Class Description

                                                                      
 TGTripleVSlider and TGTripleHSlider                                  
                                                                      
 TripleSlider inherit from DoubleSlider widgets and allow easy        
 selection of a min, max and pointer value out of a range.            
 The pointer position can be constrained to edges of slider and / or  
 can be relative to the slider position.                              
                                                                      
 To change the min value press the mouse near to the left / bottom    
 edge of the slider.                                                  
 To change the max value press the mouse near to the right / top      
 edge of the slider.                                                  
 To change both values simultaneously press the mouse near to the     
 center of the slider.                                                
 To change pointer value press the mouse on the pointer and drag it   
 to the desired position                                              
                                                                      
 Dragging the slider will generate the event:                         
 kC_VSLIDER, kSL_POS, slider id, 0  (for vertical slider)             
 kC_HSLIDER, kSL_POS, slider id, 0  (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)       
                                                                      
 Moving the pointer will generate the event:                          
 kC_VSLIDER, kSL_POINTER, slider id, 0  (for vertical slider)         
 kC_HSLIDER, kSL_POINTER, slider id, 0  (for horizontal slider)       
                                                                      
 Use the functions GetMinPosition(), GetMaxPosition() and             
 GetPosition() to retrieve the position of the slider.                
 Use the function GetPointerPosition() to retrieve the position of    
 the pointer
