  • Trouble getting QMainWindow to scroll

    - by random
    A minimal example: class MainWindow(QtGui.QMainWindow): def __init__(self, parent = None): QtGui.QMainWindow.__init__(self, parent) winWidth = 683 winHeight = 784 screen = QtGui.QDesktopWidget().availableGeometry() screenCenterX = (screen.width() - winWidth) / 2 screenCenterY = (screen.height() - winHeight) / 2 self.setGeometry(screenCenterX, screenCenterY, winWidth, winHeight) layout = QtGui.QVBoxLayout() layout.addWidget(FormA()) mainWidget = QtGui.QWidget() mainWidget.setLayout(layout) self.setCentralWidget(mainWidget) FormA is a QFrame with a VBoxLayout that can expand to an arbitrary number of entries. In the code posted above, if the entries in the forms can't fit in the window then the window itself grows. I'd prefer for the window to become scrollable. I've also tried the following... replacing mainWidget = QtGui.QWidget() mainWidget.setLayout(layout) self.setCentralWidget(mainWidget) with mainWidget = QtGui.QScrollArea() mainWidget.setLayout(layout) self.setCentralWidget(mainWidget) results in the forms and entries shrinking if they can't fit in the window. Replacing it with mainWidget = QtGui.QWidget() mainWidget.setLayout(layout) scrollWidget = QtGui.QScrollArea() scrollWidget.setWidget(mainWidget) self.setCentralWidget(scrollWidget) results in the mainwidget (composed of the forms) being scrunched in the top left corner of the window, leaving large blank areas on the right and bottom of it, and still isn't scrollable. I can't set a limit on the size of the window because I wish for it to be resizable. How can I make this window scrollable?

  • Triangulation in 3D Space

    - by w3b_wizzard
    Disclaimer: This is for class, however I'm fresh out of ideas and a nudge in the right direction would be much appreciated. Also, this needs to be implemented in raw C, so no fancy libraries can be used. I have to write a search and rescue simulator for submarines, it has to find a probe that is randomly placed in 3D space in a grid from of the MAX_XYZ (100000). The only tools I'm given are a "ping" which will give the magnitude of the distance between a certain sub and the probe. The goal is to optimize the costs of this entire operation so a brute force attempt, like looking at every single coordinate, won't work. Hence I was thinking triangulation. Now, it makes loads of sense to me, place three subs, each one of them uses their ping to get the distance between them and the probe. Since each sub have a known distance relative to one another, it's easy to build the base of a tetrahedron with them, and the results of the ping will point to a certain coordinate, the problem I'm having is how to figure out the elevation, or the height, of the tetrahedron. So what I have as data is the following: Distances between subs (In vector format) Angles between each subs (very easy to compute) Distance between each sub and the probe (3 segments from the base to the peak) Angles inside each of the outer 3 surfaces of the tetrahedron. I tried finding some sort of relationship with the vertices of the tetrahedron and the relative angles in each of them, however all I found had to deal with tetrahedrons built with equilateral triangles, which isn't much help. I have the impression this can be easily solved with trig but either I'm not seeing it or I need more coffee. Any suggestions would be appreciated!

  • Is there a concise way to map a string to an enum in Objective-C?

    - by zekel
    I have a string I want to parse and return an equivalent enum. I need to use the enum type elsewhere, and I think I like how I'm defining the class. The problem is that I don't know a good way to check the string against the enum values without being redundant about the order of the enums. typedef enum { ZZColorRed, ZZColorGreen, ZZColorBlue, } ZZColorType; - (ZZColorType)parseColor:(NSString *)inputString { // inputString will be @"red", @"green", or @"blue" (trust me) // how can I turn that into ZZColorRed, etc. without // redefining their order like this? NSArray *colors = [NSArray arrayWithObjects:@"red", @"green", @"blue", nil]; return [colors indexOfObject:inputString]; } In Python, I'd probably do something like the following, although to be honest I'm not in love with that either. ## maps url text -> constant string RED_CONSTANT = 1 BLUE_CONSTANT = 2 GREEN_CONSTANT = 3 TYPES = { 'red': RED_CONSTANT, 'green': GREEN_CONSTANT, 'blue': BLUE_CONSTANT, } def parseColor(inputString): return TYPES.get(inputString) ps. I know there are color constants in Cocoa, this is just an example.

