Custom Tooltip regions on QWidget
Is there a standardized way if I have a QWidget and would like to have several custom regions (defined by QRect), where hovering over each one triggers a different tooltip?
You should override the event() function and look for the QEvent::ToolTip event. When you get that one, cast the QEvent to a QHelpEvent and get the mouse position, match that to your areas and show the appropriate tool tip.
From the "documentation":http://doc.trolltech.com/4.7-snapshot/qtooltip.html for QToolTip...
bq. It is also possible to show different tool tips for different regions of a widget, by using a QHelpEvent of type QEvent::ToolTip. Intercept the help event in your widget's event() function and call QToolTip::showText() with the text you want to display. The Tooltips example illustrates this technique.
EDIT: So, pretty much what Franzk said above...
Thanks for the (tool)tip.
