// 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) //
