pub struct ModelButton { /* private fields */ }
Expand description

GtkModelButton is a button class that can use a GAction as its model. In contrast to ToggleButton or RadioButton, which can also be backed by a GAction via the property::Actionable::action-name property, GtkModelButton will adapt its appearance according to the kind of action it is backed by, and appear either as a plain, check or radio button.

Model buttons are used when popovers from a menu model with Popover::from_model(); they can also be used manually in a PopoverMenu.

When the action is specified via the property::Actionable::action-name and property::Actionable::action-target properties, the role of the button (i.e. whether it is a plain, check or radio button) is determined by the type of the action and doesn’t have to be explicitly specified with the property::ModelButton::role property.

The content of the button is specified by the property::ModelButton::text and property::ModelButton::icon properties.

The appearance of model buttons can be influenced with the property::ModelButton::centered and property::ModelButton::iconic properties.

Model buttons have built-in support for submenus in PopoverMenu. To make a GtkModelButton that opens a submenu when activated, set the property::ModelButton::menu-name property. To make a button that goes back to the parent menu, you should set the property::ModelButton::inverted property to place the submenu indicator at the opposite side.

Example

⚠️ The following code is in plain ⚠️

modelbutton
├── <child>
╰── check

⚠️ The following code is in plain ⚠️

modelbutton
├── <child>
╰── radio

⚠️ The following code is in plain ⚠️

modelbutton
├── <child>
╰── arrow

GtkModelButton has a main CSS node with name modelbutton, and a subnode, which will have the name check, radio or arrow, depending on the role of the button and whether it has a menu name set.

The subnode is positioned before or after the content nodes and gets the .left or .right style class, depending on where it is located.

⚠️ The following code is in plain ⚠️

button.model
├── <child>
╰── check

Iconic model buttons (see property::ModelButton::iconic) change the name of their main node to button and add a .model style class to it. The indicator subnode is invisible in this case.

A gio::Icon that will be used if iconic appearance for the button is desired.

If this property is set, the button will show an icon if one is set. If no icon is set, the text will be used. This is typically used for horizontal sections of linked buttons.

The name of a submenu to open when the button is activated. If this is set, the button should not have an action associated with it.

The name of a submenu to open when the button is activated. If this is set, the button should not have an action associated with it.

Specifies whether the button is a plain, check or radio button. When property::Actionable::action-name is set, the role will be determined from the action and does not have to be set explicitly.
