I use wxAUI in an MDI application (thks for 0.9.1) ... And look is very pretty ...
But I still have a problem ... I put a progress control in the MDI parent frame status bar. And I need to catch size event to put my progress at the right place (in its dedicated pane). wxAUI push its event handler (wxFrameManager) in front of the native frame one. As you catch size event, the managed frame does not receive any sizing event and my progress bar stays wxDefaultSize & wxDefaultPosition !!!
I think that events you catch should be skipped to allow client application to receive them after wxFrameManager. This allow some customization like drawing an MDIClientWnd background or to manage control position in status bar ...
Thxs a lot for this great library
