Hi,
i need yor help please:

I want to handle XTP_DPN_PANEMENUCLICK. But when the lParam in this case doesn't point to a valid CXTPDockingPane.
What is wrong or how can i get the pane who sends the message?




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

    switch ((int)wParam)
    {
       case XTP_DPN_SHOWWINDOW:
          // here pPane is valid
          break;

       case XTP_DPN_PANEMENUCLICK:
          // here pPane is invalid
          break;
    }
}

because lParam is XTP_DOCKINGPANE_CLICK pointer.

XTP_DOCKINGPANE_CLICK* pClick = (XTP_DOCKINGPANE_CLICK*)lParam;

lParam depends on wParam value.

move CXTPDockingPane* pPane = (CXTPDockingPane*)lParam; to scope of case XTP_DPN_SHOWWINDOW.

Yes, sorry was not documented :(

Use it as:

XTP_DOCKINGPANE_CLICK* pClick = (XTP_DOCKINGPANE_CLICK*)lParam;

CXTPDockingPane* pPane = pClick->pPane.

 

 

 

ps. structure declaration

struct XTP_DOCKINGPANE_CLICK
{
 CXTPDockingPane* pPane;
 CPoint pt;
 CRect rcExclude;
};
