- INTRODUCTION
- SliderCDEF is a control definition function for a
- slider with a simple indicator and a track without
- arrows on the end and that also displays the slider's
- value centered above the indicator outside the
- control's rectangle. The slider uses offscreen
- graphics worlds and VBL tasks to give smooth animation
- of the thumb as it is dragged around the track.
- However, the slider is still incomplete: it only
- handles horizontal configurations, it doesn't have
- a disabled state, and it requires System 7.0 and color.
- Since many peoply have been asking for slider control
- on the net lately, I thought I'd release it without
- it being completely finished. In its present state is
- is clear and well documented and could be easily
- modified for more specific needs.
-
- The archive contains source code written with
- Think C 5.04 as well as a resource file containing
- the CDEF, and a small demonstration application. The
- archive is Stuffit 3.0 and has been binhexed.
-
- SliderCDEF is provided free of charge, however if
- you do use it in a piece of software or make
- significant improvements, I'd like to hear about it
- and see the results.

- FUTURE ENHANCEMENTS
- SliderCDEF should be enhanced to handle vertical
- sliders and to display a disabled state. It should
- probably use DeviceLoop to do its drawing so that
- it could be properly displayed across different
- monitors. Some portions could be better optimized
- in the quest to eliminate more flickering. Finally,
- other parts could be added to the the slider such
- as arrows on either end. This could be another
- variation of the slider.
