How can I avoid, that a dialog is shown, when there already is one on the screen? Details: In my application many Timers are running. If a fatal error occurs, all the affected threads are going to show a JDialog (by swingx.JXErrorPane.showDialog()), which is not desired. Even if I cancel all the running Timers, still some Dialogs will a...
I need to send some events to a component in Swing, so it is handled just like any user generated, standard Swing events. Basically, something like a macro recorder, and then executor for JEditorPane. But I need more control over the generated events. SO, assume I have an editor, I want to: capture all events sent to it, and at that...
I want to store a JFrame's location (bounds, extendedState) when the user closes it. However, when the user moves the frame onto the 2nd screen and maximizes it, how can I store that information? My naive (and single display) implementation is like this: void saveFrame(JFrame frame) throws IOException { Properties props = new Prope...

I'm using NetBeans 6.5.1 with jdk1.6.0_13. I've used the new project wizard to create a basic Java/Swing desktop application. This is a SingleFrameApplication that uses...
I have written a class that extends JPanel. Is it possible to use this in the NetBeans GUI Builder and have it survive all of the automatic code generation? I have used the customised code option in the GUI builder to instantiate the object as the new class, but it seems like the declaration can't be changed from JPanel, so only method...

Hi! I'm trying to change a JList inside a JScrollPane dynamically, using myList.setListData(someArray); After this I would expect the JScrollPane to show Scrollbars as needed, but this doesn't happen.

This is driving me absolutely insane. I know that, to change the formatting of table cells with JTable, I have to use my own renderer. But I cannot seem to implement this properly. This is my current setup: public class MyClass { public static void main(String args[]) { JTable myTable = new JTable(10, 10); myTable.se...

So I decided to ask the StackOverflow community: Where can I find information about customizing Java GUI Components in general?

That means if the JDialog will be shown and the user clicks "OK" or "CANCEL" the main application looses its focus and will be pushed into the background. After my investigation I found out, that this behaviour only happens if I disable my main frame for the time I...

In order to make it close, I set closeable to t...
