## Class Description

     TGSlider, TGVSlider and TGHSlider

     Slider widgets allow easy selection of a range.
     Sliders can be either horizontal or vertical oriented and there is
     a choice of two different slider types and three different types
     of tick marks.

     TGSlider is an abstract base class. Use the concrete TGVSlider and
     TGHSlider.

     Dragging the slider will generate the event:
     kC_VSLIDER, kSL_POS, slider id, position  (for vertical slider)
     kC_HSLIDER, kSL_POS, slider id, position  (for horizontal slider)

     Pressing the mouse will generate the event:
     kC_VSLIDER, kSL_PRESS, slider id, 0  (for vertical slider)
     kC_HSLIDER, kSL_PRESS, slider id, 0  (for horizontal slider)

     Releasing the mouse will generate the event:
     kC_VSLIDER, kSL_RELEASE, slider id, 0  (for vertical slider)
     kC_HSLIDER, kSL_RELEASE, slider id, 0  (for horizontal slider)

TString GetTypeString() const

     Returns the slider type as a string - used in SavePrimitive().
