Simple X11 toolkit

This toolkit is created as a way to learn X11 programming. It is completely written in C++ and has support for:

• Images: XPM, the default X images and jpg, png, gif, etc. through imlib2
• Buttons, labels, customizable background color
• C style function callbacks providing customizable events
• Anti-aliased fonts
• Basic label wrapping and image scaling
• Adding new widgets and subwidgets inside other widgets by using the Widget class
• Poor man double buffering and X11 expose redraws

It is not complete and far from bugfree. It is public domain, you can print it out and even sell it to trolltech.com for a million dollars so they can use it in Qt ;), I don't care (although I would be interested if you actually use something from this project, mail me if you do).

I learned that programming in X11 can be tedious. It provides an object oriented approach but it uses C, not C++. So you probably want to wrap things inside C++ classes to make life easier. Things get complicated since some function calls reserve memory and need to be free-ed, but this differs per function. Therefore, the use of a good memory management tool, such as Valgrind is advisable. Anyway, try it and leave it. And remember, X11 internals are like reading code from 1980. You are warned...
