Hi
I am new to SWT and came across the following problem (bare with me, this
will get a bit lengthy):
I am trying to add an editor to a table, which works fine. The editor is of
type Combo. In the example for the editor, the editor will get disposed when
a new editor gets created, something like
Control oldEditor = editor.getEditor()
if (oldEditor != null) oldEditor.dispose()
This works as well, but is not very pretty, especially if I want to add
sorting of columns and even after pressing the column header I still have
the editor in place. So I thought I would be clever and added this code:
Listener comboListener = new Listener() {
public void handleEvent(Event event) {
switch(event.type) {
case SWT.FocusOut:
item.setText(2, categories[combo.getSelectionIndex()]);
editor.getEditor().dispose();
break;
case SWT.Traverse:
switch(event.detail) {
case SWT.TRAVERSE_RETURN:
item.setText(2, categories[combo.getSelectionIndex()]);
// fall through
case SWT.TRAVERSE_ESCAPE:
editor.getEditor().dispose();
event.doit = false;
}
break;
}
}
};
combo.addListener (SWT.FocusOut, comboListener);
combo.addListener (SWT.Traverse, comboListener);
To my surprise, when I loose focus or tab out of the editor -->> Eclipse
crashes! The JVM falls over, without leaving any hint in the .log file.
Is there something I did wrong or is this a bug? The code is a variation an
a theme I found in the documented examples on the eclipse.org site.
This is
Eclipse 2.1.1
Windows XP SP1
SUN JVM 1.4.2
Any ideas?

Noone interested in replying to this question? Is this the wrong forum for
bugs?

This could be because you are using SUN JVM 1.4.2
See:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=40884
Try using a 1.4.1 VM or the latest 3.0 version of Eclipse with the 1.4.2 VM.
