Base class for horizontal or vertical rulers
This widget is considered too specialized/little-used for GTK+, and will in the future be moved to some other package. 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.
The GTKRuler 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
<gtk-hruler> to learn how to create a new horizontal ruler.
<gtk-vruler> to learn how to create a new vertical ruler.
This class defines the following slots:
- Lower limit of ruler
- Upper limit of ruler
- Position of mark on the ruler
- Maximum size of the ruler
- The metric used for the ruler
This calls the
<gtk-metric-type>to set the ruler to units defined. Available units are GTK_PIXELS, GTK_INCHES, or GTK_CENTIMETERS. The default unit of measurement is GTK_PIXELS.
