  • change fillColor of selected CAShapeLayer

    - by Frank
    I'm trying to change the fillColor of a CAShapeLayer when the layer it's contained in is touched. I'm able to change the background color of the tapped layer like this: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { CALayer *layer = [(CALayer *)self.view.layer.presentationLayer hitTest:point]; layer = layer.modelLayer; layer.backgroundColor = [UIColor blueColor].CGColor; } This turns the background of "layer" blue as expected. My problem is how do I change the color of the CAShapelayer inside "layer"? Thanks!

  • MediaElement.js setSrc() Loading The File But Not Changing pluginType

    - by doubleJ
    I'm working on a page that uses mediaelement.js to play mp3/mp4/wmv (yes, we have a lot of wmv). I have a list of links and those links should change the player. My effort is to make the changes to the player through javascript so that the page doesn't refresh. This code is working, but it refreshes every time. See a live demo of the non-ajax version. <?php $file = null; $file = $_GET["file"]; $format = null; if (preg_match("/mp4/i", $file)) $format = "mp4"; if (preg_match("/webm/i", $file)) $format = "webm"; if (preg_match("/wmv/i", $file)) $format = "wmv"; if (preg_match("/mp3/i", $file)) $format = "mp3"; if (preg_match("/ogg/i", $file)) $format = "ogg"; $mime = null; if ($format == "mp4") $mime = "video/mp4"; if ($format == "webm") $mime = "video/webm"; if ($format == "wmv") $mime = "video/wmv"; if ($format == "mp3") $mime = "audio/mp3"; if ($format == "ogg") $mime = "audio/ogg"; $element = "video"; if ($format == "mp3" || $format == "ogg") $element = "audio"; // you have to escape (\) the escape (\) character (hehehe...) $poster = "media\\120701Video.jpg"; $height = "360"; if ($format == "mp3") $height = "30"; ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>Embed</title> <link rel="stylesheet" href="include/johndyer-mediaelement-b090320/build/mediaelementplayer.min.css"> <style> audio {width:640px; height:30px;} video {width:640px; height:360px;} </style> <script src="include/johndyer-mediaelement-b090320/build/jquery.js"></script> <script src="include/johndyer-mediaelement-b090320/build/mediaelement-and-player.js"></script> </head> <body> <ul> <li><a href="embed.php">Reset</a></li> <li><a href="?file=media/120701Video-AnyVideoConverter.mp4">Alternative (mp4)</a></li> <li><a href="?file=media/120701Video-Ffmpeg-Defaults.webm">Alternative (webm)</a></li> <li><a href="?file=media/AreYouHurting-Death.wmv">Alternative (wmv)</a><li> <li><a href="?file=media/AreYouHurting-Death.mp3">Alternative (mp3)</a></li> </ul> <?php if ($file) { ?> <video src="<?php echo $file; ?>" controls poster="<?php echo $poster; ?>" width="640" height="360"></video> <div id="type"></div> <script> var video = document.getElementsByTagName("video")[0]; var player = new MediaElementPlayer(video, { success: function(player) { $('#type').html(player.pluginType); } }); <?php } ?> </script> </body> </html> This code requires <video> to be loaded, initially and with a file, so that the player mode (pluginType) is set. It will, then, only play formats that the pre-established mode supports (firefox in native mode won't play mp4).

I've read a couple pages that referenced refreshing the DOM after the javascript runs, but I haven't been able to successfully do it (I know enough about javascript to hack things around and get stuff working, but not enough to create whole new things). It is worth noting that Silverlight doesn't work with Internet Explorer 8 or Safari (not sure if it's my code, mejs, or the browsers). Also, neither Silverlight nor Flash play mp3 or webm (again, not sure where the problem lies). Is there a way to dynamically load different types of files into mediaelement?

  • Dynamic adding of usercontrols not showing control on page

    - by Phil
    I am trying to insert a user control dynamically into my default.aspx page via the following method in the page_init: Dim control As UserControl = LoadControl("~\Modules\Content.ascx") Controls.Add(control) When I run the page there is no sign of the usercontrol. Am I using the correct code to insert the usercontrol? Is there an alternative method of insertion available? Does the fact that the usercontrol has a page_load make a difference? Do I need to register the control in my aspx page at design time? Thanks in advance for any assistance you can offer.

  • What would you recommend to do simple 2D Graphics?

