Implementing Tooltips for Menus

Environment: VC6, NT4 SP3

Well, as you see the new Win2000 you may have wondered how to get those nice tool tips for menu bars in your own apps. Then you found the right place !

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 !

    I have implemented your code in to my project and have run across an interesting problem. I have made the tool tips so that the user can enable or disable them. On a customer's Win 98 machine, if the tool tips are enabled, the only way you can select an item from the menu is to keep the left mouse button depressed. It will show the tool tip for each menu item and then when you release the left mouse button, the selected item will be executed. If you do not hold the left mouse button down, the menu will appear and always select the first menu item. If you disable the tool tip option, then everything works like normal.

    Any ideas!?

  • Well, It's working pretty good

    Thank you for your work.

  • This code is wrong and will never work

    As soon as popup menu jumps out of the mainframe area
    the function stops working!
    Anyway, thanks for idea.
