Sliders

No, this isn't to do with the American Sci-Fi program – sliders are a horizontal bar that the user can can to specify a value.

Sliders can be created with :

DDgui_slider(id$, value [,width%, height%])

with id$ being a unique identifier, and value is the default value to be used.

width% and height% are optional.  If these are given, the the widget will be created with the horizontal size defined by width% and the vertical size by height%.

By default, the slider range is between 0.0 and 1.0, with a step value of 0.01

The minimum range can be changed using DDgui_set and a MINVAL parameter, whilst the maximum value can be changed using DDgui_set and a MAXVAL parameter

Note :

• You need to make sure that the pointer position is always between the minimum and maximum range
