Detailed Description

Toolbar buttons are added by adding actions , using addAction() or insertAction() . Groups of buttons can be separated using addSeparator() or insertSeparator() . If a toolbar button is not appropriate, a widget can be inserted instead using addWidget() or insertWidget() . Examples of suitable widgets are QSpinBox , QDoubleSpinBox , and QComboBox . When a toolbar button is pressed, it emits the actionTriggered() signal.

A toolbar can be fixed in place in a particular area (e.g., at the top of the window), or it can be movable between toolbar areas; see setMovable() , isMovable() , allowedAreas() and isAreaAllowed() .

When a toolbar is resized in such a way that it is too small to show all the items it contains, an extension button will appear as the last item in the toolbar. Pressing the extension button will pop up a menu containing the items that do not currently fit in the toolbar.

When a QToolBar is not a child of a QMainWindow , it loses the ability to populate the extension pop up with widgets added to the toolbar using addWidget() . Please use widget actions created by inheriting QWidgetAction and implementing createWidget() instead.
