I have a CXTPDockingPane in my application and a menu item to turn the pane on and off - the menu item is ticked to indicate when the pane is visible. If I close the pane via my menu event handler, I do the following:

m_paneManager.DestroyPane(pane);
m_MTIClientWnd.Refresh();

In my menu OnUpdate method, I test the following to tick the menu item:

CXTPDockingPane *pane = m_paneManager.FindPane(IDGT_PANE_PROJBROWSER);
if ( (pane != NULL) && (!pane->IsHidden()) )
pCmdUI->SetCheck(true);
else
pCmdUI->SetCheck(false);

The problem is when the user closes the pane using the 'x' in the corner - the pane is closed from the screen, but the FindPane method still finds the pane, so my code still shows a tick on the menu item . Do I need to add to my OnDockingPaneNotify, if (wParam == XTP_DPN_CLOSEPANE) method to destroy the pane properly? I have tried pPane->Detach(); but this doesn't do anything. I have tried m_paneManager.DestroyPane(pPane);, but this causes a crash.

Help!!

Hi,

don't call DestroyPane if you need to show it later.

just check

if (pPane && pPane->IsClosed()) instead.

IsHidden check if pane in AutoHide Mode.

I do want to destroy the pane and I don't want it later, but if I call DestroyPane inside the OnDockingPaneNotify method, it causes a crash. How can I DestroyPane when the user clicks the 'x' in the corner of a pane?

Hello,

If you want to destroy it, you can catch Action event and check if action is xtpPaneActionClosed.
