional to have different reports with different PDF page lengths, etc.). BTW, I used iReport so it's possibly limitations of iReport I'm listing here and not of Jasper itself. That's one of the things I'm trying to find out asking this question here. One alternative would be to generate the jrxml myself with just static text but I'm afraid I'll encounter the very same limitations. Anyway, I just generally wasted so much time getting anything done with Jasper that I can't help thinking its not the right tool for the job. (Not to say that Jasper doesn't excel in what it's good at).

With the following block of code I'm doing the plotting : Cluster.prototype.initiate_map_assembling = function() { return $(this.map_canvas_wrapper_class).each(function(index, element) { var canvas = $(element).children(); var latitude = $(canvas).attr('data-latitude'); var longitude = $(canvas).attr('data-longitude'); var coordinates = new google.maps.LatLng(latitude, longitude); var options = { zoom: 9, center: coordinates, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map($(canvas), options); var marker = new google.maps.Marker({ position: coordinates, map: map }); }); }; This way I'm "looping" through all the parent classes of the id I'm trying to append the map to, but the map would only append to the first id. I tried to append it to all of the id's in other ways but with the same results. So what would you suggest me to do to make it work as I would expect it, append the map to each of the id's ?

  • Javascript and Twitter API rate limitation? (Changing variable values in a loop)

    - by Pablo
    Hello, I have adapted an script from an example of http://github.com/remy/twitterlib. It´s a script that makes one query each 10 seconds to my Twitter timeline, to get only the messages that begin with a musical notation. It´s already working, but I don´t know it is the better way to do this... The Twitter API has a rate limit of 150 IP access per hour (queries from the same user). At this time, my Twitter API is blocked at 25 minutes because the 10 seconds frecuency between posts. If I set up a frecuency of 25 seconds between post, I am below the rate limit per hour, but the first 10 posts are shown so slowly. I think this way I can guarantee to be below the Twitter API rate limit and show the first 10 posts at normal speed: For the first 10 posts, I would like to set a frecuency of 5 seconds between queries. For the rest of the posts, I would like to set a frecuency of 25 seconds between queries. I think if making somewhere in the code a loop with the previous sentences, setting the "frecuency" value from 5000 to 25000 after the 10th query (or after 50 seconds, it´s the same), that´s it... Can you help me on modify this code below to make it work? Thank you in advance. var Queue = function (delay, callback) { var q = [], timer = null, processed = {}, empty = null, ignoreRT = twitterlib.filter.format('-"RT @"'); function process() { var item = null; if (q.length) { callback(q.shift()); } else { this.stop(); setTimeout(empty, 5000); } return this; } return { push: function (item) { var green = [], i; if (!(item instanceof Array)) { item = [item]; } if (timer == null && q.length == 0) { this.start(); } for (i = 0; i < item.length; i++) { if (!processed[item[i].id] && twitterlib.filter.match(item[i], ignoreRT)) { processed[item[i].id] = true; q.push(item[i]); } } q = q.sort(function (a, b) { return a.id > b.id; }); return this; }, start: function () { if (timer == null) { timer = setInterval(process, delay); } return this; }, stop: function () { clearInterval(timer); timer = null; return this; }, empty: function (fn) { empty = fn; return this; }, q: q, next: process }; }; $.extend($.expr[':'], { below: function (a, i, m) { var y = m[3]; return $(a).offset().top y; } }); function renderTweet(data) { var html = ''; html += ''; html += twitterlib.ify.clean(data.text); html += ''; since_id = data.id; return html; } function passToQueue(data) { if (data.length) { twitterQueue.push(data.reverse()); } } var frecuency = 10000; // The lapse between each new Queue var since_id = 1; var run = function () { twitterlib .timeline('twitteruser', { filter : "'?'", limit: 10 }, passToQueue) }; var twitterQueue = new Queue(frecuency, function (item) { var tweet = $(renderTweet(item)); var tweetClone = tweet.clone().hide().css({ visibility: 'hidden' }).prependTo('#tweets').slideDown(1000); tweet.css({ top: -200, position: 'absolute' }).prependTo('#tweets').animate({ top: 0 }, 1000, function () { tweetClone.css({ visibility: 'visible' }); $(this).remove(); }); $('#tweets p:below(' + window.innerHeight + ')').remove(); }).empty(run); run();