  • If either one of both equals

    - by user1620028
    I have start and end dates which are stored in a database in this format: start date= 20121004 //4th October 2012 end date= 20121004 //16th November 2012 so I can use date format: $date = date("Ymd"); // returns: 20121004 to determine when to display and not display to repopulate my update input boxes I use: $start=(str_split($stdate,4));// START DATE: splits stored date into 2x4 ie: 20121209 = 2012 1209 $syr = $start[0];// re first half ie: 2012 which is the year $start2 = $start[1];//re second half ie: 1209 $start3=(str_split($start2,2));// splits second half date into 2x2 ie: 1209 = 12 09 $smth = $start3[0]; // first half = month ie: 12 $sday = $start3[1]; // second half = day ie: 09 $expiry=(str_split($exdate,4)); ///SAME AGAIN FOR EXPIRY DATE ... $xyr = $expiry[0]; $expiry2 = $expiry[1]; $expiry3=(str_split($expiry2,2)); $xmth = $expiry3[0]; $xday = $expiry3[1]; which works fine but I need to repopulate the input boxes for the month showing the date in the database like this <option value="01">January</option`> using if ($smth==01):$month='January'; endif; if ($xmth==01):$month='January'; endif; // if the start and/or expiry month number = 01 display $month as January if ($smth==02):$smonth='February'; endif; if ($xmth==02):$smonth='February'; endif; if ($smth==03):$month='March'; endif; <select name="stmonth" class="input"> <option value="<?=$smth?>"><?=$month?></option> ... </select> is there an easier way to display IF EITHER ONE EQUALS rather than having to write the same line twice once for each $smth AND $xmth ? re: if ($smth **and or** $xmth ==01):$month='January'; endif;

  • How to fetch the value of selected checkbox inside a checkboxList?

    - by Starx
    I want to know the selected value of the markup below. So that I can disabled a textbox, if one of the checkbox is selected. <asp:CheckBoxList ID="ChkTest" runat="server" RepeatDirection="Horizontal" CssClass="toggleYesNo"> <asp:ListItem Value="1">Yes</asp:ListItem> <asp:ListItem Value="0">No</asp:ListItem> </asp:CheckBoxList> I tried using this function it doesnot seem to work $(document).ready(function() { $("#<%=ChkTest.ClientID %>").click(function() { value = $(this).val(); if(value=='1') { $('#atextbox').attr('disabled',''); } else { $('#atextbox').attr('disabled','disabled'); } }); }); I also track the output HTML but the id the CheckBoxList the assigned to a table instead. UPDATED <table id="ChkTest" class="toggleYesNo" border="0"> <tr> <td><input id="ChkTest_0" type="checkbox" name="ChkTest$0" /><label for="ChkTest_0">Yes</label></td><td><input id="ChkTest_1" type="checkbox" name="ChkTest$1" /><label for="ChkTest_1">No</label></td> </tr> </table>

  • How to iterate & retrieve values from NSArray of NSArrays of NSDictionaries

    - by chinjazz
    I'm stumpped on how iterate and get values for an Array of Arrays of NSDictionaries (different classes/entities). Here's what I'm currently doing: 1) Constructing two separate arrays of NSDictionaries (different entities) 2) Combining both arrays with: NSMutableArray *combinedArrayofDicts = [[NSMutableArray alloc] initWithObjects: sizesArrayOfDicts, wishListArrayOfDicts , nil]; 3) Then archive combinedArrayofDicts : NSData *dataToSend = [NSKeyedArchiver archivedDataWithRootObject:combinedArrayofDicts]; 4) Transmit over GameKit [self.session sendDataToAllPiers:dataToSend withDataMode: GKSendDataReliable error:nil]; 5) How would I manage traversing thru this array on the receiving end? I want to fetch values by for each class which is key'ed by classname: Here's how it looks via NSLog (2 Sizes Dicts, and 1 Wishlist Dict) Printing description of receivedArray: <__NSArrayM 0xbc65eb0>( <__NSArrayM 0xbc651f0>( { classname = Sizes; displayOrder = 0; share = 1; sizeType = Neck; value = "13\" or 33 (cm)"; }, { classname = Sizes; displayOrder = 0; share = 1; sizeType = Sleeve; value = "34\" or 86 (cm)"; } ) , <__NSArrayM 0xbc65e80>( { classname = Wishlist; detail = ""; displayOrder = 0; imageString = ""; latitude = "30.33216666666667"; link = "http://maps.google.com/maps?q=loc:30.332,-81.41"; longitude = "-81.40949999999999"; name = bass; share = 1; store = ""; } ) ) (lldb) In my for loop I'm issuing this: NSString *value = [dict objectForKey:@"classname"]; and get an exception: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM objectForKey:]: unrecognized selector sent to instance 0xbc651f0' Is this frowned upon as far as mixing object types in arrays of arrays?

