fl_draw() [1] is your friend. There's no way to do it with an image/label
combination. You need to derive your own widget and write a simple
draw() method, something like:
MyBox::draw() {
Fl_Box::draw(); // if Fl_Box is your parent class
// this will also draw the image()
// and maybe the label() text
fl_color(FL_RED);
fl_font(FL_HELVETICA,22);
fl_draw("this is red text\nwith a 22 px. font",x()+10,y()+20);
}
You can find more info in the introduction chapter about drawing [2], including
measurement of strings [3].
