Struct qt_gui::QHelpEvent

#[repr(C)]
pub struct QHelpEvent { /* fields omitted */ }

The QHelpEvent class provides an event that is used to request helpful information about a particular point in a widget.

C++ class: QHelpEvent.

C++ documentation:

The QHelpEvent class provides an event that is used to request helpful information about a particular point in a widget.

This event can be intercepted in applications to provide tooltips or "What's This?" help for custom widgets. The type() can be either QEvent::ToolTip or QEvent::WhatsThis.

Methods
