#96073 — Trying pmw with python3: Lots of crashes!

Hi!

I took a look at tkinter. It is pretty simple but it's very hard to
construct some relatively more complex widgets.

So I looked at pmw.
Because my system only have pmw for python2, I downloaded pmw2 from its
site and installed it manually using pysetup.py install.

Trying the examples ...:
Some run fine.
Some just segfault!
Others crash with the folloing message:
	"No such Pmw version 'on3-pmw-doc'. Using default version '2.0.0'"

Is there anybody using pmw who can explain possible reasons for this?

Should I use it for small apps that need:
	1 or more canvas scrollable windows?
	1 scrollable list with several (few) column editable fields?

Do I need to go to more complex system like wxwidgets or pyside (QT)?
I looked at the last one but, from the 1st steps, it seems too complex.

Thanks.

Before anyone can suggest toolkits to look at, what kind of GUI are you
trying to build?  What kind of "complex" widgets are you trying to
construct?  By their very nature "complex" widgets are going to be,
well, complex.   Do you need data-driven forms?

It's in the post.
Simple widgets except for one multicolumn scrollable and editable list
and, in another case, a few grouped scrollable canvas.

For a multicolumn editable list I suggest using tablelist. There are 
Python bindings around. Scrolling in Tk is generally done by grouping 
together scrollbars and widgets in a frame and connecting the scrollbars 
scrollcommands with xview/yview.

I have found tablelist (tklib) and a wrapper to python2.
May be I'll give it a try changing the wrapper to python3.
For now I am trying (learning) Laura's suggestion kivy.

Thanks.

Did you get it from PyPI?
https://pypi.python.org/pypi/Pmw/2.0.0  ?

Last I heard Andy Robinson of reportlab had made it work with Python3.0,
so you might ask him about bizarre crashes.

You might also want to look at kivy, which works on desktops as well as
on mobile devices.  Get the examples directory and run the demos to see
if what it can do looks like what you want.

I got it from sourceforge but I checked now and it has the same md5.

Yes. pmw 2 works with python3. I saw in setup.py the code to install for
python2 and python3 depending on the python interpreter used.
And it is correctly installed in my python3 system. Some examples work
perfectly.
I have sent an email to Andy.

I have just installed it and successfully was able to run the 1st.
example. It has the big advantage of being portable to android!!

Thank you Laura for your suggestions.

First run Tools/Script/2to3.py to convert 2.x code to 3.x code. See the 
docstring.
