### Method

# Gtk Windowset_focus

#### Declaration [src]

    void
    gtk_window_set_focus (
      GtkWindow* window,
      GtkWidget* focus
    )

#### Description [src]

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 `gtk_widget_grab_focus()` instead of this function.

#### Parameters

`focus`

  Type: `GtkWidget`

  Widget to be the new focus widget, or `NULL` to unset any focus widget for the toplevel window.

  The argument can be `NULL`.
