## Member Function Documentation

### void QToolTip::add ( QWidget * widget, const QString & text ) `[static]`

Use QWidget::setToolTip() instead.

For example, if you have code like

     tip->add(widget, text);

you can rewrite it as

     widget->setToolTip(text);

### void QToolTip::add ( QWidget * widget, const QRect & rect, const QString & text ) `[static]`

Intercept the QEvent::ToolTip events in your widget's QWidget::event() function and call QToolTip::showText() with the text you want to display. The Tooltips example illustrates this technique.

### void QToolTip::remove ( QWidget * widget ) `[static]`

Use QWidget::setToolTip() instead.

For example, if you have code like

     tip->remove(widget);

you can rewrite it as

     widget->setToolTip("");
