What is the right way to tell if an aui pane is shown?

I’m testing out wx.lib.agw.aui.AuiManager for a layout.

One issue I have is I get lots of events in my managed frame:

EVT_AUI_PANE_[DOCKED,FLOATED,CLOSE] and EVT_AUI_PERSPECTIVE_CHANGED.

I don’t however get EVT_AUI_PANE_ACTIVATED. I can listen to a combination of perspective changed and closed I think and then query the PaneInfo to see if a given panel is visible but this doesn’t seem like the desired behavior. Thoughts?

I’m on Fedora 18 w/ wx 2.8.12
