ToggleButton

Provided Methods

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.

Returns

whether the button is pressed

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 signal to be emitted.

is_active

true or false.

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.

group

another ToggleButton to form a group with

fn toggled(&self)

👎Deprecated: Since 4.10

Emits the ::toggled signal on the ToggleButton.

Deprecated since 4.10

There is no good reason for an application ever to call this function.

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

Emitted whenever the ToggleButton’s state is changed.

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

fn connect_group_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.
