Hi,
I have a widget that extends from Composite and that registers a listener
to DisposeEvent like this:
addDisposeListener(new DisposeListener() {
public void widgetDisposed(DisposeEvent e) {
if( gc.isDisposed() ){
gc.dispose();
}
}
});
public void widgetDisposed(DisposeEvent e) {
if( gc.isDisposed() ){
gc.dispose();
}
}
when the screen is disposed and the event is raized (i.e. widgetDisposed
is called) I got the following exception:
org.eclipse.swt.SWTException: Widget is disposed
