Please read my question!
I need to put an icon in a Window, and I need this icon to be written inside the source!

Example: my_icon = image data

I don't want the icon to be pulled from Hard Disk. And not from the internet or any place you can imagine!
my_icon = icon.png

Can anyone tell me how I can do this?
At the moment I use fltk to create the window, but I can't find it and I don't know how to assign the written icon data inside the source.
