###   qtpqrqpin   ###


to build run 

qmake && make

in qtpqrapin directory: 


qpqrapin is a little GUI to demonstrate 
how to use the parapin stuff with QT4.

It expect the kernerl-modul-diver as 
"/dev/ppdrv_device"
as suggested in the parapin examples.

You can easily change this device name in 
line 32 of the qtparapinwidgets.cpp to fit 
your needs.

"readme.png" is a screenshot of the GUI.

This stuff made with OpenSuse 10.2, 
qt4.2.1, designer 4.3
 
I made the qtparapin because i tried to 
implement the parapin functionality to 
the "KSIMUS" electronic simulator made 
by Rasmus Diekenbrock.
And this works already for output.

I had some trouble with closing the device 
in qt4 environment and figured out that it
work properly when using "::" operator for 
open and close operation.
See line 32 and 69 of qtparapinwidgets.cpp 

Also i met some confusion on the "2 natures"
of parapin. 
Kernel-modul-driver, Userspace driver etc.
On some mailinglists and fotums this expressions 
are used in different meanings.

For sure its possible to make this all more 
elegant but it should be only a beginners example.
