Hi,
I am working on my first QGIS plug-in wohoo .
But honestly this is my first ever stab at OO code in python using
pyQT. I have <http://pastebin.com/dWT5eezP> http://pastebin.com/dWT5eezP (for
code highlighting - or see end of message below trace back)
The line
self.inputConfig()
throws his error : argument 1 has unexpected type 'instance' .See traceback
below. There I am trying to open a file selection dialogue window ....
Ay idea what it excepts instead of self ? Any python gurus ?
Thanks
Karsten
