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