set_title

Sets the title of a toplevel window, to be displayed in the titlebar.

If you haven’t explicitly set the icon name for the window (using set_icon_name ), the icon name will be set to title as well. title must be in UTF-8 encoding (as with all user-readable strings in GDK/GTK+). title may not be null.

Parameters:

this	a toplevel Window
title	title of this
