102 The constructor creates the progress bar using the position, size, and label.
104 You can set the background color with color() and the
105 progress bar color with selection_color(), or you can set both colors
106 together with color(unsigned bg, unsigned sel).
108 The default colors are FL_BACKGROUND2_COLOR and FL_YELLOW, resp.

, L

112 align(FL_ALIGN_INSIDE
