Hello everybody!
My name is Jens Petersen and I am a student in mechanical engineering in
Flensburg (in the very north of germany!)
So at first: Sorry for my english, I hope you will understand!
At the moment, I am writing my diploma-thesis and a part of it is to be
programmed in python!
But there are some problems if you dont know anybody who knows python very
well, so I hope you can help me!
I have two problems at the moment!
1.: I cant insert my fields into the sizers!
2.: I need to give some values to a method, but I dont know how!
Further, there are some things which could be nicer, e.g. my tables dont
look very good because there are always these Scroll-Controls. Is it
possible to fit the table without these controls.
And the whole layout doesnt look good, too.
If youd like to help me, please explain or show me, how to use anchors
etc..
Please look at the code, my doc-strings explain my problems!
