MDI forms- keep panes in form

Hi Aaron:

Here are mods to MDIPanes sample so that when an MDI window is deactivated it hides its floating pane and shows it when re-activated. If the pane is not floating leaves it as is.

Not quite the restriction of not being able to float a pane but from what you described it should do the trick.

I tried these mods on the MDIPane sample app:

1. In CChildFrame::OnDockingPaneNotify after the line

pPane->Attach(&m_wndPropertyGrid);

pPane->SetOptions(xtpPaneNoCloseable);

This will remove the x from the docked pane and prevent it from closing. When floating the X is still there but does nothing.

2. Declare in ChildFrm.h

afx_msg void OnMDIActivate(BOOL bActivate, CWnd* pActivateWnd, CWnd* pDeactivateWnd);

3. In ChildFrm.cpp Add to the message map

ON_WM_MDIACTIVATE()

4. In ChildFrm.cpp Add the OnMDIActivate function:

void CChildFrame::OnMDIActivate(BOOL bActivate, CWnd* pActivateWnd, CWnd* pDeactivateWnd) 
{
    CMDIChildWnd::OnMDIActivate(bActivate, pActivateWnd, pDeactivateWnd);
 
    if (bActivate && m_paneManager.IsPaneClosed(IDR_PANE_PROPERTIES))
    {
         m_paneManager.ShowPane(IDR_PANE_PROPERTIES); 
    }
    else if  (m_paneManager.FindPane(IDR_PANE_PROPERTIES)->IsFloating( ))
    {
         m_paneManager.ClosePane(IDR_PANE_PROPERTIES); 
    }
}
