Detailed Description

The PySide.QtGui.QToolButton class provides a quick-access button to commands or options, usually used inside a PySide.QtGui.QToolBar .

A tool button is a special button that provides quick-access to specific commands or options. As opposed to a normal command button, a tool button usually doesn’t show a text label, but shows an icon instead.

Tool buttons are normally created when new PySide.QtGui.QAction instances are created with QToolBar.addAction() or existing actions are added to a toolbar with QToolBar.addAction() . It is also possible to construct tool buttons in the same way as any other widget, and arrange them alongside other widgets in layouts.

One classic use of a tool button is to select tools; for example, the “pen” tool in a drawing program. This would be implemented by using a PySide.QtGui.QToolButton as a toggle button (see setToggleButton() ).

PySide.QtGui.QToolButton supports auto-raising. In auto-raise mode, the button draws a 3D frame only when the mouse points at it. The feature is automatically turned on when a button is used inside a PySide.QtGui.QToolBar . Change it with PySide.QtGui.QToolButton.setAutoRaise() .

A tool button’s icon is set as PySide.QtGui.QIcon . This makes it possible to specify different pixmaps for the disabled and active state. The disabled pixmap is used when the button’s functionality is not available. The active pixmap is displayed when the button is auto-raised because the mouse pointer is hovering over it.

The button’s look and dimension is adjustable with PySide.QtGui.QToolButton.setToolButtonStyle() and PySide.QtGui.QAbstractButton.setIconSize() . When used inside a PySide.QtGui.QToolBar in a PySide.QtGui.QMainWindow , the button automatically adjusts to PySide.QtGui.QMainWindow ‘s settings (see QMainWindow.setToolButtonStyle() and QMainWindow.setIconSize() ). Instead of an icon, a tool button can also display an arrow symbol, specified with PySide.QtGui.QToolButton.arrowType() .

A tool button can offer additional choices in a popup menu. The popup menu can be set using PySide.QtGui.QToolButton.setMenu() . Use PySide.QtGui.QToolButton.setPopupMode() to configure the different modes available for tool buttons with a menu set. The default mode is DelayedPopupMode which is sometimes used with the “Back” button in a web browser. After pressing and holding the button down for a while, a menu pops up showing a list of possible pages to jump to. The default delay is 600 ms; you can adjust it with setPopupDelay() .

PySide.QtGui.QToolButton.ToolButtonPopupMode

Describes how a menu should be popped up for tool buttons that has a menu set or contains a list of actions.

Constant Description
QToolButton.DelayedPopup After pressing and holding the tool button down for a certain amount of time (the timeout is style dependant, see QStyle.SH_ToolButton_PopupDelay ), the menu is displayed. A typical application example is the “back” button in some web browsers’s tool bars. If the user clicks it, the browser simply browses back to the previous page. If the user presses and holds the button down for a while, the tool button shows a menu containing the current history list
QToolButton.MenuButtonPopup In this mode the tool button displays a special arrow to indicate that a menu is present. The menu is displayed when the arrow part of the button is pressed.
QToolButton.InstantPopup The menu is displayed, without delay, when the tool button is pressed. In this mode, the button’s own action is not triggered.
