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]

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

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("");
