Description

Base class for horizontal or vertical rulers

Synopsis

Detail

The Ruler widget is a base class for horizontal and vertical rulers. Rulers are used to show the mouse pointer's location in a window. The ruler can either be horizontal or vertical on the window. Within the ruler a small triangle indicates the location of the mouse relative to the horizontal or vertical ruler. See HRuler to learn how to create a new horizontal ruler. See VRuler to learn how to create a new vertical ruler.

Rulers are removed in Gtk3 and thus this module is blank. There is no replacement
