ShowPane bug in 13.2.1

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

   I know for sure that there is a bug in the Docking Pane logic. Please look at this before releasing the next version. (I have no time creating a full sample at the moment.)

1) Create panes A and B.
2) Hide pane A. Disable pane A.
4) Create layout B' (only B visible).
5) Show pane A. Enable pane A. Hide pane B. Disable pane B.
6) Create layout A' (only pane A visible).
7) Load layout A' (pane A is created).

Pane A is visible, B is hidden (with no window attached). Now I want to show B!

paneManager.ShowPane(B); // Generates XTPWM_DOCKINGPANE_NOTIFY message!

LRESULT CMainFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{
    if (wParam == XTP_DPN_SHOWWINDOW)
    {
        CXTPDockingPane* pPane = (CXTPDockingPane*)lParam;
        if (!pPane->IsValid()) // Pane B is marked as valid, which is wrong!
        {
             // Window of B is never created!
        }
    }
}

I'm not sure exactly how this is possible, but it only happens when creating and loading pane layouts!

A workaround is to pre-create the pane window in OnCreate(), but that is not a good approach!
