Gtk::Ruler*  wrap (GtkRuler* object, bool take_copy=false) Detailed Description Base class for horizontal or vertical rulers. NOTE 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. Rulers are used to show the mouse pointer's location in a window. The ruler can either be horizontal or vertical. Within the ruler a small triangle indicates the location of the mouse relative to the horixontal or vertical ruler. This is an abstract base for Gtk::HRuler and Gtk::VRuler. Users should only instantiate those types. Constructor & Destructor Documentation virtual Gtk::Ruler::~Ruler (   )  [virtual] Gtk::Ruler::Ruler (   )  [protected] Member Function Documentation void Gtk::Ruler::draw_pos (   )    draw a position indicator on the ruler virtual void Gtk::Ruler::draw_pos_vfunc (   )  [protected, virtual] void Gtk::Ruler::draw_ticks (   )    draw tick marks on the ruler virtual void Gtk::Ruler::draw_ticks_vfunc (   )  [protected, virtual] MetricType Gtk::Ruler::get_metric (   )    Gets the units used for a Gtk::Ruler. See set_metric(). Returns: The units currently used for ruler . MetricType Gtk::Ruler::get_metric (   )  const void Gtk::Ruler::get_range ( double&    lower, double&    upper, double&    position, double&    max_size )    Retrieves values indicating the range and current position of a Gtk::Ruler. See set_range(). Parameters: lower  Location to store lower limit of the ruler, or 0. upper  Location to store upper limit of the ruler, or 0. position  Location to store the current position of the mark on the ruler, or 0. max_size  Location to store the maximum size of the ruler used when calculating the space to leave for the text, or 0. double Gtk::Ruler::get_range_lower (   )  const double Gtk::Ruler::get_range_upper (   )  const const GtkRuler* Gtk::Ruler::gobj (   )  const [inline]   Reimplemented from Gtk::Widget.

The possible choices are: Gtk::PIXELS Gtk::INCHES Gtk::CENTIMETERS The default metric is Gtk::PIXELS. void Gtk::Ruler::set_range ( double    lower, double    upper, double    position, double    max_size )    sets the range of the ruler. upper and lower arguments denote the extents of the Ruler. max_size is the largest number displayed by the ruler. position gives the initial value of the ruler. Rulers do not have sane defaults so this function should always be called.
