Desktop-as-a-Service Designed for Any Cloud ? Nutanix Frame
Environment: VC6, NT4 SP3
In my small demo application I implemented a very simple tooltip for menus which uses the status bar messages for its own display (informative though)
My implementation is probably quite preliminary, but it seems to work with NT 4.0, Win 98 and maybe Win 95, too.
All the changes to get the menu tip go to CMainFrame class. I first overrode both OnEnterMenuLoop and OnExitMenuLoop, furthermore OnEnterIdle and then FilterToolTipMessage. When a menu pops up, OnEnterMenuLoop is called, which then creates a WS_EX_TOPMOST style tooltip. The tooltip is updated by OnEnterIdle which passes fake WM_MOUSEMOVE messages to the tooltip using RelayEvent. I do need to override FilterToolTipMessage, because the MFC CWnd::FilterToolTipMessage does not create WS_EX_TOPMOST tooltips and therefore does NOT display the tooltip. It is important to define your own method !
Well, that4s it, I think. Just download the sample app and try it !