I need to do what is almost exactly like this tutorial... http://androiddevelopement.blogspot.in/2011/06/android-xml-parsing-tutorial-using.html ... however, I can't get the tutorial to work... I also would like to know how I can make the list item clicks so that if I click on "ITEM1-1" it goes to the menu "ITEM2-1" and "ITEM2-2". and if "ITEM1-2" is clicked, then it goes to the menu with "ITEM3-1" and "ITEM3-2"... I am totally a noob at this whole android development thing. So any suggestions would be great!

  • OpenGL texture misaligned on quad

    - by user308226
    I've been having trouble with this for a while now, and I haven't gotten any solutions that work yet. Here is the problem, and the specifics: I am loading a 256x256 uncompressed TGA into a simple OpenGL program that draws a quad on the screen, but when it shows up, it is shifted about two pixels to the left, with the cropped part appearing on the right side. It has been baffling me for the longest time, people have suggested clamping and such, but somehow I think my problem is probably something really simple, but I just can't figure out what it is! Here is a screenshot comparing the TGA (left) and how it appears running in the program (right) for clarity. Also take note that there's a tiny black pixel on the upper right corner, I'm hoping that's related to the same problem. Here's the code for the loader, I'm convinced that my problem lies in the way that I'm loading the texture. Thanks in advance to anyone who can fix my problem. bool TGA::LoadUncompressedTGA(char *filename,ifstream &texturestream) { cout << "G position status:" << texturestream.tellg() << endl; texturestream.read((char*)header, sizeof(header)); //read 6 bytes into the file to get the tga header width = (GLuint)header[1] * 256 + (GLuint)header[0]; //read and calculate width and save height = (GLuint)header[3] * 256 + (GLuint)header[2]; //read and calculate height and save bpp = (GLuint)header[4]; //read bpp and save cout << bpp << endl; if((width <= 0) || (height <= 0) || ((bpp != 24) && (bpp !=32))) //check to make sure the height, width, and bpp are valid { return false; } if(bpp == 24) { type = GL_RGB; } else { type = GL_RGBA; } imagesize = ((bpp/8) * width * height); //determine size in bytes of the image cout << imagesize << endl; imagedata = new GLubyte[imagesize]; //allocate memory for our imagedata variable texturestream.read((char*)imagedata,imagesize); //read according the the size of the image and save into imagedata for(GLuint cswap = 0; cswap < (GLuint)imagesize; cswap += (bpp/8)) //loop through and reverse the tga's BGR format to RGB { imagedata[cswap] ^= imagedata[cswap+2] ^= //1st Byte XOR 3rd Byte XOR 1st Byte XOR 3rd Byte imagedata[cswap] ^= imagedata[cswap+2]; } texturestream.close(); //close ifstream because we're done with it cout << "image loaded" << endl; glGenTextures(1, &texID); // Generate OpenGL texture IDs glBindTexture(GL_TEXTURE_2D, texID); glPixelStorei(GL_UNPACK_ALIGNMENT, 1); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE); glTexImage2D(GL_TEXTURE_2D, 0, type, width, height, 0, type, GL_UNSIGNED_BYTE, imagedata); delete imagedata; return true; } //Public loading function for TGA images.

