Required Methods§
sourcefn action_name(&self) -> Option<GString>
fn action_name(&self) -> Option<GString>
sourcefn action_target_value(&self) -> Option<Variant>
fn action_target_value(&self) -> Option<Variant>
sourcefn set_action_name(&self, action_name: Option<&str>)
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
sourcefn set_action_target_value(&self, target_value: Option<&Variant>)
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
sourcefn set_detailed_action_name(&self, detailed_action_name: &str)
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
