Hello,

the ClassDesigner crashes again, this time no stack trace but a

segmentation fault. It happens when I try to change something in the

object inspector, no matter what or so it seems to me at the moment.

Clicking into a checkbox in the object inspector changes it to an edit

field with "False" or "True". This doesn't look right anyway. The crash

happens when I leave this field - but it happens also when I change

other, non boolean properties.

All this on Xubuntu 12.10:

Platform: GTK

Python Version: 2.7.3 on linux2

Dabo Version: 0.9.9

UI Version: 2.8.12.1 on wxGTK (gtk2)

Then I wanted to try on Debian stable and got a new error: Started the

class designer (this time not from its own directory but from the ui

directory of the application), tried to open an existing .cdxml file and

got:

sib@gespenst-debian:~/bin/urlaub/ui$ ~/src/dabo-trunk/ide/ClassDesigner.py

file.") % pth)

IOError: The file '/home/sib/bin/dabosib/testcd_2/ui/TestPanel_3.cdxml'

does not appear to be a valid class file.

The file mentioned in the traceback hasn't anything to do with the file

I wanted to open and it's in another directory.

Platform: GTK

Python Version: 2.6.6 on linux2

Dabo Version: 0.9.9

UI Version: 2.8.10.1 on wxGTK (gtk2)

Of course I could hand code all forms but it would be much more work,

because I want to change a working application with lots of panels made

with the class designer.

Thank you for help,

Sibylle

Would you mind doing a bit of regression testing? Loading up dabo 0.9.5 and seeing if

the error is still there, if not then 0.9.6, etc.? It would help to know when this

behavior went south.

Weird, I have the same setup as you and I don't get segfaults, although I do see the

"False" and "True" in the boolean grid editor like you do.

I'm sure I'm to blame for these problems, and I think they probably stem from work I

did trying to get dGrid working right on wx2.9.4/64 on Mac, about 2 months ago. It

turns out it is pretty hard to avoid segfaults when working with grid editors, and I

altered a segfault workaround I'd put in place over 5 years ago. I probably just need

to revert all that and forget about the future wxPython versions for now.

Anyway, if you could confirm which dabo version introduced the problem, that would

still help.

Thanks

Paul

How do I get the old versions? Preferably without having to learn too

much about git ...

I've looked at https://github.com/dabodev/dabo, but I don't see how to

get the right files.

Thank you,

Sibylle

Go to https://github.com/dabodev/dabo/tags and then for each version you want to

download click the '.zip' or '.tar.gz' link. Save, extract, put it in your pythonpath

or 'python setup.py install'.

Thanks

Paul

Another easy way with git is to just run "git checkout v0.9.5", and that will change your code to that version. When you are done, just run "git checkout master" to go back to the current version.

Did that. No problems with version 0.9.5, after removing the reference

to GridHeaderPaint from ClassDesignerControlMixin.py. New problem with

version 0.9.6: opening a saved class gives this:

sib@gespenst-xubuntu:~/src/dabo-trunk$ ide/ClassDesigner.py

Traceback (most recent call last):

File "ide/ClassDesigner.py", line 4474, in <module>

clsDes = ClassDesigner(f)

File "ide/ClassDesigner.py", line 311, in __init__

self.start()

File "/home/sib/src/dabo-trunk/dabo/dApp.py", line 391, in start

self._retrieveMRUs()

File "/home/sib/src/dabo-trunk/dabo/dApp.py", line 485, in _retrieveMRUs

cleanCap = cleanMenuCaption(cap)

NameError: global name 'cleanMenuCaption' is not defined

Version 0.9.7: opening the saved class works again, but now the

segmentation fault appears when I try to change a property.

Greetings

Sibylle