  • Sidebar with CSS3 transform

    - by Malcoda
    Goal I'm working on a collapsible sidebar using jQuery for animation. I would like to have vertical text on the sidebar that acts as a label and can swap on the animateOut/animateIn effect. Normally I would use an image of the text that I've simply swapped vertically, and switch it out on animation, but with CSS3 transforms I'd like to get it to work instead. Problem The problem I'm facing is that setting the height on my rotated container makes it expand horizontally (as it's rotated 90deg) so that doesn't work. I then tried to set the width (hoping it would expand vertically, acting as height), but that has an odd effect of causing the width of my parent container to expand as well. Fix? Anyone know why this happens and also what the fix/workaround could be without setting max-widths and overflow: hidden? I've got a fairly good understanding of both html elements behavior and css3, but this is stumping me. Live Example Here's a fiddle that demonstrates my problem: Fiddle The collapse-pane class is what I have rotated and contains the span I have my text inside. You'll notice it has a width set, that widens the border, but also affects the parent container. The code: CSS: .right-panel{ position:fixed; right:0; top:0; bottom:0; border:1px solid #ccc; background-color:#efefef; } .collapse-pane{ margin-top:50px; width:30px; border:1px solid #999; cursor:pointer; /* Safari */ -webkit-transform: rotate(-90deg); /* Firefox */ -moz-transform: rotate(-90deg); /* IE */ -ms-transform: rotate(-90deg); /* Opera */ -o-transform: rotate(-90deg); /* Internet Explorer */ filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3); } .collapse-pane span{ padding:5px; } HTML <div class="right-panel"> <div class="collapse-pane"> <span class="expand">Expand</span> </div> <div style="width:0;" class="panel-body"> <div style="display:none;" class="panel-body-inner"> adsfasdfasdf </div> </div> </div> JavaScript (Thought not really relevant) $(document).ready(function(){ var height = $(".right-panel").height(); $(".collapse-pane").css({marginTop: height/2 - 20}); $('.collapse-pane').click(function(){ if($(".collapse-pane span").html() == "Expand"){ $(".panel-body").animate({width:200}, 400); $(".panel-body-inner").fadeIn(500); $(".collapse-pane span").html("Collapse"); }else{ $(".panel-body").animate({width:00}, 400); $(".panel-body-inner").fadeOut(300); $(".collapse-pane span").html("Expand"); } }); }); I hope this was clear... Thanks for any help!

  • Separation of presentation and business logic in PHP

    - by Markus Ossi
    I am programming my first real PHP website and am wondering how to make my code more readable to myself. The reference book I am using is PHP and MySQL Web Development 4th ed. The aforementioned book gives three approaches to separating logic and content: include files function or class API template system I haven't chosen any of these yet, as wrapping my brains around these concepts is taking some time. However, my code has become some hybrid of the first two as I am just copy-pasting away here and modifying as I go. On presentation side, all of my pages have these common elements: header, top navigation, sidebar navigation, content, right sidebar and footer. The function-based examples in the book suggest that I could have these display functions that handle all the presentation example. So, my page code will be like this: display_header(); display_navigation(); display_content(); display_footer(); However, I don't like this because the examples in the book have these print statements with HTML and PHP mixed up like this: echo "<tr bgcolor=\"".$color."\"><td><a href=\"".$url."\">" ... I would rather like to have HTML with some PHP in the middle, not the other way round. I am thinking of making my pages so that at the beginning of my page, I will fetch all the data from database and put it in arrays. I will also get the data for variables. If there are any errors in any of these processes, I will put them into error strings. Then, at the HTML code, I will loop through these arrays using foreach and display the content. In some cases, there will be some variables that will be shown. If there is an error variable that is set, I will display that at the proper position. (As a side note: The thing I do not understand is that in most example code, if some database query or whatnot gives an error, there is always: else echo 'Error'; This baffles me, because when the example code gives an error, it is sometimes echoed out even before the HTML has started...) For people who have used ASP.NET, I have gotten somewhat used to the code-behind files and lblError and I am trying to do something similar here. The thing I haven't figured out is how could I do this "do logic first, then presentation" thing so that I would not have to replicate for example the navigation logic and navigation presentation in all of the pages. Should I do some include files or could I use functions here but a little bit differently? Are there any good articles where these "styles" of separating presentation and logic are explained a little bit more thoroughly. The book I have only has one paragraph about this stuff. What I am thinking is that I am talking about some concepts or ways of doing PHP programming here, but I just don't know the terms for them yet. I know this isn't a straight forward question, I just need some help in organizing my thoughts.
