Python 2.7 GUI Support

[MichaMans]

I figuered out, that the GUI wont start under Python 2.7
The controller cannot be imported.
I think we can handle this by adding the init.py to the Controller.
Propably there are some more problems we have to fix that are Python 2.7 related (Some other GUI things). Or we don't support it anymore.

[PRemmen]

We should/need to support that, also in the GUI.
@yGoerguelue and @CGingter could you fix that? Is it possible to implement UnitTests also for GUI

[CGingter]

There is no reason why the controller should not have a init.py but teaser behaves really weird in Python 2.7. This looks like a lot of research/work so i would propose to give it to @yGoerguelue because i got only one week left.

[PRemmen]

Please specify what you mean by "behaves really weird"? Because all functions that are implemented in the unit tests (almost all containend in Logic) run in python 2.7 and python 3.4!

[CGingter]

Ok so for example the load building function lets you only select .xml files which is nowhere specified. When you load a building the paint function gets called infinite times and the program gets shut down. That was the only thing i tested so far but it is really strange.

[CGingter]

Oh wait he just starts an older version...which is still weird...let me look into it!

I don't understand this. what "paint" function do you mean? And how can I select a .xml file that is nowhere defined? Maybe like a hardcoded path somewhere?
Update:
Ahh understand the .XML problem now, still not thinkng that this is a python 2.7 / 3.4 problem

[CGingter]

That's not what i meant. For some reason if i select the python 2.7 interpreter it uses an old teaser 4 version. In this version you could only select .xml files in the file dialog when you clicked on Load Building and also some newer buttons are missing. The paint function is a PYQT function that draws all the controls and it breaks when trying to fill in the zone lists, but this is of no concern since it is most likely just a bug in this old version.

So the question is why does it load an old version and not the current one?

[PRemmen]

Maybe you need to update you installation of teaser with pip for 2.7

[CGingter]

Got it figured out...well actually i just deleted my workspace and made a new one but hey whatever works...

Still getting some errors, can hopefully solve it today!

[yGoerguelue]

@MichaMans I can start the GUI ordinary under Python 2.7. Maybe you don't have the package(PyQt4) that is needed. Look if you can find the folder PyQt4 in "C:\Python27\Lib\site-packages".

[yGoerguelue]

@PRemmen Strange things are happening, if i start the GUI in branch (issue57...) with python27 and load a Project into it. Everything works, but if I do a double click on the zone element and nothing happens. If I start the GUI in another branch like issue47 or issue41 everything works fine.

[MichaMans]

So i looked into the development branch. its not starting with python 2.7. I think a coding decleration would help here (since i get and ASCII error in a commented block). like first line

# -*- coding: utf-8 -*-

But i'm not sure if this will help or if this is a right solution.

[yGoerguelue]

That's the problem with the German language, we can't use german characters like ß,ö,ä, ü. For now we shouldn't use german characters. I will fix it tomorrow and search for an alternative solution.

[CGingter]

To circumvent the ASCII error you can use the html escaped string instead of the character. You can search in the MainUI class for & # 1 7 6; which is °. ß for example would be & # 2 2 3;. Good luck!

Just write it together and ignore the spaces between & and ; because else this website converts it to the symbol. Whoops!
