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 //
