  • Changing scaling of MATLAB Figure

    - by Phil
    I have a figure that displays 20,000 points on the x-axis. So it labels the x-axis from 0 ... 20,000. However, now I would like to scale it from 0 to 50. But when I try to do this in the plot window it just shows me the first 50 points, instead of changing the scale. Is there any straightforward way to do that in MATLAB?

  • JToolbar is hidden by JMenu

    - by pierre
    I'm using Netbeans to add a JToolbar to my window which also has a JMenuBar. Here is the design-time look: .. but during run-time I get this: With the toolbar seemingly partially hidden under the menu names. This is on the Mac, btw. Is there something stupid I've forgotten to do or some layout trick I should be using? EDIT: I'll add that the area below the toolbar is a SplitContainer.

  • Visual Studio Question: How to go to a specific file path and line number programmatically?

    - by Jack
    In the Visual Studio output window, you can double click a line that contains a file path and line number and it automatically takes you to that location. In my program, I need to mimic this behavior and be able to click something (a button for example) and do go to a specific file and line number that I tell it to go to. Any help/suggestions would be appreciated. I am working in C#.

  • Scriptaculous Sortable.create - Can't hook the dragged element

    - by Tom
    When using Sortable.create I can't seem to get the element that is being dragged. Does Sciptaculous not fully implement all Draggable and Droppable features when you use sortable? Given: Sortable.create("sortArea", {scroll:window, onChange:orderLi}); function orderLi(){ console.log(this.draggables.each(function(e){if(e.dragging==true){return e};})); } My console always shows all the array of draggables. How do I only grab the one that is being dragged?

  • Precise explanation of JavaScript <-> DOM circular reference issue

    - by Joey Adams
    One of the touted advantages of jQuery.data versus raw expando properties (arbitrary attributes you can assign to DOM nodes) is that jQuery.data is "safe from circular references and therefore free from memory leaks". An article from Google titled "Optimizing JavaScript code" goes into more detail: The most common memory leaks for web applications involve circular references between the JavaScript script engine and the browsers' C++ objects' implementing the DOM (e.g. between the JavaScript script engine and Internet Explorer's COM infrastructure, or between the JavaScript engine and Firefox XPCOM infrastructure). It lists two examples of circular reference patterns: DOM element → event handler → closure scope → DOM DOM element → via expando → intermediary object → DOM element However, if a reference cycle between a DOM node and a JavaScript object produces a memory leak, doesn't this mean that any non-trivial event handler (e.g. onclick) will produce such a leak? I don't see how it's even possible for an event handler to avoid a reference cycle, because the way I see it: The DOM element references the event handler. The event handler references the DOM (either directly or indirectly). In any case, it's almost impossible to avoid referencing window in any interesting event handler, short of writing a setInterval loop that reads actions from a global queue. Can someone provide a precise explanation of the JavaScript ↔ DOM circular reference problem? Things I'd like clarified: What browsers are effected? A comment in the jQuery source specifically mentions IE6-7, but the Google article suggests Firefox is also affected. Are expando properties and event handlers somehow different concerning memory leaks? Or are both of these code snippets susceptible to the same kind of memory leak? // Create an expando that references to its own element. var elem = document.getElementById('foo'); elem.myself = elem; // Create an event handler that references its own element. var elem = document.getElementById('foo'); elem.onclick = function() { elem.style.display = 'none'; }; If a page leaks memory due to a circular reference, does the leak persist until the entire browser application is closed, or is the memory freed when the window/tab is closed?

  • Execute function every nth second

    - by timkl
    Total JacaScript n00b question right here: I've made this snippet that clicks a link after 10th second: function timeout() { window.setTimeout(function() { $('img.left').click(); }, 1000); setTimeout("timeout()", 1000); } timeout(); My question is, how do I execute this function every 10th second, instead of just once? Is this the best way to do this, or is there some kind of nifty jQuery method that you prefer?

  • Javascript: previous property is undefined

    - by Matrym
    Why is it saying that "lbp is undefined" on the line of "creditText"? How do I refer to previous properties in a config file such as this? var lbp = { // Pertinant page properties, such as Author, Keywords, URL or Title page: { theURL: window.location.toString(), }, // Configurable user defaults defaults: { creditText: lbp.page.theURL } } Thanks in advance for your help

  • Expert R users, what's in your .Rprofile?...

