Re: [wxperl-users] trapping events (was: custom painting)

[Dave R. <dav...@ma...>]

I agree, it's not the best way to go, but the question has come up again 
for another reason now.

if I have an object derived from Wx::Frame which contains a 
Wx::SplitterWindow, the splitter is correctly sized inside the frame 
upon window resize. however, if i trap the frame resize using 
EVT_SIZE(), the default splitter resizing doesn't happen.

how can I trap the event for notification purposes, yet call the default 
behaviour first?

sub OnSize {
	my ($self,$event) = @_;
	
	# call default behaviour
	$event->Handle();

	# respond to resize
	$self->DoOtherStuffWhenResized();
}

thanks,
/dave
