Drawing problems

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

   I've got a standard SDI MFC app that I'm using two docking panes with.
When these are docked to the left and then hidden, it seems to have trouble drawing them correctly on expanding, once it gets to a certain point it flickers and misses part of the dock + view.
I've attached a picture of what I'm talking about. Weirdly, if I dock them on the bottom or top it seems to work ok.

	Hello, Try adding the WS_CLIPCHILDREN style to your CMainFrame class, for example: BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) { if( !CFrameWnd::PreCreateWindow(cs) ) return FALSE; // TODO: Modify the Window class or styles here by modifying // the CREATESTRUCT cs cs.style \|= WS_CLIPCHILDREN\|WS_CLIPSIBLINGS; return TRUE; } Please let me know if this helps. Cheers, Codejock Support

	That worked great, thanks. Incidentally, I'm having trouble with a context menu in the docking pane (well the view that's attached to one anyway). It seems that I can only provide implementations for the ON_COMMAND or ON_UPDATE_COMMAND_UI handlers, not both. I was wondering if you might be able to suggest any reasons why this might be happening? Thanks again, Jamie Edited by jamiei

	I tring to add context menu in "Advanced" sample void CHeroesView::OnContextMenu(CWnd* pWnd, CPoint point) { CMenu mnu; mnu.LoadMenu(IDR_MAINFRAME); CXTPCommandBars::TrackPopupMenu(&mnu, 0, point.x, point.y, this); } All work as expected. How do you call the menu?

	Oleg, Sorry for not replying sooner. I tried using your code above, but for some reason my ON_COMMAND_UPDATE handler isn't being called. However, I was using the following and it almost worked: CMenu menu; menu.LoadMenu(IDR_MONITORS_MENU); CMenu* pSubMenu = menu.GetSubMenu(0); // Display the menu at the current mouse location. There's a "bug" // (Microsoft calls it a feature) in Windows 95 that requires calling // SetForegroundWindow. To find out more, search for Q135788 in MSDN. // CPoint point; GetCursorPos(&point); ::SetForegroundWindow(m_hWnd); //ClientToScreen(&point); GetCursorPos(&m_ptCursorPos); CXTPFrameWnd* pFrameWnd = (CXTPFrameWnd*)AfxGetMainWnd(); ASSERT_VALID(pFrameWnd); CXTPCommandBars::TrackPopupMenu(pSubMenu, 0, point.x, point.y, this); ::PostMessage(m_hWnd, WM_NULL, 0, 0); menu.DestroyMenu(); I'm using this context menu in a TreeView derived class (within a docking pane). If a user highlights a tree item it should enable one of the menu options. Although this works (enabling/disabling), if I then click on the item to action the handler, it doesn't do anything and I get a warning in the debug window: "Warning: not executing disabled command 39776" Is it something odd to do with the cursor being updated when I click on the item and the update handler's called again, and disables it?
