## Detailed Description

The QToolTip class provides tool tips (balloon help) for any widget.

The tip is a short piece of text reminding the user of the widget's function. It is drawn immediately below the given position in a distinctive black-on-yellow color combination. The tip can be any rich text formatted string.

Rich text formatted tips implictely do word breaking, unless specified differently with `<p style='white-space:pre'>`.

The simplest and most common way to set a widget's tooltip is by calling its QWidget::setToolTip() function.

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 QWidget::event() function and call QToolTip::showText() with the text you want to display. The Tooltips example illustrates this technique.

See also QWidget::toolTip, QAction::toolTip, and Tooltips Example.
