Provided Methods

fn action_name(&self) -> Option<GString>

Gets the action name for @self.

Returns

the action name

fn action_target_value(&self) -> Option<Variant>

Gets the current target value of @self.

Returns

the current target value

fn set_action_name(&self, action_name: Option<&str>)

Specifies the name of the action with which this widget should be associated.

If @action_name is None then the widget will be unassociated from any previous action.

Usually this function is used when the widget is located (or will be located) within the hierarchy of a ApplicationWindow.

Names are of the form “win.save” or “app.quit” for actions on the containing ApplicationWindow or its associated Application, respectively. This is the same form used for actions in the gio::Menu associated with the window.

action_name

an action name

fn set_action_target_value(&self, target_value: Option<&Variant>)

Sets the target value of an actionable widget.

If @target_value is None then the target value is unset.

The target value has two purposes. First, it is used as the parameter to activation of the action associated with the Actionable widget. Second, it is used to determine if the widget should be rendered as “active” — the widget is active if the state is equal to the given target.

Consider the example of associating a set of buttons with a gio::Action with string state in a typical “radio button” situation. Each button will be associated with the same action, but with a different target value for that action. Clicking on a particular button will activate the action with the target of that button, which will typically cause the action’s state to change to that value. Since the action’s state is now equal to the target value of the button, the button will now be rendered as active (and the other buttons, with different targets, rendered inactive).

target_value

a glib::Variant to set as the target value

fn set_detailed_action_name(&self, detailed_action_name: &str)

Sets the action-name and associated string target value of an actionable widget.

@detailed_action_name is a string in the format accepted by gio::Action::parse_detailed_name().

detailed_action_name

the detailed action name

fn connect_action_name_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

fn connect_action_target_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
