Description

Gnome::Gtk4::WindowControls shows window frame controls.

Typical window frame controls are minimize, maximize and close buttons, and the window icon.

Gnome::Gtk4::WindowControls only displays start or end side of the controls (see side), so it's intended to be always used in pair with another Gnome::Gtk4::WindowControls for the opposite side, for example:

CSS nodes

A Gnome::Gtk4::WindowControls' CSS node is called windowcontrols. It contains subnodes corresponding to each title button. Which of the title buttons exist and where they are placed exactly depends on the desktop environment and decoration-layout value.

When empty is True, it gets the .empty style class.

Accessibility

Gnome::Gtk4::WindowControls uses the GTK_ACCESSIBLE_ROLE_GROUP role.
