/**

|
* SECTION:gtkaction
|
|
* @Short_description: An action which can be triggered by a menu or toolbar item
|
|
* @Title: GtkAction
|
|
* @See_also: #GtkActionGroup, #GtkUIManager, #GtkActivatable
|
|
*
|
|
* Actions represent operations that the user can be perform, along with
|
|
* some information how it should be presented in the interface. Each action
|
|
* provides methods to create icons, menu items and toolbar items
|
|
* representing itself.
|
|
*
|
|
* As well as the callback that is called when the action gets activated,
|
|
* the following also gets associated with the action:
|
|
* <itemizedlist>
|
|
* <listitem><para>a name (not translated, for path lookup)</para></listitem>
|
|
* <listitem><para>a label (translated, for display)</para></listitem>
|
|
* <listitem><para>an accelerator</para></listitem>
|
|
* <listitem><para>whether label indicates a stock id</para></listitem>
|
|
* <listitem><para>a tooltip (optional, translated)</para></listitem>
|
|
* <listitem><para>a toolbar label (optional, shorter than label)</para></listitem>
|
|
* </itemizedlist>
|
|
* The action will also have some state information:
|
|
* <itemizedlist>
|
|
* <listitem><para>visible (shown/hidden)</para></listitem>
|
|
* <listitem><para>sensitive (enabled/disabled)</para></listitem>
|
|
* </itemizedlist>
|
|
* Apart from regular actions, there are <link linkend="GtkToggleAction">toggle
|
|
* actions</link>, which can be toggled between two states and <link
|
|
* linkend="GtkRadioAction">radio actions</link>, of which only one in a group
|
|
* can be in the "active" state. Other actions can be implemented as #GtkAction
|
|
* subclasses.
|
|
*
|
|
* Each action can have one or more proxy widgets. To act as an action proxy,
|
|
* widget needs to implement #GtkActivatable interface. Proxies mirror the state
|
|
* of the action and should change when the action's state changes. Properties
|
|
* that are always mirrored by proxies are #GtkAction:sensitive and
|
|
* #GtkAction:visible. #GtkAction:gicon, #GtkAction:icon-name, #GtkAction:label,
|
|
* #GtkAction:short-label and #GtkAction:stock-id properties are only mirorred
|
|
* if proxy widget has #GtkActivatable:use-action-appearance property set to
|
|
* %TRUE.
|
|
*
|
|
* When the proxy is activated, it should activate its action.
