Different of the other books on Xlib that throw the routines expecting the reader to put them together and understand how them connect to each other (an approach not that different from learning just by reading man pages), this book explains the routines as it provides examples, in the same style of K&R's The C Programming Language (but less elegantly).
I am reading it RN.

I saw that one when I looked on Amazon in response to your query, but couldn't vouch for it myself. Let us know what you think after you've read it!
