Outside labels + are not considered. If you need outside labels of any widgets or free + space outside of this bounding box you can add a tiny invisible Fl_Box + at the relevant corner(s) of the Fl_Scroll widget, for instance: + \code + Fl_Scroll scroll(100, 100, 200, 200); // Fl_Scroll at (100, 100) + Fl_Box(100, 100, 1, 1); // Fl_Box in top left corner + Fl_Input(150, 120, 60, 30, "Input:"); // left most widget with label + // ... more widgets ... + scroll.end(); + \endcode + By default you can scroll in both directions, and the scrollbars disappear if the data will fit in the area of the scroll. |
