Destroy pane on closing

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I would like to destroy a pane if the user closes it. So far I had no success:

LRESULT CMainFrame::OnDockingPaneNotify (WPARAM wParam, LPARAM lParam)
{
   CXTPDockingPane *pPane = (CXTPDockingPane *) lParam;

   switch (wParam)
   {
   case XTP_DPN_CLOSEPANE:
      m_paneManager.DestroyPane (pPane);
      1) break;
      2) return XTP_ACTION_NOCLOSE;
   }

   return 0;
}

1) Causes a crash because the toolkit trys to close a destroyed pane after the event handler returns.

2) The pane is beeing destroyed and the toolkit doesn't try to close the pane anymore, but the pane isn't really destroyed. I've attached a view (AttachView) to the pane which isn't destroyed when calling DestroyPane. The view will be destroyed when the main frame is beeing closed.

In AttachView I can pass the parent window, but unfortunately I can not set the pane as the parent: cannot convert parameter 1 from 'class CXTPDockingPane *' to 'class CWnd *'

	Hi, You need XTP_ACTION_NOCLOSE + manually destroy child pane. Something like: if (pPane->GetChild()) pPane->GetChild()->DestroyWindow(); m_paneManager.DestroyPane (pPane); return XTP_ACTION_NOCLOSE;

	Thanks, pPane->GetChild()->DestroyWindow(); works. But the expected behaviour is if you destroy a window it's childs are destroyed too, which is not the case for the panes.

	Hi, It is not expected behavior for panes. For example if developer want to change layout he can destroy pane and create it again and it will not destory child. Or like in panes sample want to change from some "debug" to "Edit" layout.
