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.


Public Member Functions

const GtkScale* Gtk::Scale::gobj (  )  const [inline]
 

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::Range.

Reimplemented in Gtk::VScale, and Gtk::HScale.

virtual Glib::ustring Gtk::Scale::on_format_value ( double  value  )  [protected, virtual]
 

Glib::PropertyProxy<int> Gtk::Scale::property_digits (  ) 
 

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<bool> Gtk::Scale::property_draw_value (  ) 
 

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<PositionType> Gtk::Scale::property_value_pos (  ) 
 

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

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.

Glib::SignalProxy1<Glib::ustring,double> Gtk::Scale::signal_format_value (  ) 
 

Prototype:
Glib::ustring format_value(double value)