  • AngularJS Templates run twice

    - by Curt
    I'm working on an AngularJS web app with Twitter Bootstrap. The templates run twice. I don't know why they do this. Below is some of the code in the index.html file: <html data-ng-app="app" ng-controller="AppCtrl"> <div class="container ng-view" data-ng-view></div> ... <script> (function (angular) { "use strict"; // jshint ;_; // http://coenraets.org/blog/2012/02/sample-application-with-angular-js/ angular.module('app', ['filters', 'angular', 'currency']) .config(function($routeProvider) { var _view_ = 'view/'; $routeProvider. when('/app', {templateUrl:_view_+'app/index.html', }). when('/account/settings', {templateUrl:_view_+'app/settings.html', }). when('/profile/:profile_ID', {templateUrl:_view_+'app/profile.html', controller:ProfilePageCtrl}). when('/discuss', {templateUrl:_view_+'discuss/discuss.html', controller:DiscussCtrl}). when('/', {templateUrl:_view_+'page/home.html' }). when('/:page', {templateUrl:_view_+'page.html', controller:PageCtrl}). otherwise({redirectTo:'/'}); }) ... Can anybody provide suggestions? Are the templates supposed to run twice? 2012-12-04 Update: I found out that the templates are running twice, not the controller.

  • How to check if a thread is busy in C#?

    - by Sam
    I have a Windows Forms UI running on a thread, Thread1. I have another thread, Thread2, that gets tons of data via external events that needs to update the Windows UI. (It actually updates multiple UI threads.) I have a third thread, Thread3, that I use as a buffer thread between Thread1 and Thread2 so that Thread2 can continue to update other threads (via the same method). My buffer thread, Thread3, looks like this: public class ThreadBuffer { public ThreadBuffer(frmUI form, CustomArgs e) { form.Invoke((MethodInvoker)delegate { form.UpdateUI(e); }); } } What I would like to do is for my ThreadBuffer to check whether my form is currently busy doing previous updates. If it is, I'd like for it to wait until it frees up and then invoke the UpdateUI(e). I was thinking about either: a) //PseudoCode while(form==busy) { // Do nothing; } form.Invoke((MethodInvoker)delegate { form.UpdateUI(e); }); How would I check the form==busy? Also, I am not sure that this is a good approach. b) Create an event in form1 that will notify the ThreadBuffer that it is ready to process. // psuedocode List<CustomArgs> elist = new List<CustomArgs>(); public ThreadBuffer(frmUI form, CustomArgs e) { from.OnFreedUp += from_OnFreedUp(); elist.Add(e); } private form_OnFreedUp() { if (elist.count == 0) return; form.Invoke((MethodInvoker)delegate { form.UpdateUI(elist[0]); }); elist.Remove(elist[0]); } In this case, how would I write an event that will notify that the form is free? and c) an other ideas?

  • GTK+: How do I process RadioMenuItem choice without marking it chosen? And vise versa

    - by eugene.shatsky
    In my program, I've got a menu with a group of RadioMenuItem entries. Choosing one of them should trigger a function which can either succeed or fail. If it fails, this RadioMenuItem shouldn't be marked chosen (the previous one should persist). Besides, sometimes I want to set marked item without running the choice processing function. Here is my current code: # Update seat menu list def update_seat_menu(self, seats, selected_seat=None): seat_menu = self.builder.get_object('seat_menu') # Delete seat menu items for menu_item in seat_menu: # TODO: is it a good way? does remove() delete obsolete menu_item from memory? if menu_item.__class__.__name__ == 'RadioMenuItem': seat_menu.remove(menu_item) # Fill menu with new items group = [] for seat in seats: menu_item = Gtk.RadioMenuItem.new_with_label(group, str(seat[0])) group = menu_item.get_group() seat_menu.append(menu_item) if str(seat[0]) == selected_seat: menu_item.activate() menu_item.connect("activate", self.choose_seat, str(seat[0])) menu_item.show() # Process item choice def choose_seat(self, entry, seat_name): # Looks like this is called when item is deselected, too; must check if active if entry.get_active(): # This can either succeed or fail self.logind.AttachDevice(seat_name, '/sys'+self.device_syspath, True) Chosen RadioMenuItem gets marked irrespective of the choose_seat() execution result; and the only way to set marked item without triggering choose_seat() is to re-run update_seat_menu() with selected_seat argument, which is an overkill. I tried to connect choose_seat() with 'button-release-event' instead of 'activate' and call entry.activate() in choose_seat() if AttachDevice() succeeds, but this resulted in whole X desktop lockup until AttachDevice() timed out, and chosen item still got marked.

