Notify application when pane is closed

[csh]

Hi,
I'd like to let my application know when a pane in a wxAuiManager is hidden by clicking the close button. I tried to capture an EVT_CLOSE or to override the virtual wxWindow::Show() function without success. The only thread I have found on a related topic was on the wxWidgets list, but there was no answer:
http://lists.wxwidgets.org/pipermail/wx ... 06722.html
so maybe I'm missing something very obvious. Any help would be greatly appreciated.

You can use EVT_AUI_PANE_CLOSE macro.
Call wxAuiManagerEvent::Veto() to cancel pane's closing.
