16// //
17// TGTripleVSlider and TGTripleHSlider //
18// //
19// TripleSlider inherit from DoubleSlider widgets and allow easy //
20// selection of a min, max and pointer value out of a range. //
21// The pointer position can be constrained to edges of slider and / or //
22// can be relative to the slider position. //
23// //
24// To change the min value press the mouse near to the left / bottom //
25// edge of the slider. //
26// To change the max value press the mouse near to the right / top //
27// edge of the slider. //
28// To change both values simultaneously press the mouse near to the //
29// center of the slider. //
30// To change pointer value press the mouse on the pointer and drag it //
31// to the desired position //
32// //
33// Dragging the slider will generate the event: //
34// kC_VSLIDER, kSL_POS, slider id, 0 (for vertical slider) //
35// kC_HSLIDER, kSL_POS, slider id, 0 (for horizontal slider) //
36// //
37// Pressing the mouse will generate the event: //
38// kC_VSLIDER, kSL_PRESS, slider id, 0 (for vertical slider) //
39// kC_HSLIDER, kSL_PRESS, slider id, 0 (for horizontal slider) //
40// //
41// Releasing the mouse will generate the event: //
42// kC_VSLIDER, kSL_RELEASE, slider id, 0 (for vertical slider) //
43// kC_HSLIDER, kSL_RELEASE, slider id, 0 (for horizontal slider) //
44// //
45// Moving the pointer will generate the event: //
46// kC_VSLIDER, kSL_POINTER, slider id, 0 (for vertical slider) //
47// kC_HSLIDER, kSL_POINTER, slider id, 0 (for horizontal slider) //
48// //
49// Use the functions GetMinPosition(), GetMaxPosition() and //
50// GetPosition() to retrieve the position of the slider. //
51// Use the function GetPointerPosition() to retrieve the position of //
52// the pointer //
