25 // TGDoubleSlider, TGDoubleVSlider and TGDoubleHSlider //
26 // //
27 // DoubleSlider widgets allow easy selection of a min and a max value //
28 // out of a range. //
29 // DoubleSliders can be either horizontal or vertical oriented and //
30 // there is a choice of three different types of tick marks. //
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 // //
39 // TGDoubleSlider is an abstract base class. Use the concrete //
40 // TGDoubleVSlider and TGDoubleHSlider. //
41 // //
42 // Dragging the slider will generate the event: //
43 // kC_VSLIDER, kSL_POS, slider id, 0 (for vertical slider) //
44 // kC_HSLIDER, kSL_POS, slider id, 0 (for horizontal slider) //
45 // //
46 // Pressing the mouse will generate the event: //
47 // kC_VSLIDER, kSL_PRESS, slider id, 0 (for vertical slider) //
48 // kC_HSLIDER, kSL_PRESS, slider id, 0 (for horizontal slider) //
49 // //
50 // Releasing the mouse will generate the event: //
51 // kC_VSLIDER, kSL_RELEASE, slider id, 0 (for vertical slider) //
52 // kC_HSLIDER, kSL_RELEASE, slider id, 0 (for horizontal slider) //
53 // //
54 // Use the functions GetMinPosition(), GetMaxPosition() and //
55 // GetPosition() to retrieve the position of the slider. //
