These three facts are related and happen, because Fl_Tooltip::enter() is called only, if the belowmouse() widget has changed, i.e. when there would have been a FL_ENTER and/or FL_LEAVE event as well. This has obviously been intended (fewer events to handle in Fl_Tooltip.cxx), but may be wrong ? Case 1: The tooltip pops up while the mouse moves: IMHO, this is a bug and should be fixed. I'm looking what should be done, if ... - but I'd like to read your comments about this. Case 2: The tooltip stays visible, while the mouse moves. I tested this with other applications, and this seems to be common behavior (at least with some applications under Windows). The tooltip disappears, if the mouse leaves the widget or enters the tooltip area itself. A good test candidate is thunderbird, because it has big buttons (at least in my setup). There is also a timeout (about 5 seconds). Case 3: The tooltip is dismissed, if the tooltip area itself is touched by mouse movement and reappears immediately or after a short (hoverdelay) timeout. Once case 1 would be fixed, this would change, too (in a way that the tooltip would reappear only if the mouse stops moving). My questions and my opinions are: 1) Should case 1 be fixed? +1 2) Should there be a timeout to remove the tooltip (5 sec. or ...?) +1 (5 seconds) 3) Should it really reappear, if the mouse moves without leaving the widget (this could also be a group or a complete window) ? +/-0: I don't know. Thunderbird pops up the tooltip again after the mouse stops moving. Your comments are welcome.
