Interface

AtkAction

Description [src]

interface Atk.Action : GObject.Object

AtkAction should be implemented by instances of AtkObject classes with which the user can interact directly, i.e. buttons, checkboxes, scrollbars, e.g. components which are not “passive” providers of UI information.

Exceptions: when the user interaction is already covered by another appropriate interface such as AtkEditableText (insert/delete text, etc.) or AtkValue (set value) then these actions should not be exposed by AtkAction as well.

Though most UI interactions on components should be invocable via keyboard as well as mouse, there will generally be a close mapping between “mouse actions” that are possible on a component and the AtkActions. Where mouse and keyboard actions are redundant in effect, AtkAction should expose only one action rather than exposing redundant actions if possible. By convention we have been using “mouse centric” terminology for AtkAction names.

Prerequisite

In order to implement Action, your type must inherit from GObject.

Instance methods

atk_action_do_action

Perform the specified action on the object.

atk_action_get_description

Returns a description of the specified action of the object.

atk_action_get_keybinding

Gets the keybinding which can be used to activate this action, if one exists. The string returned should contain localized, human-readable, key sequences as they would appear when displayed on screen. It must be in the format “mnemonic;sequence;shortcut”.

atk_action_get_localized_name

Returns the localized name of the specified action of the object.

atk_action_get_n_actions

Gets the number of accessible actions available on the object. If there are more than one, the first one is considered the “default” action of the object.

atk_action_get_name

Returns a non-localized string naming the specified action of the object. This name is generally not descriptive of the end result of the action, but instead names the ‘interaction type’ which the object supports. By convention, the above strings should be used to represent the actions which correspond to the common point-and-click interaction techniques of the same name: i.e. “click”, “press”, “release”, “drag”, “drop”, “popup”, etc. The “popup” action should be used to pop up a context menu for the object, if one exists.

atk_action_set_description

Sets a description of the specified action of the object.
