Struct gtk4::CheckButton[][src]

pub struct CheckButton(_);
Expand description

A CheckButton places a label next to an indicator.

Example GtkCheckButtons

A CheckButton is created by calling either new() or with_label().

The state of a CheckButton can be set specifically using CheckButtonExt::set_active(), and retrieved using CheckButtonExt::is_active().

Inconsistent state

In addition to “on” and “off”, check buttons can be an “in between” state that is neither on nor off. This can be used e.g. when the user has selected a range of elements (such as some text or spreadsheet cells) that are affected by a check button, and the current values in that range are inconsistent.

To set a CheckButton to inconsistent state, use CheckButtonExt::set_inconsistent().

Grouping

Check buttons can be grouped together, to form mutually exclusive groups - only one of the buttons can be toggled at a time, and toggling another one will switch the currently toggled one off.

Grouped check buttons use a different indicator, and are commonly referred to as radio buttons.

Example GtkCheckButtons

To add a CheckButton to a group, use CheckButtonExt::set_group().

CSS nodes

checkbutton[.text-button]
├── check
╰── [label]

A CheckButton has a main node with name checkbutton. If the property::CheckButton::label property is set, it contains a label child. The indicator node is named check when no group is set, and radio if the checkbutton is grouped together with other checkbuttons.

Accessibility

CheckButton uses the AccessibleRole::Checkbox role.
