setDecorationLayout
Sets the decoration layout for the title buttons.
This overrides the property@Gtk.Settings:gtk-decoration-layout setting.
The format of the string is button names, separated by commas. A colon separates the buttons that should appear on the left from those on the right. Recognized button names are minimize, maximize, close and icon (the window icon).
For example, “icon:minimize,maximize,close” specifies a icon on the left, and minimize, maximize and close buttons on the right.
If property@Gtk.WindowControls:side value is @GTK_PACK_START, @self will display the part before the colon, otherwise after that.
Parameters
layout
a decoration layout, or null to unset the layout