    - by Tom Ritter
    I want to build a program that will (as part of what it's doing) display lines organically growing and interacting horizontally across the screen. Here's a sample image, just imagine the lines sprouting from the left and growing to the right: The lines would look like the lines used on Google Maps Transit Overlay or OnNYTurf's transit pages. It's a personal project, so I'm open to just about any language and library combination. But I don't know where to start. What have you used in the past to create graphics that are similar to this? What would you recommend? I want it to run on Windows without any extras needed (.Net is fine), and it doesn't have to run elsewhere. I needs to run as an actual program, not javascript in the browser. There's obviously no 'right' answer to this, but the purpose isn't to start an argument about X better than Y but rather just find a list of graphics toolkits that do simple 2D graphics that people recommend because of their ease of use or community or whatever.

  • Optimising local image loading/rendering on iPhone

    - by Tricky
    Hi, I'm looking to create an interface where the user can navigate through large volumes of images. Each image has a thumbnail of 128x128 that I wish to display and will be kind of similar to coverflow in operation. I have this all working in principle but am becoming stuck when navigating through content at speed. The interface begins to stutter and becoming jerky. I believe this is primarily because of disk i/o and the cost of rendering each image. Is there anyway this can be handed over to a seperate thread simply? Defaulting to a greyed out thumbnail until the image has loaded? How have Apple managed to achieve this in coverflow? Many thanks,

  • Setting the colour scheme for a Silverlight app from an external resource

    - by Alex Angas
    I have a Silverlight 3 application containing six custom user controls. I'd like to load the colour scheme for these controls from an external resource. The code and XAML containing a default colour scheme would be built in the XAP. Then a parameter on the object tag would contain a URL from where alternate colours can be dynamically loaded. By the way, the Silverlight 3 application theme feature could be used if that's possible but is really overkill. Only colours need to be changed. Is this possible and how would you recommend to do it?

  • Mootools not loading fast enough IE6

    - by Tom
    Very random and annoying problem with IE6. We keep our common JS files on a resources server so we only have to update them in one place. As well as our custom classes we also keep our build of mootools and more on the resources server and link to it in the head of our sites. This is fine in all the browsers accept IE6. In IE6 it seems to not loads the core quick enough from the external link before trying to process the mootools code in my site.js file. It will go wrong on the first line "windows.addEvent". If i put a mootools core in a folder where the site is though its fine. Does anyone know why it might be doing this and if so a way around it, but still keeping the files on the resources domain? Thanks Tom

  • Standalone XULRunner app not loading the Flash player plugin

    - by Rajeesh
    Hi, I have created a standalone XUL application, and I copied "NPSWF32.dll"(flash plugin dll) to the "plugins" folder under the browser. When I launch the application, flash content is not getting displayed. If I set the MOZ_PLUGIN_PATH to the "plugins" directory before launching the application, everything is working as expected. Could someone tell me, what I needs to do in order to load the flash plugin automatically from the "plugins" folder. Thanks, Rajeesh

  • What is the fastest way to scale and display an image in Python?

    - by Knut Eldhuset
    I am required to display a two dimensional numpy.array of int16 at 20fps or so. Using Matplotlib's imshow chokes on anything above 10fps. There obviously are some issues with scaling and interpolation. I should add that the dimensions of the array are not known, but will probably be around thirty by four hundred. These are data from a sensor that are supposed to have a real-time display, so the data has to be re-sampled on the fly.

  • EAGLView orientation changes and strange buffering

    - by Drew
    I'm writing an app that offloads some heavy drawing into an EAGLView, and it does some lightweight stuff in UIKit on top. It seems that the GL render during an orientation change is cached somewhere, and I can't figure out how to get access to it. Specifically: After an orientation change, calling glClear(GL_COLOR_BUFFER_BIT) isn't enough to clear the GL display (drawing is cached somewhere?) How can I clear this cache? After an orientation change, glReadPixel() can no longer access pixels drawn before the orientation change. How can I get access to where this is stored?

  • Lazy property loading in Nhibernate and Spring

    - by Khash
    I'm using NHibernate 2.1.2 and Spring 1.3 I have two Text columns (blobs) in one of my classes. I'm trying to use lazy="true" for the mapping of those properties but NHProfiler still shows the two columns being added to the SELECT statement when the main object is loaded. I'm using Spring.NHibernate session factory and have configured ProxyFactory with both Castle and Spring with no luck.

