void QWidget::setStyle ( QStyle style  )  [inherited]

Sets the widget's GUI style to style. The ownership of the style object is not transferred.

If no style is set, the widget uses the application's style, QApplication::style() instead.

Setting a widget's style has no effect on existing or future child widgets.

This function is particularly useful for demonstration purposes, where you want to show Qt's styling capabilities. Real applications should avoid it and use one consistent GUI style instead.

Qt style sheets are currently not supported for custom QStyle subclasses. We plan to address this in some future release.
