Thanks you're right :( ts indeed bug in our code.

 

Can you please patch CXTPDockingPaneTabbedContainer::OnCaptionButtonDown method and add

 

InternalAddRef();, InternalRelease(); calls:

 

 

 

BOOL CXTPDockingPaneTabbedContainer::OnCaptionButtonDown(CXTPDockingPaneCaptionButton* pButton)
{
 switch (pButton->GetID())
 {
 case XTP_IDS_DOCKINGPANE_MENU:
  if (m_pSelectedPane)
  {
   InternalAddRef();

   CXTPDockingPaneManager* pManager = GetDockingPaneManager();
   XTP_DOCKINGPANE_CLICK menu;

   menu.rcExclude = pButton->GetRect();
   ClientToScreen(&menu.rcExclude);

   menu.pt = CPoint(menu.rcExclude.left, menu.rcExclude.bottom);
   menu.pPane = m_pSelectedPane;
   pButton->m_bPressed = TRUE;
   Invalidate(FALSE);

   pManager->NotifyOwner(XTP_DPN_PANEMENUCLICK, (LPARAM)&menu);

   pButton->m_bPressed = FALSE;
   if (m_hWnd) Invalidate(FALSE);

   InternalRelease();
  }
  return TRUE;

 }
 return FALSE;
}

 

rebuild dll and your application after.

 

Thank you

 

When I open the pane menu (which shown via the XTPWM_DOCKINGPANE_NOTIFY message with wParam  XTP_DPN_PANEMENUCLICK ) and select 'AutoHide' the ToggleAutoHide function is called.

So fare this is ok but when I make the pane visible (autohide is still active) and select 'AutoHide' from that same menu again the application crashes. Using the pin / unpin works OK but via the menu the ToggleAutoHide does not work.

 

I want to implement the same menu in my own application but due to this bug I have to remove the AutoHide function from the menu or make a workaround for this bug.

 

Does anybody know how to make the ToggleAutoHide call function correctly?
