Simple open source paint program

Question

I am trying to experiment with expanding paint-like program adding custom features to it. Can you suggest a simple open source paint-like program written in C and using GTK+ library which I could expand? It should compile in Linux but also in Windows (using MinGW). Thanks.

EDIT:

I found this and it looks like something I was looking for, but I want something more simple if it exists.

Answer 1

I never had this urge, but my 4 year old daughter loves TuxPaint. I believe it uses GTK+.

Answer 2

Here's a link to the Multimedia -> Graphics -> Editors section of the Sourceforge software browser, sorted in descending order of most active:

Just click on "Filters" and add a programming language filter for C and you should get a nice concise set of results for what you're looking for.

Answer 3

If you want something really simple, I think following the official scribble tutorial would be the best choice. Here is a link to the resulting code: you can find it in the GTK+ source tarball under examples/.
