I'm going to assume you are using fltk 1.1.x (cause that's what I use ;) )
To load the images, use Fl_Shared_Image. That way you can load not only png
files, but bmp, xpm, and jpg with no extra effort.
Then you want to create a Fl_Box with the label set as "" (empty string) and
a box type of FL_FLAT_BOX. Finally, use Fl_Box::image(Fl_Image *) to set
the image you want for the widget.
Here's an example,
Fl_Shared_Image *img = Fl_Shared_Image::get("/path/to/image.png");
Fl_Box *w = new Fl_Box(X, Y, img->w(), img->h(), "");
w->box(FL_FLAT_BOX);
w->align(FL_ALIGN_INSIDE | FL_ALIGN_LEFT);
If you use FLUID to design you app, then its even easier. Just set the image
field to the path of your image file. Then use in the _inside_ alignment
for the label.
Just one more note. In fltk 1.1.x, done this way, an image on the widget is
considered part of the widget's label.
