26// TGColorPalette, TGColorPick and TGColorDialog. //
27// //
28// The TGColorPalette is a widget showing an matrix of color cells. The //
29// colors can be set and selected. //
30// //
31// The TGColorPick is a widget which allows a color to be picked from //
32// HLS space. It consists of two elements: a color map window from //
33// where the user can select the hue and saturation level of a color, //
34// and a slider to select color's lightness. //
35// //
36// Selecting a color in these two widgets will generate the event: //
37// kC_COLORSEL, kCOL_CLICK, widget id, 0. //
38// and the signal: //
39// ColorSelected(Pixel_t color) //
40// //
41// The TGColorDialog presents a full featured color selection dialog. //
42// It uses 2 TGColorPalette's and the TGColorPick widgets. //
