set_focus

Description:

public void set_focus (Widget? focus)

Sets the focus widget.

If focus is not the current focus widget, and is focusable, sets it as the focus widget for the window. If focus is null, unsets the focus widget for this window. To set the focus to a particular widget in the toplevel, it is usually more convenient to use [method@Gtk.Widget.grab_focus] instead of this function.

Parameters:

this	a window
focus	the new focus widget
