In this example, we show a tooltip for the PyQt4 widgets.

QtGui.QToolTip.setFont (Qtgui.qfont (' Sansserif ', 10))

This static method sets a font used to render tooltips. We use a 10px sansserif font.

Self.settooltip (' This is a <b>QWidget</b> widget ')

To create a ToolTip, we call the setTooltip() method. We can also use rich text formatting.

BTN = Qtgui.qpushbutton (' Button ', self) btn.settooltip (' This is a <b>QPushButton</b> widget ')

We Create a button widget and set a ToolTip for it.

Btn.resize (Btn.sizehint ()) Btn.move (50, 50)       

The button is a being resized and moved on the window. The sizeHint() method gives a recommended size for the button.
