25 // TGSlider, TGVSlider and TGHSlider //
26 // //
27 // Slider widgets allow easy selection of a range. //
28 // Sliders can be either horizontal or vertical oriented and there is //
29 // a choice of two different slider types and three different types //
30 // of tick marks. //
31 // //
32 // TGSlider is an abstract base class. Use the concrete TGVSlider and //
33 // TGHSlider. //
34 // //
35 // Dragging the slider will generate the event: //
36 // kC_VSLIDER, kSL_POS, slider id, position (for vertical slider) //
37 // kC_HSLIDER, kSL_POS, slider id, position (for horizontal slider) //
38 // //
39 // Pressing the mouse will generate the event: //
40 // kC_VSLIDER, kSL_PRESS, slider id, 0 (for vertical slider) //
41 // kC_HSLIDER, kSL_PRESS, slider id, 0 (for horizontal slider) //
42 // //
43 // Releasing the mouse will generate the event: //
44 // kC_VSLIDER, kSL_RELEASE, slider id, 0 (for vertical slider) //
45 // kC_HSLIDER, kSL_RELEASE, slider id, 0 (for horizontal slider) //
