The main reason it's failing is because you're trying to install an RPM 
intended for a Mandrake/Mandriva Linux system. I believe there are RPMs on 
the wxPython site which cover Fedora and other flavours of Linux - you should 
download one of those instead.

The PythonCard RPMs on my web site are also only for Mandrake/Mandriva Linux - 
you'll have similar problems if you try to install these on your machine.

I wrote to Brad off-list, and we got his problem fixed (he had an 
earlier version of PythonCard checked out from CVS, and it came earlier 
in his sys.path, so was being used in preference to his regular 
PythonCard install).

Sorry, we should have reported back to the list so that solution was 
available to others.

Brad,

i hope you have already solved this problem. I use PythonCard don Mac  
also. The key for me is to make sure that the correct wxPython is  
installed directly in my site-packages directory of the version of  
Python I am using and that PythonCard is installed in that same site- 
packages directory. Still, if that isn't enough, you might need to  
install a clean Python, wxPython, PythonCard setup. That always seems  
to work. Once your installation is working, PythonCard is flawless  
son the Mac.



By the way, I just did a brief PythonCard podcast, including using  
Kevin's PyCon 2005 talk on Python411 at www.awaretek.com/python/ 
index.html

I don't know, but you may need to get a wxPython suitable for Python 2.4 
since that's what you are using. Although the message *says*  ">= 2.3" 
it may be that when Python 2.4 came out, it imposed a stricter 
constraint.  I know the current (2.6.3) wxPython has different RPMs for 
Python 2.3 and 2.4

[Pythoncard-users] RPM Install Problem

[David W. <D.L...@ee...>]

I am trying to install Pythoncard on a newly installed Fedora Core 5
machine.
I have downloaded 
   wxPython-common-gtk2-unicode.i586 0:2.5.4.1-mdk101_py2.3

and am trying to install it with 
   yum localinstall wxPython-common-gtk...

but it is failing it with 

Error: Missing Dependency: python-base >= 2.3 is needed by package
wxPython-common-g....

My python is Python 2.4.3 (#1, Jun 13 2006, 11:46:08), which is
obviously > 2.3.  What is going on?

Please.

[Pythoncard-users] sizer documentation

[<kc1...@ya...>]

Hi list,

Is there any documentation on the panel manager? 
Google search indicates that it's in the wxWindow
documentation.  Before I dig that up, I like to know
if there's a simpler way.

I see how it's used in the sample program but there is
no comment or anything.

Thanks,

The problem turned out to be that I had an older version of 
PythonCard that I had checked out via CVS in a different directory in 
one of the directories in sys.path.  That older version didn't have 
helpful.py.

Thanks for the help. The idea of looking at sys.path was what I

Or if you're looking to pick up an awesome asynchronous toolkit, you
could use Twisted (http://www.twistedmatrix.com) to do that very simply.
(Very simply, that is, after you've had sufficient Kool-Ade, if you
will.)

I'm using Twisted together with Pythoncard and it's an absolutely killer
combo. Somebody with more experience than I should do a writeup on it;
that combination is the answer to a lot of developers' needs.

Re: [Pythoncard-users] multithreading Pythoncard applications

[<kc1...@ya...>]

Bonk, bonk, bonk!!!

Arh, that feels better.

Reason why my quick sample didn't work is because I am
running it in single thread mode!

Change:

self.myThread=MyBackgroundWorker(self).run()

to:

self.myThread=MyBackgroundWorker(self).start()

and you'll see why multi-threaded programs are
superior to non-multithreaded programs.

[Pythoncard-users] multithreading Pythoncard applications

[<kc1...@ya...>]

Somebody asked me for a sample program on how to
multithread a Pythoncard application.

Multithreading in Python is pretty easy to code.  All
you have to do is to declare a class that's
subclassing from the threading.thread class and then
kick start it with a start method.  Like:

import threading

class Worker(threading.Thread):
   def __init__(self):
      threading.Thread.__init__(self)

   def run(self):
   ....actual code...

myWorker=Worker().start()

The actual work, of course, is synchronization.  The
Thread class provides counters, locks, and so forth to
help that.

