Hello, I use a drawing area with 2 colors red and blue. But I don't know to get other colors . For these two I use the following defintion that were given me. blue.red = 0; blue.green = 0; blue.blue = 0xff * 0x100; gdk_colormap_alloc_color(colormap, &blue, FALSE, TRUE); red.red = 0xff * 0x100; red.green = 0; red.blue = 0; Could someone explain how to get other colors (for example white) ? Thanks. Valery Avaux
