gtk.ToggleAction Properties

"current-value"Read-WriteThe value property of the currently active member of the group to which this action belongs. This property is available in GTK+ 2.10 and above.
"group"WriteSets a new group for a radio action. This property is available in GTK+ 2.4 and above
"value"Read-WriteThe value is an arbitrary integer which can be used as a convenient way to determine which action in the group is currently active in an "activate" or "changed" signal handler. See the get_current_value() and the gtk.ActionGroup.add_radio_actions() methods for convenient ways to get and set this property. This property is available in GTK+ 2.4 and above

Description

Note

This object is available in PyGTK 2.4 and above.

A gtk.RadioAction is a subclass of gtk.ToggleAction and similar to gtk.RadioMenuItem. A number of radio actions can be linked together so that only one may be active at any one time.

Constructor

    gtk.RadioAction(name, label, tooltip, stock_id, value)

name :

A unique name for the action

label :

The label displayed in menu items and on buttons

tooltip :

A tooltip for this action

stock_id :

The stock icon to display in widgets representing this action

value :

A unique integer value that get_current_value() should return if this action is selected.

Returns :

a new gtk.RadioAction

Note

This constructor is available in PyGTK 2.4 and above.

Creates a new gtk.RadioAction object suing the properties specified by: name, label, tooltip, stock_id and value. To add the action to a gtk.ActionGroup and set the accelerator for the action, call the gtk.ActionGroup.add_action_with_accel().

Methods

gtk.RadioAction.set_group

    def set_group(group)

group :

another gtk.RadioAction or None

Note

This method is available in PyGTK 2.4 and above.

The set_group() method sets the radio group for the radio action to the same group as the gtk.RadioAction specified by group i.e. the radio action joins the group.

In PyGTK 2.6.2 and above, if group is None the radio action is removed from its current group.

gtk.RadioAction.get_group

    def get_group()

Returns :

a list containing the radio actions in the group or None

Note

This method is available in PyGTK 2.4 and above.

The get_group() method returns a list containing the group that the radio action belongs to or None if the radio action is not part of a group.

gtk.RadioAction.get_current_value

    def get_current_value()

Returns :

The value of the currently active group member

Note

This method is available in PyGTK 2.4 and above.

The get_current_value() method returns the "value" property of the the currently active member of the group that the radio action belongs to.

Signals

The "changed" gtk.RadioAction Signal

    def callback(radioaction, current, user_param1, ...)

radioaction :

the radioaction that received the signal

current :

the currently active gtk.RadioAction in the group

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

Note

This signal is available in GTK+ 2.4 and above.

The "changed" signal is emitted on every member of a radio group when the active member is changed. The signal gets emitted after the "activate" signals for the previous and current active members.
