Detailed Description¶
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
QAction
instances are created withaddAction()
or existing actions are added to a toolbar withaddAction()
. 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
QToolButton
as a toggle button (seesetCheckable()
).
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 aQToolBar
. Change it withsetAutoRaise()
.A tool button’s icon is set as
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
setToolButtonStyle()
andsetIconSize()
. When used inside aQToolBar
in aQMainWindow
, the button automatically adjusts toQMainWindow
‘s settings (seesetToolButtonStyle()
andsetIconSize()
). Instead of an icon, a tool button can also display an arrow symbol, specified witharrowType
.A tool button can offer additional choices in a popup menu. The popup menu can be set using
setMenu()
. UsesetPopupMode()
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 timeout is style dependent, seeSH_ToolButton_PopupDelay
.
Qt Assistant’s toolbar contains tool buttons that are associated with actions used in other parts of the main window.

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 dependent, see
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 listQToolButton.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.
