[Xcb] Searching for tutorials

[Patrick]

Hi Everyone

This is my first post here.

I am trying my very best to follow along with this tutorial:
http://www.x.org/releases/X11R7.6/doc/libxcb/tutorial/index.html

There is the reference manual and many tiny snippets of code on the 
internet. I am now understanding about 60-70% of what I need to 
understand, to use the library but I am still struggling with some topics.

It looks like XCB_EVENT_MAKE_EVENT_HANDLER might have something to do 
with assigning a callback function but I can't find enough resources to 
understand it. Could anyone point me to a tutorial or other resource 
that would help me figure out how to call foo when the foo button(or 
window really) is pressed ? Right now I can understand button events but 
not how to distinguish between them.

The tutorial above also discussed how important pixmaps are but I still 
can't figure out how to write one to a window to turn that window into 
an image button and so on. Any resources for this would be great too.

Thanks for reading my post
