Detailed Description

QActionGroup is a base class for classes grouping classes inhheriting QAction objects together.

In some situations it is useful to group QAction objects together. For example, if you have a Left Align action, a Right Align action, a Justify action, and a Center action, only one of these actions should be active at any one time. One simple way of achieving this is to group the actions together in an action group, inheriting QActionGroup .

class ExclusionPolicy

This enum specifies the different policies that can be used to control how the group performs exclusive checking on checkable actions.

Constant

Description

QActionGroup.ExclusionPolicy.None

The actions in the group can be checked independently of each other.

QActionGroup.ExclusionPolicy.Exclusive

Exactly one action can be checked at any one time. This is the default policy.

QActionGroup.ExclusionPolicy.ExclusiveOptional

At most one action can be checked at any one time. The actions can also be all unchecked.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property enabledᅟ: bool

This property holds whether the action group is enabled.

Each action in the group will be enabled or disabled unless it has been explicitly disabled.

setEnabled()

Access functions:
property exclusionPolicyᅟ: QActionGroup.ExclusionPolicy

This property holds This property holds the group exclusive checking policy.

If exclusionPolicy is set to Exclusive, only one checkable action in the action group can ever be active at any time. If the user chooses another checkable action in the group, the one they chose becomes active and the one that was active becomes inactive. If exclusionPolicy is set to ExclusionOptional the group is exclusive but the active checkable action in the group can be unchecked leaving the group with no actions checked.

Access functions:
property visibleᅟ: bool

This property holds whether the action group is visible.

Each action in the action group will match the visible state of this group unless it has been explicitly hidden.

setEnabled()

Access functions:
__init__(parent)
Parameters:

parent – QObject

Constructs an action group for the parent object.

The action group is exclusive by default. Call setExclusive (false) to make the action group non-exclusive. To make the group exclusive but allow unchecking the active action call instead setExclusionPolicy ( ExclusiveOptional )

actions()
Return type:

.list of QAction

Returns the list of this groups’s actions. This may be empty.

addAction(a)
Parameters:

a – QAction

Return type:

QAction

Adds the action to this group, and returns it.

bool

Getter of property visibleᅟ .