    - by gappy
    This question is maybe a little too cute, but I have always found startup profile files of other people both useful and instructive about the language. Moreover, while I have some customization for bash and vim, I have nothing for R. For example, one thing I always wanted is different colors for input and output text in a window terminal, and maybe even syntax highlighting.

  • How to scroll table view with toolbar at the top of the view

    - by Jakub
    Hello, I have a view with a toolbar at the top and a table view with text fields in it's cells. When I want to edit the text fields placed in the bottom of the table view the keyboard is hiding the text field being edited (as the table view is not scrolled up). I tried to implement http://cocoawithlove.com/2008/10/sliding-uitextfields-around-to-avoid.html but this makes my whole view move up (the toolbar and the table view) while I would like to have the toobar at the top of the view for the whole time. I modified the mentioned code to something like this: - (void)textFieldDidBeginEditing:(UITextField *)textField { CGRect textFieldRect = [tableView.window convertRect:textField.bounds fromView:textField]; CGRect viewRect = [tableView.window convertRect:tmpTableView.bounds fromView:tableView]; CGFloat midline = textFieldRect.origin.y + 0.5 * textFieldRect.size.height; CGFloat numerator = midline - viewRect.origin.y - MINIMUM_SCROLL_FRACTION * viewRect.size.height; CGFloat denominator = (MAXIMUM_SCROLL_FRACTION - MINIMUM_SCROLL_FRACTION) * viewRect.size.height; CGFloat heightFraction = numerator / denominator; if (heightFraction < 0.0) { heightFraction = 0.0; } else if (heightFraction > 1.0) { heightFraction = 1.0; } UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation]; if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) { animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction); } else { animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT * heightFraction); } CGRect viewFrame = tableView.frame; viewFrame.origin.y -= animatedDistance; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION]; [tableView setFrame:viewFrame]; [UIView commitAnimations]; } and - (void)textFieldDidEndEditing:(UITextField *)textField { CGRect viewFrame = tableView.frame; viewFrame.origin.y += animatedDistance; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION]; [tableView setFrame:viewFrame]; [UIView commitAnimations]; } This made my toolbar stay at the top, but unfortunately the table view overlays the toolbar and the toolbar is not visible. Any ideas how to solve this?

  • Where does _CrtDbgReportW ouput in Windows Mobile?

    - by Ignas Limanauskas
    I am using ASSERTE macro to check for pre-conditions. According to its definition it is using ASSERT_BASE, which in turn calls _CrtDbgReportW to print out the message. Where does _CrtDbgReportW output goes to? I would assume that if the application is started from debugger, it would go to debugger window. Where would the messages go if it is not under debugger?

  • Live javascript debugging by recording function calls and parameters

    - by Jenko
    Is there a debugging system that allows me to record javascript function calls and their parameters as they occur? this would allow me to trace and debug applications in live/client situations without the performance hit due to manual logging. Edit: I'm not talking about manually calling functions using a 'console' window and viewing the results, or manually adding 'trace' or 'log' commands into my javascript. I need it to work with any running javascript.

