Class Description

                                                                      
 TGSlider, TGVSlider and TGHSlider                                    
                                                                      
 Slider widgets allow easy selection out 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)
