I have a case in which it is expensive to redraw a window, so I don’t want to do that repeatedly as the window is sized by the user…but I do want to redraw right at the end. So basically, I want to ignore all of the size events for the window except for the very last one.
I keep thinking that I’ve missed something obvious or something in the docs, but just can’t seem to figure out what the proper thing to do here is. I started off just setting a wx.Timer during the size event handler, but that does mean that there will be a delay between when the user lets up on the mouse button and the redraw of the window.
You could do your redraw of the contents in a Mouse left up event
handler, possibly checking a flag that you set in the On Resize Handler
to see if you need to do it.

Thanks Steve…the resizing, though is of a panel in the frame (the panel is resized as a result of a parent’s resize, basically) and not the frame itself, so I never see the mouse left up event.

So you would need to have a mouse up event handler bound to your frame,
(either as a part of the frame constructor or by doing a parent.Bind in
the panel constructor, that on a mouse up event checks if a resize has
been occurring and triggers your redraw.

Another alternative to Cody's solution is to use an EVT_IDLE handler
to catch your resizes (I actually use both solutions alternatively
when handling complex matplotlib or VTK wx-based panels). See if you
can adapt this solution:

To your problem.

Use a one shot timer to delay the processing. Each time your OnSize is
called start/re-start the timer so that the timer even will only fire
after a set interval when your last size event is received.
Perfect Andrea! Thanks so much!