  • jQuery: resizing element cuts off parent's background

    - by Justine
    Hi, I've been trying to recreate an effect from this tutorial: http://jqueryfordesigners.com/jquery-look-tim-van-damme/ Unfortunately, I want a background image underneath and because of the resize going on in JavaScript, it gets resized and cut off as well, like so: http://dev.gentlecode.net/dotme/index-sample.html - you can view source there to check the HTML, but basic structure looks like this: <div class="page"> <div class="container"> div.header ul.nav div.main </div> </div> Here is my jQuery code: $('ul.nav').each(function() { var $links = $(this).find('a'), panelIds = $links.map(function() { return this.hash; }).get().join(","), $panels = $(panelIds), $panelWrapper = $panels.filter(':first').parent(), delay = 500; $panels.hide(); $links.click(function() { var $link = $(this), link = (this); if ($link.is('.current')) { return; } $links.removeClass('current'); $link.addClass('current'); $panels.animate({ opacity : 0 }, delay); $panelWrapper.animate({ height: 0 }, delay, function() { var height = $panels.hide().filter(link.hash).show().css('opacity', 1).outerHeight(); $panelWrapper.animate({ height: height }, delay); }); }); var showtab = window.location.hash ? '[hash=' + window.location.hash + ']' : ':first'; $links.filter(showtab).click(); }); In this example, panelWrapper is a div.main and it gets resized to fit the content of tabs. The background is applied to the div.page but because its child is getting resized, it resizes as well, cutting off the background image. It's hard to explain so please look at the link above to see what I mean. I guess what I'm trying to ask is: is there a way to resize an element without resizing its parent? I tried setting height and min-height of .page to 100% and 101% but that didn't work. I tried making the background image fixed, but nada. It also happens if I add the background to the body or even html. Help?

  • Problem adding Viewport2DVisual3D from Code

    - by Jeff
    I'm trying to add a Viewport2DVisual3D to a Viewport3D in code, but the visual isn't showing up. Any help understanding why not would be appreciated. The following is the code for the main window. Is it sufficient to just add the Viewport2DVisual3D to the children of the Viewport3D in order for it to be rendered? public partial class Window1 : System.Windows.Window { public Window1() { InitializeComponent(); this.Loaded += new RoutedEventHandler(temp); } public void temp(object sender, RoutedEventArgs e) { Viewport2DVisual3D test = new Viewport2DVisual3D(); MeshGeometry3D testGeometry = new MeshGeometry3D(); Vector3D CameraLookDirection = Main_Target_CameraOR20.LookDirection; // Calculate the Positions based on the Camera Point3DCollection myPoint3DCollection = new Point3DCollection(); myPoint3DCollection.Add(new Point3D(-1, 1, 0)); myPoint3DCollection.Add(new Point3D(-1, -1, 0)); myPoint3DCollection.Add(new Point3D(1, -1, 0)); myPoint3DCollection.Add(new Point3D(1, 1, 0)); testGeometry.Positions = myPoint3DCollection; PointCollection myPointCollection = new PointCollection(); myPointCollection.Add(new Point(0, 0)); myPointCollection.Add(new Point(0, 1)); myPointCollection.Add(new Point(1, 1)); myPointCollection.Add(new Point(1, 0)); testGeometry.TextureCoordinates = myPointCollection; Int32Collection triangleIndicesCollection = new Int32Collection(); triangleIndicesCollection.Add(0); triangleIndicesCollection.Add(1); triangleIndicesCollection.Add(2); triangleIndicesCollection.Add(2); triangleIndicesCollection.Add(3); triangleIndicesCollection.Add(0); testGeometry.TriangleIndices = triangleIndicesCollection; DiffuseMaterial myDiffuseMaterial = new DiffuseMaterial(Brushes.White); Viewport2DVisual3D.SetIsVisualHostMaterial(myDiffuseMaterial, true); Transform3DGroup myTransform3DGroup = new Transform3DGroup(); ScaleTransform3D myScaleTransform3D = new ScaleTransform3D(); myScaleTransform3D.ScaleX = 2; myScaleTransform3D.ScaleY = 2; myScaleTransform3D.ScaleZ = 2; TranslateTransform3D myTranslateTransform3D = new TranslateTransform3D(); myTranslateTransform3D.OffsetX = -27; myTranslateTransform3D.OffsetY = 13; myTranslateTransform3D.OffsetZ = 6; RotateTransform3D rotateTransform = new RotateTransform3D() { Rotation = new AxisAngleRotation3D { Angle = -50, Axis = new Vector3D(0, 1, 0) } }; myTransform3DGroup.Children.Add(myTranslateTransform3D); myTransform3DGroup.Children.Add(myScaleTransform3D); myTransform3DGroup.Children.Add(rotateTransform); test.Transform = myTransform3DGroup; Button myButton = new Button(); myButton.Content = "Test Button"; test.Material = myDiffuseMaterial; test.Geometry = testGeometry; test.Visual = myButton; ZAM3DViewport3D.Children.Add(test); } }