  • DisplayObject.rotation not matching trig functions

    - by futuraprime
    I'm trying to label an animated pie chart, and I've been having a great deal of trouble getting rotated objects to line up with trigonometrically-positioned objects. So, for example, if I have a pie piece that's middle is angle theta and has been rotated n degrees in a tween, and then I try to position a label with code like this: label.x = center.x + Math.cos((theta + n)/180 * Math.PI) * radius; label.y = center.y + Math.sin((theta + n)/180 * Math.PI) * radius; the label is often not aligned with the center of the pie slice. Since I am also zooming in to the pie chart a great deal, the error becomes significant enough that it occasionally causes the label to miss the pie slice altogether. The error seems relatively unpredictable, and it looks a great deal like a rounding error, but I don't see any obvious rounding going on (the trig functions evaluate to ten or so decimal places, which should be more than enough here). How can I get these labels to position correctly?

  • Prevent deferred creation of controls.

    - by Scott Chamberlain
    Here is a test framework to show what I am doing, just create a new project add a tabbed control, on tab 1 put a button on tab 2 put a check box (default names) and paste this code for its code public partial class Form1 : Form { private List<bool> boolList = new List<bool>(); BindingSource bs = new BindingSource(); public Form1() { InitializeComponent(); boolList.Add(false); bs.DataSource = boolList; checkBox1.DataBindings.Add("Checked", bs, ""); } bool updating = false; private void button1_Click(object sender, EventArgs e) { updating = true; boolList[0] = true; bs.ResetBindings(false); Application.DoEvents(); updating = false; } private void checkBox1_CheckedChanged(object sender, EventArgs e) { if (!updating) MessageBox.Show("CheckChanged fired outside of updating"); } } The issue is if you run the program and look at tab 2 then press the button on tab 1 the program works as expected, however if you press the button on tab 1 then look at tab 2 the event for the checkbox will not fire untill you look at tab 2. The reason for this is the controll on tab 2 is not in the "created" state, so its binding to change the checkbox from unchecked to checked does not happen until after the control has been "Created". checkbox1.CreateControl() does not do anything because according to MSDN CreateControl does not create a control handle if the control's Visible property is false. You can either call the CreateHandle method or access the Handle property to create the control's handle regardless of the control's visibility, but in this case, no window handles are created for the control's children. I tried getting the value of Handle(there is no CreateHandle for Button) but still the same result. Any suggestions other than have the program quickly flash all of my tabs that have data-bound check boxes when it first loads?

  • Problem in loading Iframe in FireFox!

    - by maddy
    Hello all, I'm trying to load an aspx page using Iframe in VB.net. I'm trying to set the source of Iframe with the help of Ext (JavaScript). My aspx code: <div id="container"> < iframe id="pane" name="pane" src="Empty.aspx" frameborder="0" > </iframe> </div> My Javascript code: Pane = function() { var pane; return { init: function() { if (!document.body) { return; } pane = Ext.get('pane'); if ( something ) { this.load(); } else { this.navigateTo('Page.aspx?id=' + a.ID); } }, load: function() { pane.dom.src = 'HTTPURL'; }, navigateTo: function(url) { var agt = navigator.userAgent.toLowerCase(); if (agt.indexOf("firefox") != -1) { document.getElementById('pane').src = url; } else { pane.dom.src = url; } } }; } (); This works fine with IE and Iframe gets loaded with page.aspx every time the parent page is requested. But with FireFox it doesn't. With FireFox the src attribute remains "Empty.aspx" when the page is loaded but when I refresh the page i.e. in post back event the src attribute changes to "page.aspx?id=a.id" and iframe gets loaded properly. Has anyone faced such kind of problem before? If you know the solution please help me, it's killing me big. Thanks in advance. Maddy.

  • Animating a font size change in a UITableView

    - by nickthedude
    Hey Simple little app for educational purposes, its a simple uitableview and I want users to be able to use a uislider to adjust the font size as needed. The code I have now works to change the font but only when the view is updated, ie when i pull up or down the table view to reveal other cells. I'd like the font change to be reflected immediately as a user moves the uislider if possible, here's the code that I have working half way: -(UITableViewCell *) tableView: (UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SimpleTableIdentifier] autorelease]; NSUInteger row = [indexPath row]; cell.text = [listData objectAtIndex:row]; UIImage *image = [UIImage imageNamed:@"star.png"]; cell.font = [UIFont systemFontOfSize:[fontSlider value]]; cell.image = image; return cell; }

  • Custom event loop and UIKit controls. What extra magic Apple's event loop does?

