25// TGTripleVSlider and TGTripleHSlider //
26// //
27// TripleSlider inherit from DoubleSlider widgets and allow easy //
28// selection of a min, max and pointer value out of a range. //
29// The pointer position can be constrained to edges of slider and / or //
30// can be relative to the slider position. //
31// //
32// To change the min value press the mouse near to the left / bottom //
33// edge of the slider. //
34// To change the max value press the mouse near to the right / top //
35// edge of the slider. //
36// To change both values simultaneously press the mouse near to the //
37// center of the slider. //
38// To change pointer value press the mouse on the pointer and drag it //
39// to the desired position //
40// //
41// Dragging the slider will generate the event: //
42// kC_VSLIDER, kSL_POS, slider id, 0 (for vertical slider) //
43// kC_HSLIDER, kSL_POS, slider id, 0 (for horizontal slider) //
44// //
45// Pressing the mouse will generate the event: //
46// kC_VSLIDER, kSL_PRESS, slider id, 0 (for vertical slider) //
47// kC_HSLIDER, kSL_PRESS, slider id, 0 (for horizontal slider) //
48// //
49// Releasing the mouse will generate the event: //
50// kC_VSLIDER, kSL_RELEASE, slider id, 0 (for vertical slider) //
51// kC_HSLIDER, kSL_RELEASE, slider id, 0 (for horizontal slider) //
52// //
53// Moving the pointer will generate the event: //
54// kC_VSLIDER, kSL_POINTER, slider id, 0 (for vertical slider) //
55// kC_HSLIDER, kSL_POINTER, slider id, 0 (for horizontal slider) //
56// //
57// Use the functions GetMinPosition(), GetMaxPosition() and //
58// GetPosition() to retrieve the position of the slider. //
59// Use the function GetPointerPosition() to retrieve the position of //
60// the pointer //
