I am trying to implement position-sensitive zooming inside a JScrollPane. The JScrollPane contains a component with a customized 'paint' that will draw itself inside whatever space it is allocated - so zooming is as easy as using a MouseWheelListener that resizes the inner component as required. But I also want zooming into (or out of) ...
Most modern apps provide an interactive way to push a long running operation onto a background queue. I am developing a swing application and I have implemented a simple "framework" to support that. However, I can't help but think that something like that must exist already. I have heard that Netbeans provides that, but I don't want to m...

I'm writing a custom file selection component. In my UI, first the user clicks a button, which pops a JFileChooser; when it is closed, the absolute path of the selected file is written to a JTextField. The problem is, absolute paths are usually long, which causes the text field to enlarge, making its container too wide. I've tried this...
Hello, I have a swing gui with a tabbed pane in the north. Several key events are added to its input map: InputMap paneInputMap = pane.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT); paneInputMap.put( KeyStroke.getKeyStroke( KeyEvent.VK_E, KeyEvent.CTRL_MASK ), "finish"); paneInputMap.put( KeyStroke.getKeyStroke( KeyEvent.V...

I am trying to make a JTable that has column spans available. Specifically, I am looking to nest a JTable inside another JTable, and when the user clicks to view the nested table, it should expand to push down the rows below and fill the empty space. This is similar to what you see in MS Access where you can nest tables, and clicking the...
I made a Java Applet with some Standard GUI Components on it. I used the MigLayout Manager. If I move the mouse slowly over the various GUI Components everything appears to be fine, but if I move the mouse fast, it flickers. What could make that nasty ugly redraw? (Core 2 Duo 6300, 2GB Ram, Windows XP) ...

I'd like to add scrolling capability to a javax.swing.JDesktopPane. But wrapping in a javax.swing.JScrollPane does not produce the desired behavior. Searching the web shows that this has been an issue for quite some time. There are some solutions out there, but they seem to be pretty old, and I'm not not completely satisfied with them. ...

The animation does not play. If I load the animated gif from a file on the f...
I'm writing a Java Tree in which tree nodes could have children that take a long time to compute (in this case, it's a file system, where there may be network timeouts that prevent getting a list of files from an attached drive). The problem I'm finding is this: getChildCount() is called before the user specifically requests opening a...
I'm not happy with the rendering of HTML by Swing's JEditorPane. In particular bullets for unordered lists are hideous. Customising the rendering seems extremely difficult. Therefore I'm looking for a replacement with better HTML rendering. Does this exist? (I asked Google, and found nothing except a promising dead link). ...
