public interface Toplevel : Surface
public interface Toplevel : Surface
A `GdkToplevel` is a freestanding toplevel surface.
The `GdkToplevel` interface provides useful APIs for interacting with the windowing system, such as controlling maximization and size of the surface, setting icons and transient parents for dialogs.
Namespace: Gdk
Package: gtk4

- public abstract FullscreenMode fullscreen_mode { get; set; }
The fullscreen mode of the surface.
- public abstract void* icon_list { get; set; }
A list of textures to use as icon.
- public abstract bool modal { get; set; }
Whether the surface is modal.
- public abstract bool shortcuts_inhibited { get; }

Begins an interactive resize operation.
- public void focus (uint32 timestamp)
Sets keyboard focus to
surface
. - public ToplevelState get_state ()

- public void inhibit_system_shortcuts (Event? event)
Requests that the this inhibit the system shortcuts.
- public bool lower ()
Asks to lower the this below other windows.
- public bool minimize ()
Asks to minimize the this.
- public void present (ToplevelLayout layout)
Present this after having processed the `GdkToplevelLayout` rules.
- public void restore_system_shortcuts ()
Restore default system keyboard shortcuts which were previously inhibited.
- public void set_decorated (bool decorated)
Sets the toplevel to be decorated.
- public void set_deletable (bool deletable)
Sets the toplevel to be deletable.
- public void set_icon_list (List<Texture> surfaces)
Sets a list of icons for the surface.
- public void set_modal (bool modal)
Sets the toplevel to be modal.
- public void set_startup_id (string startup_id)
Sets the startup notification ID.
- public void set_title (string title)
Sets the title of a toplevel surface.
- public void set_transient_for (Surface parent)
Sets a transient-for parent.
- public bool show_window_menu (Event event)
Asks the windowing system to show the window menu.
- public bool supports_edge_constraints ()
Returns whether the desktop environment supports tiled window states.
- public bool titlebar_gesture (TitlebarGesture gesture)
Signals:
- public signal void compute_size (ToplevelSize size)
Emitted when the size for the surface needs to be computed, when it is present.
