Hi,
Below is a very simple code snippet that reproduces a problem that I'm
seeing in an editor that uses SWT_AWT.new_Frame() to embed an
existing swing application.
public void createPartControl(Composite parent)
{
Composite panel = new Composite(parent, SWT.EMBEDDED);
Frame frame = SWT_AWT.new_Frame(panel);
/*
* Other code here that is not needed to reproduce the problem
* ...
*/
}
After the editor is disposed of, if I maximize or minimize the workbench
shell, the exception below is generated and the workbench becomes
unusable. I'm seeing the problem with the latest stable build (RC1) on
Win32.
Is this a bug, or do I need to do some extra disposal work in my editor?
