* SECTION:gtkwindow
|
||
* @title: GtkWindow
|
||
* @short_description: Toplevel which can contain other widgets
|
||
*
|
||
* A GtkWindow is a toplevel window which can contain other widgets.
|
||
* Windows normally have decorations that are under the control
|
||
* of the windowing system and allow the user to manipulate the window
|
||
* (resize it, move it, close it,...).
|
||
*
|
||
* # GtkWindow as GtkBuildable
|
||
*
|
||
* The GtkWindow implementation of the #GtkBuildable interface supports
|
||
* setting a child as the titlebar by specifying “titlebar” as the “type”
|
||
* attribute of a <child> element.
|
||
*
|
||
* # CSS nodes
|
||
*
|
||
* |[<!-- language="plain" -->
|
||
* window.background
|
||
* ├── <child>
|
||
* ╰── <titlebar child>.titlebar [.default-decoration]
|
||
* ]|
|
||
*
|
||
* GtkWindow has a main CSS node with name window and style class .background.
|
||
*
|
||
* Style classes that are typically used with the main CSS node are .csd (when
|
||
* client-side decorations are in use), .solid-csd (for client-side decorations
|
||
* without invisible borders), .ssd (used by mutter when rendering server-side
|
||
* decorations). GtkWindow also represents window states with the following
|
||
* style classes on the main node: .tiled, .maximized, .fullscreen. Specialized
|
||
* types of window often add their own discriminating style classes, such as
|
||
* .popup or .tooltip.
|
||
*
|
||
* Generally, some CSS properties don't make sense on the toplevel window node,
|
||
* such as margins or padding. When client-side decorations without invisible
|
||
* borders are in use (i.e. the .solid-csd style class is added to the
|
||
* main window node), the CSS border of the toplevel window is used for
|
||
* resize drags. In the .csd case, the shadow area outside of the window
|
||
* can be used to resize it.
|
||
*
|
||
* GtkWindow adds the .titlebar and .default-decoration style classes to the
|
||
* widget that is added as a titlebar child.
|
||
*
|
||
* # Accessibility
|
||
*
|
||
* GtkWindow uses the %GTK_ACCESSIBLE_ROLE_WINDOW role.