  • Android - update widget text

    - by david
    Hi, i have 2 questions about widgets update I have 2 buttons and i need to change one button text when i press the other one, how can i do this? The first time i open the widget it calls the onUpdate method, but it never calls it again. I need to update the widget every 2 seconds and i have this line in the xml. android:updatePeriodMillis="2000" Do i need a service or should it works just with the updatePeriodMillis tag? onUpdate method RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.newswidget); Intent intent = new Intent(context, DetalleConsulta.class); intent.putExtra(DetalleConsulta.CONSULTA_ID_NAME, "3"); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); views.setOnClickPendingIntent(R.id.btNews, pendingIntent); /* Inicializa variables para llamar el controlador */ this.imei = ((TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId(); this.controlador = new Controlador(this.imei); try { this.respuestas = this.controlador.recuperarNuevasRespuestas(); if(this.respuestas != null &amp;&amp; this.respuestas.size() &gt; 0){ Iterator&lt;Consulta&gt; iterRespuestas = this.respuestas.iterator(); views.setTextViewText(R.id.btNews, ((Consulta)iterRespuestas.next()).getRespuesta()); } } catch (PersistenciaException e) { //TODO manejar error } appWidgetManager.updateAppWidget(appWidgetIds, views); thx a lot!!!

  • Bug on submitted app binary but not in the simulator - CALayer position contains NaN

    - by Jonathan Thurft
    I submitted my app to the App Store where is ready to download. I've since then received some interesting crash reports when people select an image from the ImagePicker in one of my views. This bug (see below) makes the app crash. I was wondering 2 things. Can anyone spot the problem in the code below? How do you deal with bugs that are only in the App Binary but do not show up when trying to recreate them on the dev environment? - I can make the app crash with the Binary that is on the app store but when I do the same on the simulator or on my test phone the app works perfectly.. The Crash report in BugSense CALayer position contains NaN: [798 nan] Class: CALayerInvalidGeometry 0x00120e99 -[imageCroppingViewController imagePickerController:didFinishPickingMediaWithInfo:] (imageCroppingViewController.m:126) + 163481 The Code - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; imageView.image = image; CGRect rect; rect.size.width = image.size.width; rect.size.height = image.size.height; imageView.center = scrollView.center; [imageView setFrame:rect]; scrollView.contentSize = imageView.frame.size; self.navigationController.navigationBar.hidden = NO; [myPicker.view removeFromSuperview]; }

  • In Castle Windsor, can I register a Interface component and get a proxy of the implementation?

    - by Thiado de Arruda
    Lets consider some cases: _windsor.Register(Component.For<IProductServices>().ImplementedBy<ProductServices>().Interceptors(typeof(SomeInterceptorType)); In this case, when I ask for a IProductServices windsor will proxy the interface to intercept the interface method calls. If instead I do this : _windsor.Register(Component.For<ProductServices>().Interceptors(typeof(SomeInterceptorType)); then I cant ask for windsor to resolve IProductServices, instead I ask for ProductServices and it will return a dynamic subclass that will intercept virtual method calls. Of course the dynamic subclass still implements 'IProductServices' My question is : Can I register the Interface component like the first case, and get the subclass proxy like in the second case?. There are two reasons for me wanting this: 1 - Because the code that is going to resolve cannot know about the ProductServices class, only about the IProductServices interface. 2 - Because some event invocations that pass the sender as a parameter, will pass the ProductServices object, and in the first case this object is a field on the dynamic proxy, not the real object returned by windsor. Let me give an example of how this can complicate things : Lets say I have a custom collection that does something when their items notify a property change: private void ItemChanged(object sender, PropertyChangedEventArgs e) { int senderIndex = IndexOf(sender); SomeActionOnItemIndex(senderIndex); } This code will fail if I added an interface proxy, because the sender will be the field in the interface proxy and the IndexOf(sender) will return -1.

