set_titlebar

Description:

[ Version ( since = "3.10" ) ]
public void set_titlebar (Widget? titlebar)

Sets a custom titlebar for this.

A typical widget used here is HeaderBar, as it provides various features expected of a titlebar while allowing the addition of child widgets to it.

If you set a custom titlebar, GTK+ will do its best to convince the window manager not to put its own titlebar on the window. Depending on the system, this function may not work for a window that is already visible, so you set the titlebar before calling show.

Parameters:

this	a Window
titlebar	the widget to use as titlebar
