function eventFilter

Event filter for global tooltips.

bool GlobalFilter::eventFilter (

) override

Intercepts QEvent::ToolTip events across the application, extracts appropriate tooltip text from item views, menus, toolbars, and generic widgets, and displays a custom SBGUIToolTip. If no tooltip text is found, any visible custom tooltip is hidden and the event is passed to the base implementation.

• event The QEvent to be filtered (expected to be a QHelpEvent for tooltips).

Returns:

true if the event was handled (tooltip displayed or hidden); otherwise false.