  • Does std::vector change its address? How to avoid

    - by kunigami
    Since vector elements are stored contiguously, I guess it may not have the same address after some push_back's , because the initial allocated space could not suffice. I'm working on a code where I need a reference to an element in a vector, like: int main(){ vector<int> v; v.push_back(1); int *ptr = &v[0]; for(int i=2; i<100; i++) v.push_back(i); cout << *ptr << endl; //? return 0; } But it's not necessarily true that ptr contains a reference to v[0], right? How would be a good way to guarantee it? My first idea would be to use a vector of pointers and dynamic allocation. I'm wondering if there's an easier way to do that? PS.: Actually I'm using a vector of a class instead of int, but I think the issues are the same.

  • Utility to indexing a directory?

    - by achacha
    Here is what I am trying to do: I have a directory (with sub-directories) with source files, I need to index them so I can find files fast (find as I type) so I can open them for compare/analysis. I don't want it to scan the content, just filename index for quick lookup. I do this when trying to determine if a class exists in a given tree (we maintain directory trees for each release which has a lot of files) and sometimes I want to quickly check files to see how something was implemented, etc. Most of these directories are on remote servers (sometimes on the other side of the world) or on a VM (which is on a server far away), so I only want to read the directory trees once, which is why running find every time is way too slow and doing 'find . foo.txt' and then searching that is a bit tedious. It's kind of like how "Find Resource" works in eclipse after it indexes all files, but it's a bit of a chore to import/remove directories into eclipse every time. Eclipse is also very slow when dealing with remote volumes. Any suggestions are appreciated :)

  • ASP.NET Custom/User Control With Children

    - by Bob Fincheimer
    I want a create a custom/user control that has children (NOT a template control). For Example, I want my control to have the following markup: <div runat="server" id="div"> <label runat="server" id="label"></label> <div class="field"> <!-- INSERT CHILDREN HERE --> </div> </div> and when I want to use it on a page I simply: <ctr:MyUserControl runat="server" ID="myControl"> <span>This is a child</span> <div>And another <b>child</b> </ctr:MyUserControl> The child controls inside my user control will be inserted into my user control somewhere. What is the best way to accomplish this. The functionality is similar to a asp:PlaceHolder but I want to add a couple more options as well as additional markup and the such. Also the child controls still need to be able to be accessed by the page.

  • Response Redirect - Open Link in New Window

    - by bacis09
    First, I've taken the time to review this question which seems to be the most similar, however, the solution that seems to have been selected will not work in my scenario.Not to mention I worry about some of the comments claiming it to be brittle or an inadequate solution. http://stackoverflow.com/questions/104601/asp-net-response-redirect-to-new-window -We have an XML document which basically contains all of the information for a Side menu. -We have numerous URLS which are stored in a constants class. -One of the elements in a string of XML (well call it label) is used to determine if the menu item is created as a LinkButton or a Label. -Links use a custom user control that is used standard for all links across the application (why suggestion on similar thread doesn't work - I don't want all links to open in a new window - just one) -One of the elements in a string of XML (well call it function) is used in a Switch statement to generate our links using Response Redirect. It may look something like this. switch (function) { case goto 1: string url; if (user_group == 1) { url = Constants.CONSTANT1 } else { url = Constants.CONSTANT2 } Response.Redirect(url) case goto 2: ...... default: ...... break; } Given this scenario, I'm trying to find the best way to quickly open a New Window, when a specific case in this switch statement is met. Can it be done with Response Redirect (this seems to be arguable - people say no it can't, yet other people say they have made it work)? If not, what alternative can work here?

  • possible to make codeigniter work with another framework?

    - by ajsie
    the situation is this. my client (who also is a programmer) asks me to develop an address book (with mysql database) with a lot of functions. then he can interact with some class methods i provide for him. kinda like an API. the situation is that the address book application is getting bigger and bigger, and i feel like its way better to use CodeIgniter to code it with MVC. i wonder if i can use codeigniter, then in some way give him the access to controller methods. eg. in a controller there are some functions u can call with the web browser. public function create_contact($information) {..} public function delete_contact($id) {..} public function get_contact($id) {..} however, these are just callable from web browser. how can i let my client have access to these functions like an API? then in his own application he can use: $result = $address_book-create_contact($information); if($result) { echo "Success"; } $contact = $address_book-get_contact($id); is this possible? cause i just know how to access the controller methods with the webbrowser. and i guess its not an option for him to use header(location) to access them. all suggestions to make this possible are welcomed! thanks

