| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: trackbar
Returns the value of the visible-range property of the argument. This
property determines a sub-range of a trackbar
control's range that is
displayed as a bar drawn along the widget.
The visible-range is only displayed when the select-range property of a trackbar has a true value. The value of the visible-range property must be a list of two numbers both within the range of the control.
visible-range is
a property of the trackbar
class.
This property is not supported by the simple GTK trackbar
widget, where it will have no effect.
