If you are running fltk-1.3, then this is pretty easy: See below.
The only trick to this is ensuring that the image is where you think it
is...
I have code to "help" with that too, though, if you need it.
---------
#include <FL/Fl.H>
#include <FL/Fl_PNG_Image.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_Button.H>
static Fl_Window *win = 0;
static Fl_Button *but = 0;
static Fl_PNG_Image *picture = 0;
void ButtonCallback(Fl_Widget *, void *) {
static int ncol = 53;
but->labelcolor((Fl_Color)ncol);
but->redraw();
/* get a different colour */
ncol += 5;
if(ncol > 80) ncol = 53;
}
int main(int argc, char **argv) {
picture = new Fl_PNG_Image("some-image-512x512.png");
win = new Fl_Double_Window(700, 600);
win->begin();
but = new Fl_Button(10, 10, 512, 512, "Push Me");
but->image(picture);
but->align(FL_ALIGN_IMAGE_BACKDROP);
but->labelcolor(FL_WHITE);
but->labelsize(28);
but->callback(ButtonCallback);
win->end();
win->show(argc, argv);
return Fl::run();
}
