Gtk::Scale*  wrap (GtkScale* object, bool take_copy=false) Detailed Description Abstract base clase for Gtk::HScale and Gtk::VScale. A Gtk::Scale is a slider control used to select a numeric value. To use it, you'll probably want to investigate the methods on its base class, Gtk::Range, in addition to the methods for Gtk::Scale itself. To set the value of a scale, you would normally use set_value(). To detect changes to the value, you would normally use signal_value_changed(). The Gtk::Scale widget is an abstract class, used only for deriving the subclasses Gtk::HScale and Gtk::VScale, so you should instantiate them instead.

Glib::PropertyProxy<bool> Gtk::Scale::property_draw_value (   )    Whether to draw the value as a string next to slider. Glib::PropertyProxy<PositionType> Gtk::Scale::property_value_pos (   )    The position in which the value is displayed. void Gtk::Scale::set_digits ( int    digits )    Set the number of decimal digits. This also causes the adjustment to be rounded off so the retrieved value matches the value the user sees. Setting digits to 1 gives for example 1.0, 2 gives 1.00, etc. void Gtk::Scale::set_draw_value ( bool    draw_value = true )    Set whether the current value is displayed as a string next to the slider. void Gtk::Scale::set_value_pos ( PositionType    pos )    Set the position in which the value is displayed.
