[GNUe-dev] GNUe & wxPython

[Michael Klatt]

Hi Everyone,

I need to setup an accounting system and looking at GNUe as a 
possibility.  I've been a python programmer for several years and work a 
lot with MySQL.

In case it wasn't common knowledge, Forms & Designer definitely don't work 
with wxPython 2.5.1.5.  When launching the Designer with wxPython 2.5.1.5 I 
get the following exception (which  cripples the application):

DB000: Traceback (most recent call last):
DB000:   File "C:\Program 
Files\Python\Lib\site-packages\gnue\designer\base\docks\SplitDock.py", line 
269, in RecalcSizes
DB000:     size = self.GetSize()
DB000:   File "C:\PROGRA~1\Python\Lib\site-packages\wx\core.py", line 8376, 
in GetSize
DB000:     return _core.Sizer_GetSize(*args, **kwargs)
DB000: TypeError: Expected a pointer
DB000: Traceback (most recent call last):
DB000:   File "C:\Program 
Files\Python\Lib\site-packages\gnue\designer\base\docks\SplitDock.py", line 
269, in RecalcSizes
DB000:     size = self.GetSize()
DB000:   File "C:\PROGRA~1\Python\Lib\site-packages\wx\core.py", line 8376, 
in GetSize
DB000:     return _core.Sizer_GetSize(*args, **kwargs)
DB000: TypeError: Expected a pointer

I believe this error is in the wxPython library.   See this thread:

http://lists.wxwidgets.org/archive/wxPython-dev/msg00533.html

I haven't taken the time to figure out if the problem is still present in 
the latest wxPython source in CVS. I get this exact exception in Linux too 
(Fedora Core 2).

Even with wxPython 2.4.2.4u, I still get the following exception in Windows 
XP after launching gnue-designer (Windows XP, Python 2.3.3, wxPython 
2.4.2.4u, latest Subversion code as of 08/09/04) :

DB000: Traceback (most recent call last):
DB000:   File "C:\Program 
Files\Python\Lib\site-packages\gnue\designer\forms\LayoutEditor\LayoutEditor.py", 
line 146, in __OnGridSize
DB000:     w, h = self.panel.GetSizeTuple()
DB000: AttributeError: 'NoneType' object has no attribute 'GetSizeTuple'
DB000: Traceback (most recent call last):
DB000:   File "C:\Program 
Files\Python\Lib\site-packages\gnue\designer\forms\LayoutEditor\LayoutEditor.py", 
line 517, in OnPageSelected
DB000:     self.__OnGridSize(None)
DB000:   File "C:\Program 
Files\Python\Lib\site-packages\gnue\designer\forms\LayoutEditor\LayoutEditor.py", 
line 146, in __OnGridSize
DB000:     w, h = self.panel.GetSizeTuple()
DB000: AttributeError: 'NoneType' object has no attribute 'GetSizeTuple'

This error doesn't appear to affect the application.  This exception 
doesn't show up in wxPython 2.4.2.4 on Linux.

I updated the Windows Installation page in the Wiki to indicate that 
wxPython 2.5.1.5 won't work.

If there is somewhere else I should report bugs like this, please let me know.
