Detailed Description

The QToolBar class provides a movable panel that contains a set of controls.

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 (isMovable()) between toolbar areas; see 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 does not currently fit in the toolbar. Note that only action based items will be shown in the menu. If only non-action based items are to appear in the extension menu (e.g. a QSpinBox), the extension button will appear as usual, but it will be disabled to indicate that some items in the toolbar are currently not visible.

See also QToolButton.
