Trait containing all ToggleButton methods.

Required Methods§

source

fn is_active(&self) -> bool

Queries a ToggleButton and returns its current state.

Returns true if the toggle button is pressed in and false if it is raised.

fn set_active(&self, is_active: bool)

Sets the status of the toggle button.

Set to true if you want the ToggleButton to be “pressed in”, and false to raise it.

If the status of the button changes, this action causes the [toggled][struct@crate::GtkToggleButton#toggled] signal to be emitted.

fn set_group(&self, group: Option<&impl IsA<ToggleButton>>)

Adds @self_ to the group of @group.

In a group of multiple toggle buttons, only one button can be active at a time.

Setting up groups in a cycle leads to undefined behavior.

Note that the same effect can be achieved via the Actionable API, by using the same action with parameter type and state type ‘s’ for all buttons in the group, and giving each button its own target value.
