## 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.

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.
