gtk:window-hide-titlebar-when-maximized (object)

object -- a gtk:window widget
setting -- a boolean whether to hide the titlebar when the window is maximized

The accessor for the hide-titlebar-when-maximized slot gets or sets whether the window has requested to have its titlebar hidden when maximized. If the setting argument is true, then the window will request that its titlebar should be hidden when maximized. This is useful for windows that do not convey any information other than the application name in the titlebar, to put the available screen space to better use. If the underlying window system does not support the request, the setting will not have any effect.
