fn description(&self, i: i32) -> Option<GString>
fn description(&self, i: i32) -> Option<GString>
fn keybinding(&self, i: i32) -> Option<GString>
fn keybinding(&self, i: i32) -> Option<GString>
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”.
- The mnemonic key activates the object if it is presently enabled onscreen. This typically corresponds to the underlined letter within the widget. Example: “n” in a traditional “New…” menu item or the “a” in “Apply” for a button.
- The sequence is the full list of keys which invoke the action even if the relevant element is not currently shown on screen. For instance, for a menu item the sequence is the keybindings used to open the parent menus before invoking. The sequence string is colon-delimited. Example: “Alt+F:N” in a traditional “New…” menu item.
- The shortcut, if it exists, will invoke the same action without showing the component or its enclosing menus or dialogs. Example: “Ctrl+N” in a traditional “New…” menu item.
Example: For a traditional “New…” menu item, the expected return value would be: “N;Alt+F:N;Ctrl+N” for the English locale and “N;Alt+D:N;Strg+N” for the German locale. If, hypothetically, this menu item lacked a mnemonic, it would be represented by “;;Ctrl+N” and “;;Strg+N” respectively.
i
the action index corresponding to the action to be performed
Returns
the keybinding which can be used to activate
this action, or None if there is no keybinding for this action.
fn localized_name(&self, i: i32) -> Option<GString>
fn localized_name(&self, i: i32) -> Option<GString>
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.
Returns
a the number of actions, or 0 if self does not
implement this interface.
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.
For technical reasons, some toolkits cannot guarantee that the
reported action is actually ‘bound’ to a nontrivial user event;
i.e. the result of some actions via do_action() may be
NIL.
i
the action index corresponding to the action to be performed
Returns
a name string, or None if self does not
implement this interface.
