I'm having trouble understanding how QGraphicsItemAnimation's setScaleAt function works. Here's the code I'm using: QGraphicsItem *item=scene.addEllipse(400, 300, 100, 100, QPen(), QBrush(Qt::SolidPattern)); QTimeLine *timeline=new QTimeLine(3000); timeline->setFrameRange(0, 100); QGraphicsItemAnimation *animation=new QGraphicsI...
In the jQuery example below, I have one div inside another. When I animate the inner div down to a width of 0, the outer div (which has absolute positioning), decreases in width along with it. This is desired. The trouble is that after the animation is complete, the outer div pops back to its original size. Is this expected? How can I ...
I have a View that has a UIWebView, and an OptionsPane (Custom UIViewController with Custom view). I want when the view is shown, for the options pane (located on the top of the main view) to FLIP into place. I am using the code, and I am getting a strange result. The FIRST time the view is shown, the options pane seems to already be v...
I remember seeing this on Ajaxian and a couple other sites but I never bookmarked it, now i can't find it again. It's a javascript library that allows you to move your mouse over an image that's been chopped into layers and change perspective. Any links would be appreciated. ...
Hello, I want to wobble an image back and forth in my application similar to how the iPhone icons wobble when you press down on it. What's the best way to do that? This is my first foray into animations that's not using an animated GIF. I think the idea is to slightly rotate the image back and forth to create the wobbling effect. ...
I have this jQuery: $(document).ready(function() { $("#panel").hide(); $('.login').toggle( function() { $('#panel').animate({ height: "150", padding:"20px 0", backgroundColor:'#000000', opacity:.8 }, 500); }, function() { $('#panel').animate({ height: "0", padding:"...

What i am trying to do is start fadein and don't wait for it to finish (which appears to be happening at the moment) .. and start the animate.. hence both...
I have a simple WPF application that contains a user control that is animated in and out by a pair of storyboards on the main window. I am animating the user control's opacity, scaletransform.scalex and scaletransform.scaley to pop it in and out of view. It looks cool except for the first time it runs. The animation is set to take 3/1...
I want to trigger an event handler when the user hovers on a particular part of the image, like the center of the image or the right side of the image (area would include, say, about a 100 pixels). I am not using any framework, so this is normal javascript that I am working with. I am not sure if using image maps would work. Can anyone h...
I can't capture/trigger OnMouseEnter or OnMouseLeave events through C# code for list items. To be clear, I don't need an OnSelectedItem event. What I want to do is to be able to handle the OnMouseEnter and OnMouseLeave events for ListBoxItem which will start the DoubleAnimation for that ListBoxItem - I want to enlarge its font on Mouse...
Hi, I am currently developing an iPhone game that has numerous animations using image sequences (jpg and png with transparencies). Using Instruments to view Leaks and Object Allocations, the most I've seen the object allocations go up to is less than 500k. However, the program still crashes and quits unexpectedly when we switch from one...
I want to show the user how many seconds have passed since some event occurs. Conceptually, my view model has properties like this: public DateTime OccurredAtUtc { get; set; } public int SecondsSinceOccurrence { get { return (int)(DateTime.UtcNow - OccurredAtUtc).TotalSeconds; } } If I bind a TextBlock.Text property to SecondsSi...
I'm writing a simple control in C# that works like a picture box, except the image is constantly scrolling upwards (and re-appearing from the bottom). The animation effect is driven by a timer (System.Threading.Timer) which copies from the cached image (in two parts) to a hidden buffer, which is then drawn to the control's surface in it...
Here is my XAML for a TabItem. I want to be able to set the Color of a single gradient stop in a trigger. I know that I can re-define the gradient completely in the trigger's setter, but I want to access a specific property on the background so I can animate it in the future. I have tried every variation of everything in the trigger's s...
OK, I'm making a GUI for my MP3 player using WPF and I have a border that enlarges its width property for every second of the played track, thus making a "Progress Bar" for the currently played song. I named the border ProgressBarBorder. After the whole playlist is complete, I wanted to use a DoubleAnimation to fade out the border. Now, ...
I can't figure out what I'm missing here. Here's the problem: Consider a (Control|Data)Template with a Trigger that switches visibility of some inner UI elements. E.g. show a TextBlock when IsReadOnly==true and show a TextBox when IsReadOnly==false. Everything is perfect if you do this without animation - one or two setters would do th...
I am having a problem trying to animate between 2 UIImage. I did implement the setAnimationDidStopSelector methods so once my first animation is finish I start my second one, but when I tried to flip to my previous image it still flipping to the same image as if the variable didn't take into the account the new value of my image object ...
What is the easiest and most practical way to implement smooth frame-based animation on the iPhone? I know that image sequences are easy to do, but if I have say 30 images flashing per second (30 fps) for 5 seconds, will it freeze up? Are there massive memory implications with this method? I'm designing a game that will be mostly static...
