We have experienced some issues with CXTPDockingPaneAutoHideWnd. It appears that at some point m_pPane gets Nulled out and OnTimer gets called. This blows up on line 193 when m_pPane is dereferenced. Anyone else experience this?

I have not experienced this but it is possible. If the timing is just right and the CloseWindow is called after a timer message is posted to the window then the OnTimer will fire with the m_pPane member already cleared. I have made a couple of modifications to the AutoHidePane/Wnd classes to smooth out the animation and get rid of the quick "flash" of the background when docking a hidden pane via the "hide/dock" button. Incidentally this also fixes your issue because I use m_pPane == 0 to detect when the CXTPDockingPaneAutoHideWnd is supposed to delay close. Oleg told me that the animation mods I sent in were merged into the toolkit source. So they are safe to use. The flash fix is new so no verdict on that yet. I am attaching the modified files (4) CXTPDockingPaneManager & CXTPDockingPaneAutoHidePanel both .h & .cpp. DiffReport on changes and a short description of the mods. |
