There are times during debugging when it would be real useful to be able to
|
||
|
|
print the fields of an event in a human readable form. Too many times I found
|
||
|
|
myself scrounging around in section 8 of the Xlib manual looking for the valid
|
||
|
|
fields for the events I wanted to see, then adding printf's to display the
|
||
|
|
numeric values of the fields, and then scanning through X.h trying to decode
|
||
|
|
the cryptic detail and state fields. After playing with xev, I decided to
|
||
|
|
write a couple of standard functions that I could keep in a library and call
|
||
|
|
on whenever I needed a little debugging verbosity. The first function,
|
||
|
|
GetType(), is useful for returning the string representation of the type of
|
||
|
|
an event. The second function, ShowEvent(), is used to display all the fields
|
||
|
|
of an event in a readable format. The functions are not complicated, in fact,
|
||
|
|
they are mind-numbingly boring - but that's just the point nobody wants to
|
||
|
|
spend the time writing functions like this, they just want to have them when
|
||
|
|
they need them.
|
||
|
|
|
||
|
|
A simple, sample program is included which does little else but to demonstrate
|
||
|
|
the use of these two functions. These functions have saved me many an hour
|
||
|
|
during debugging and I hope you find some benefit to these. If you have any
|
||
|
|
comments, suggestions, improvements, or if you find any blithering errors you
|
||
|
|
