I am trying to create tooltips for the panes of a reasonably standard CMFCStatusBar. I would like Balloon tooltips, but the rectangular ones will do if "push comes to shove". My biggest problem is trying to find a decent explanation for the override arguments. Microsoft marks a lot of the class members:
"This topic is included for completeness. For more detail see the source code located in the VC\atlmfc\src\mfc folder of your Visual Studio installation.'
Frankly, I did not buy the product so that I have to spend the time reverse engineering Microsoft's sketchy at best examples. It is not like Microsoft is so cash poor as to not be able to do a complete job! Rant over!
I do have a valid pointer to the Status Bar.
A good example of the frustration is with CMFCToolTipCtrl::OnDrawDescription. I understand what p_DC is and where it comes from however, CRect rect is still a mystery. I am assuming that it is the rectangle containing the text, but do I specify the rectangle size that I want, or does the class do or a little of both? Who or what positions the text block in the overall tool tip when drawing takes place?
BOOL bCalcOnly is another mystery. I have figured out that OnDrawDescription is called twice, once with bCalcOnly == TRUE and once with it == FALSE. I also figured out that bCalcOnly == TRUE draws the text; == FALSE doesn't. Do I have to do something else?
The arguments are marked [in]; is that supposed to mean that I must supply something?
If anyone out there knows of a link that has a decent example, or an article that has a better detail of the class members, it would be greatly appreciated.
Thanks,
Barry
