It's a matter of when you're destroying the pane. Try it if you're processing 'XTPN_CLOSE_PANE' notification - it will fail.]]> Thu, 06 Jan 2005 02:55:09 +0000 http://forum.codejock.com/forum_posts.asp?TID=1577&PID=4624&title=destroying-a-pane-instead-of-closing#4624 <![CDATA[Destroying a pane instead of closing : Thats kind of strange that you...]]> http://forum.codejock.com/forum_posts.asp?TID=1577&PID=4615&title=destroying-a-pane-instead-of-closing#4615 Author: spike

Thats kind of strange that you say the pointer is in use after the Close. This is my code which seems to work fine.

FOREACH_ARRAY( m_arrOptionalPaneID, i )
  {
   CXTPDockingPane *pPane = m_pPaneManager->FindPane( m_arrOptionalPaneID );
   m_pPaneManager->ClosePane( m_arrOptionalPaneID );

   if( pPane )
   {
    m_pPaneManager->DestroyPane( pPane );
   }
  }

Edit: Actually they use  SAFE_PTR call, which probly validates that the pointer. So it should be safe, nevertheless you have your solution.

Thanks for your help !

It works fine this way :

LRESULT FileBrowserFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{
..
..
else if ( wParam == XTP_DPN_ACTION )
    {
    XTP_DOCKINGPANE_ACTION *action = XTP_DOCKINGPANE_ACTION*)lParam;

    if ( action->action == xtpPaneActionClosed )
      GetDockingPaneManager()- >DestroyPane( action->pPane );

    return TRUE;
    }

I tried that of course too. But the pointer to the pane is still in use after the notification :

void CXTPDockingPaneManager::ClosePane(CXTPDockingPane* pPane)
{
     if (pPane == NULL) return;

     if (m_pSite->SendMessage(XTPWM_DOCKINGPANE_NOTIFY, XTP_DPN_CLOSEPANE, (LPARAM)pPane) == XTP_ACTION_NOCLOSE)
           return;
     
     SAFE_CALLPTR(pPane->m_pPare ntContainer, RemovePane(pPane));     
}

Well then you should call DestroyPane in the XTPN_CLOSE_PANE (sp?) notifcation in OnDockingPaneNotify.]]> Wed, 22 Dec 2004 21:12:54 +0000 http://forum.codejock.com/forum_posts.asp?TID=1577&PID=4509&title=destroying-a-pane-instead-of-closing#4509 <![CDATA[Destroying a pane instead of closing : Hello, how can I destroy the...]]> http://forum.codejock.com/forum_posts.asp?TID=1577&PID=4507&title=destroying-a-pane-instead-of-closing#4507 Author: Alex G.

Hello,

how can I destroy the pane instead of closing it ?

Of course I know about the method DestroyPane in class
DockingPaneManager...

Assume I want to destroy the pane after the user depressed the pane's close button.

Thanks in advance !

Alex
