I want to learn how to implement a GUI

[Søren]

in c++. i dont mean something like QT or gtk where you are passing code to prebuilt widgets. I want to know how those sort of things are implemented. Like drawing the whole thing and building it up from a really low level. how would i go about this?

it's all libraries. find a library you want to use, lol like gtk, and find a tutorial. most things work with C++

Read the source code.

In GNU/Linux, that would lead you to X lib. The widget toolkits are implemented on top of that (plus some other stuff like threading, signal systems, etc.).

XLibs, or if you use TK you can try TCL

Xine-ui uses XLib directly therefore I recommend you look at the source.

In Qt you can create all your own widgets as you wish

As in GTK+, though it is a bit more difficult because GTK+ is C and C structs make inheritance a little harder. But, in PyGtk this is quite easy (and even recommended).

What about PyQt?
