How to display animation in a JTable cell

阅读更多关于 How to display animation in a JTable cell

问题 I am looking for a way to display an animated progress indicator (animated GIF, a rotating wheel rendered through Java2D etc., no preference here) in a table cell until the value that is to be finally displayed has been computed or retrieved. So far I have just put a static "pending..." text into each cell that is not yet ready to speed up display. As data arrives from a background thread I put it into the appropriate cell and call repaint on the table. With a static label or image this works

问题 Is it possible to restart an animated GIF used as background-image ? Consider this HTML: <div id="face"> <div id="eyes"></eyes> </div> And this style: #eyes.blink { background-image:url('blink.gif'); } I would like the blink.gif animation to play every time I add the class blink to #eyes , not just the first time.

阅读更多关于 How to keep animated gif running while doing intense calculations

问题 I have a page which does some intense and long lasting calculations in Javascript. I would like to have a loading animation to tell the user progress is being made. I have an animated gif now, but the whole browser window freezes (and the gif does not play) while the Javascript is running. Then when it's done, it unfreezes. The calculations must be client-side so they cannot be done on a server. Is there a way to keep Javascript from freezing the page and stopping animations from playing

How do you display an animated GIF in a Java application? Using swing you could simply use a JLabel public static void main(String[] args) throws MalformedURLException { URL url = new URL("<URL to your Animated GIF>"); Icon icon = new ImageIcon(url); JLabel label = new JLabel(icon); JFrame f = new JFrame("Animation"); f.getContentPane().add(label); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.pack(); f.setLocationRelativeTo(null); f.setVisible(true); } For loading animated gifs stored in a source package (in the source code), this worked for me: URL url = MyClass.class.getResource("/res

问题 I have an animated gif that I want to display any time a page is loading. When I view the image outside of a browser, the image loops infinitely and works just fine, but whenever I'm displaying the image in a browser, the animation only loops once.

Currently I'm just doing this to make the image appear which does make it appear, but only loops once: document.getElementById('ajaxloader').innerHTML = '<img src="images/ajax

阅读更多关于 How to resize an animated gif image using C#?

问题 Is there a method to create a copy of an animated gif image using C#? What I want is to generate a copy of a given gif image using the height and width parameters that the user provides.

Thanks. 回答1: It's not possible using the standard GD functions that come pre-packed with PHP. There is a class on phpclasses.org for this. I have never used it myself, but it's used by a lot of other packages. Alternatively, if you have access to ImageMagick from PHP, using either the MagickWand library or the
