If your application needs this widget, feel free to use it, as the widget does work and is useful in some applications; it's just not of general interest. However, we are not accepting new features for the widget, and it will eventually move out of the GTK+ distribution.</p></div><p>The HRuler widget is a widget arranged horizontally creating a ruler that isutilized around other widgets such as a text widget. The ruler is used to showthe location of the mouse on the window and to show the size of the window inspecified units.