  • Moving checkmarks in checkbox lists after page reload - Firefox only

    - by DaveS
    I'm getting some strange behavior in Firefox whenever I put checkboxes inside a list (ol, ul, dl), and then dynamically insert buttons above the list. If I start with a something simple list like this: <dl class="c"> <dt><label for="a1"><input type="checkbox" id="a1" />one</label></dt> <dt><label for="a2"><input type="checkbox" id="a2" />two</label></dt> <dt><label for="a3"><input type="checkbox" id="a3" />three</label></dt> </dl> and add some jQuery like this: $(document).ready(function(){ var a = $('<button type="button">a</button>'); var b = $('<button type="button">b</button>'); $('<div/>').append(a).append(b).insertBefore($('.c')); }); ...then open it in Firefox, it looks fine at first. But check the first checkbox, reload the page, and the check-mark jumps to the second box. Reload again, and it jumps to the third. Reload yet again, and no checkboxes are left checked. If I leave out one of the buttons by dropping one of the append calls, it's fine. If I change the buttons to divs or something similar, it's fine. If I replace the dl tag with a div (and get rid of the dt tags), it's fine. But I need both buttons, and the checkboxes have to be in a list for what I'm trying to build. Does anybody know what's causing this?

  • Will these security functions be enough? (PHP)

    - by ggfan
    I am trying to secure my site so I don't have sql injections and xss scripting. Here's my code. //here's the from, for brevity, i just show a field for users to put firstname <form> <label for="first_name" class="styled">First Name:</label> <input type="text" id="first_name" name="first_name" value="<?php if (!empty($first_name)) echo $first_name; ?>" /><br /> //submit button etc </form> if (isset($_POST['submit'])) { //gets rid of extra whitesapce and escapes $first_name = mysqli_real_escape_string($dbc, trim($_POST['first_name'])); //check if $first_name is a string if(!is_string($first_name) { echo "not string"; } //then insert into the database. ....... } mysqli_real_espace_string: I know that this func escapes certain letters like \n \r, so when the data gets inputted into the dbc, it would have '\' next to all the escaped letters? --Will this script be enough to prevent most sql injections? just escaping and checking if the data is a string. For integers values(like users putting in prices), i just: is_numeric(). --How should I use htmlspecialchars? Should I use it only when echoing and displaying user data? Or should I also use this too when inputting data to a dbc? --When should I use strip_tags() or htmlspecialchars? SOO with all these function... if (isset($_POST['submit'])) { //gets rid of extra whitesapce and escapes $first_name = mysqli_real_escape_string($dbc, trim($_POST['first_name'])); //check if $first_name is a string if(!is_string($first_name) { echo "not string"; } //gets rid of any <,>,& htmlspecialchars($first_name); //strips any tags with the first name strip_tags($first_name) //then insert into the database. ....... } Which funcs should I use for sql injections and which ones should I use for xss?

  • changes in main.xml are not reflected in the android app in netbeans

    - by nitish712
    I am new to android apps. I am using the netbeans 7.0.1 IDE to develop android apps. I have written the following code in the main java file: package com.test.helloworld; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class helloworld extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TextView t1=new TextView(this); t1.setText("hello world..!!!!"); setContentView(t1); } } This was working fine. I edited the main.xml file to display a textfield and button as follows: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button_send"/> <EditText android:id="@+id/edit_message" android:layout_width="wrap_content" android:layout_height="wrap_content" android:hint="@string/edit_message"/> </LinearLayout> Of course I have added all the corresponding strings in strings.xml. But when I try to run my app these weren't displaying... :( . I mean the same string that was displayed previously was being displayed. Can anybody figure out what is the mistake? thanx...

  • JQuery Autocomplete Form Submission

    - by user1658370
    I have managed to implement the jQuery autocomplete plugin on my website but was wondering if it is possible to make the form auto-submit once the user selects an item from the search. I have the following set-up: HTML Form: <form class="quick_search" action="../include/search.php" method="post"> <input type="text" name="search" id="search" value="Search..."> </form> JavaScript: $().ready(function() { $("#search").autocomplete("../include/search.php", { width: 350, selectFirst: false }); }); I have also included the jQuery and Autoplugin scripts. The search.php file contains a list of the search options. At the moment, the search works correctly and I just need it to submit the form once an item is selected from the list that appears. I tried to use the onClick and onSelect options within the search field but neither of these worked correctly. Any help would be much appreciated (I don't really understand js)! Thanks.