    - by tequilatango
    Does anyone know or have good links that explain what iPhone's event loop does under the hood? We are using a custom event loop in our OpenGL-based iPhone game framework. It calls our game rendering system, calls presentRenderbuffer and pumps events using CFRunLoopRunInMode. See the code below for details. It works well when we are not using UIKit controls (as a proof, try Facetap, our first released game). However, when using UIKit controls, everything almost works, but not quite. Specifically, scrolling of UIKit controls doesn't work properly. For example, let's consider following scenario. We show UIImagePickerController on top of our own view. UIImagePickerController covers our custom view We also pause our own rendering, but keep on using the custom event loop. As said, everything works, except scrolling. Picking photos works. Drilling down to photo albums works and transition animations are smooth. When trying to scroll photo album view, the view follows your finger. Problem: when scrolling, scrolling stops immediately after you lift your finger. Normally, it continues smoothly based on the speed of your movement, but not when we are using the custom event loop. It seems that iPhone's event loop is doing some magic related to UIKit scrolling that we haven't implemented ourselves. Now, we can get UIKit controls to work just fine and dandy together with our own system by using Apple's event loop and calling our own rendering via NSTimer callbacks. However, I'd still like to understand, what is possibly happening inside iPhone's event loop that is not implemented in our custom event loop. - (void)customEventLoop { OBJC_METHOD; float excess = 0.0f; while(isRunning) { animationInterval = 1.0f / openGLapp->ticks_per_second(); // Calculate the target time to be used in this run of loop float wait = max(0.0, animationInterval - excess); Systemtime target = Systemtime::now().after_seconds(wait); Scope("event loop"); NSAutoreleasePool* pool = [[ NSAutoreleasePool alloc] init]; // Call our own render system and present render buffer [self drawView]; // Pump system events [self handleSystemEvents:target]; [pool release]; excess = target.seconds_to_now(); } } - (void)drawView { OBJC_METHOD; // call our own custom rendering bool bind = openGLapp->app_render(); // bind the buffer to be THE renderbuffer and present its contents if (bind) { opengl::bind_renderbuffer(renderbuffer); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } } - (void) handleSystemEvents:(Systemtime)target { OBJC_METHOD; SInt32 reason = 0; double time_left = target.seconds_since_now(); if (time_left <= 0.0) { while((reason = CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0, TRUE)) == kCFRunLoopRunHandledSource) {} } else { float dt = time_left; while((reason = CFRunLoopRunInMode(kCFRunLoopDefaultMode, dt, FALSE)) == kCFRunLoopRunHandledSource) { double time_left = target.seconds_since_now(); if (time_left <= 0.0) break; dt = (float) time_left; } } }

  • VisualAssert Testing in C++, Loading a test fixture.

    - by C_Bevan
    Good day, I am learning Testing in Visual Studio C++ and I have several tutorials which I have followed. I am trying to load a test fixture. I have tried to put the test .cpp file in many different places but it will still not pick up on it when I click on "Run Tests" or "Run Tests without debugging" In the tutorials I found, they seemed to load into the Test Explorer automatically, but in mine is an icon with a X + (PROJECTNAME).EXE and when I hoover over it I get the process exited without registering with the agent... this is due to the model not containing any test fixtures... How can I load my tests into the Test Explorer...or register them with my project... I've tried right click and "Add Fixture...".... but that just starts a new test file and I have the same problem. Anybody know how I solve this issue?

  • Managing of shared resources between classes?

    - by Axarydax
    Imagine that I have a several Viewer component that are used for displaying text and they have few modes that user can switch (different font presets for viewing text/binary/hex). What would be the best approach for managing shared objects - for example fonts, find dialog, etc? I figured that static class with lazily initialized objects would be OK, but this might be the wrong idea. static class ViewerStatic { private static Font monospaceFont; public static Font MonospaceFont { get { if (monospaceFont == null) //TODO read font settings from configuration monospaceFont = new Font(FontFamily.GenericMonospace, 9, FontStyle.Bold); return monospaceFont; } } private static Font sansFont; public static Font SansFont { get { if (sansFont == null) //TODO read font settings from configuration sansFont = new Font(FontFamily.GenericSansSerif, 9, FontStyle.Bold); return sansFont; } } }
