Tooltips and toolbars in MFC, or: why my life sucks right now.

felisandria · 2004-06-14T10:01:08

I''m working on a relatively complex little app that has 3 splitter windows. The window on the far right has a toolbar in the edge of its frame that I do border negotiations to accomodate the viewing of. The window on the far right is a fram with 6 views that take turns being shown, maximized. Although I can get command messages from the toolbar docked at the right edge of the frame, I can''t get the text down at the bottom or the tooltip to show for the toolbar. The parent window is a CFrameWnd derivative so it should do it natively. I already tried overriding TTN_NEEDTEXT notification everywhere I can think of... it never gets called at all. Has anyone else had problems with getting tooltips to show in toolbars that are docked to subframes in splitter windows, or is it just me? Also, my mainframe toolbar will show the tooltips for the 3 report views I have, but not for the graphical views when they''re the current active windows on the right. I''ve tried notification overrides there too, no luck. I''m starting to wonder if it isn''t that the graphical views have a timer and that might interfere with the OnIdle while a graphical is the active view, but that really shouldn''t be the case. I''m baffled. Suggestions? -fel

OK, a simple, pure Win32 (absolutely no MFC) example demonstrating tooltips on the main window, a child dialog, a check box, and a button is up. Source code and an executable.

Just click go to my main homepage, and go to the download section. If anyone is interested in any other Win32 code examples, just ask.

These &*("ing tooltips do my head in. Now the checkboxes and buttons work, but the labels dont. Presumably something to do with labels forwarding all messages to the parent window.....

Thanks anyway, I should be able to get this working now.... If I can just figure out how to fix this problem cleanly.

I had a problem similar to Felisandria''s one. My TTN_NEEDTEXT handler in CFrameWnd-derived class was not called after mouse cursor had been moved upon a toolbar button.

The solution was to write
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, YourHandlerName)
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, YourHandlerName)
instead of
ON_NOTIFY_EX(TTN_NEEDTEXT, 0, YourHandlerName)
in CFrameWnd-derived class'' message map.

What sometimes helps is to have a PreTranslateMessage and call RelayEvent for the tooltip control.

quote:Original post by felisandria
I liberally sprinkled TTN_NEEDTEXT handlers throughout every view and frame that this toolbar gets anywhere near, and none of them get hit, at all *sigh*

I don''t know where it''s routing, or even IF it''s routing. Command messages work fine, tooltip notification is apparently nonexistent.

Let''s get back on topic - it seems your thread has been hijacked; I am assuming that you have covered all the obvious things:

1) Creating the toolbar with TBSTYLE_TOOLTIPS - the toolbar should then create it''s own tooltip control so you shouldn''t have to worry about message routing etc.

2) You have called EnableToolTips

3) You have handlers for TTN_NEEDTEXTA and TTN_NEEDTEXTW

Failing that I don''t know what could be the problem without seeing the code.

I eventually fixed that... don''t really remember what I did... actually I don''t even work at that company anymore hehe. Original post is over 2 years old.

So, needless to say, hijacking is not a big deal at this time.

we also suffer from this tooltip problem.
there was a groupbox, and some bitmap button within it.
the real suck is if the TAB ORDER of the group box is less than that of the button, then the button never will get the TTN_NEEDTEXT message... the groupbox silently swallows it...
nightmare MFC...