I've put together a very simple mind multi-thread
example to show how to do things in Pythoncard.  The
code doesn't quite work yet (I did it real quick over
lunch time) in that the thread doesn't release the CPU
like I expect it to and so one thread would hog the
CPU and doesn't switch between threads).  But for
those that are not familiar with multi-threading
PythonCard, this can serve as a sample.  

If you get the code to work properly, it should allow
the user to click the Start menu option twice, and it
would run 2 processing threads, and when the user
click on Stop, both threads would stop.

[Pythoncard-users] Mac resourceEditor/layoutEditor won't launch

[Brad A. <bra...@ma...>]

I've gotten back into trying to get my PythonCard app to run on Mac, 
and find myself getting stuck on launching resourceEditor.py or 
layoutEditory.py.  The problem seems like it should be easy to solve; 
I must be missing something obvious.

I installed PythonCard .82 using "sudo python setup.py" install, 
where Python is the built-in Python 2.3.5 bundled with Mac OS 10.4.x 
(Tiger). I have wxPython 2.6.3 installed but PythonCard seems to 
ignore it and use the 2.5.3 bundled version of wx.

The problem seems to be with importing the module "helpful" within 
PythonCard. Here is the transcript:

-=-=-=-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-


oms-ballen:/Library/Python/2.3/site-packages/PythonCard/tools/resourceEditor 
ballen$ pythonw resourceEditor.py

     from modules import backgroundInfoDialog

   File "<stdin>", line 1, in ?
ImportError: No module named helpful

-=-=-=-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-


If I change directory to the "site-packages", I can import 
PythonCard.helpful. However, I still can't launch resourceEditor.py 
or layoutEditor.py


oms-ballen:/Library/Python/2.3/site-packages/PythonCard/tools/resourceEditor

I believe that's not enough.  To do this kind of
things, you need to get into multi-threaded
programming.  Start a worker thread to loop over the
processing task.  Inside the loop, do a check to see
if the GUI created any changes (like a mouse click)
and if it does, you know to stop.

The GUI code, of course, has to know that a worker
thread has been started, and take action to make sure
that the user doesn't start another one while the
first one is working (like disable a button or something).

So long as your processing loop is running, there is no opportunity for 
the wxPython events to be processed and passed to your menu code.

Easiest, simplest, way to handle this is to ensure that your processing 
loop has something like

for file in theListOfFiles:   
     if globalStop: break
     processOneFile()
     wx.SafeYield(self)

This checks a global variable (which you would set to true when the 
"stop" button (or menu) was clicked), then processes one file, then 
yields control (which allows wx to process any events). 

There are a number of examples that do this in the PythonCard sample - 
see for instance gravity.py (or findfiles for "yield" in the samples 
directory).

Try putting a wx.SafeYield() or wx.Yield() inside of your long running 
loop and see if that helps.

I had a similar problem. Alex Tweedy answered as follows:

Menu items are not components, so you can't enable / disable them this way.

You do this by
    self.menuBar.setEnabled('main_menuAdd_Info', True)

assuming 'menuCommandsAutoRefresh' is the name of the menu item.
You can also do getEnabled, or getChecked/setChecked, etc.

Also, I have found that you cannot (or I cannot) change the checked 
state from a script called from the item itself. I can change it outside 
of the item script.

[Pythoncard-users] Execute menu item while processing

[hwphillips <bu...@ya...>]

I have written a program which involves a long process of copying 
files/converting files. I would like for the user to be able to stop the 
process. I put a "stop" menu item, but the program doesn't respond. The 
window titlebar goes white and nothing happens till the 
copying/converting process is over. Any assistance would be appreciated.

[Pythoncard-users] Setting menuitem check mark

[<kc1...@ya...>]

Hi list,

I am having trouble making the menuitem check mark to
behave properly.

In my resource file, both the checkable and checkd
options for a particular menuitem has been set to 1. 
Upon startup, I want to change the check mark base on
some other settings and I have code in the
on_initialize method to do that.  However, no matter
what I do, the check mark still comes out checked.  

I am assuming that I am not doing this properly.   The
code I am using in the on_initialize method:

found=False
for me in self.menuBar.menus:
   if me.getLabel()=="MyMenuLabel":
      for item in me.items:
         if item.getLabel()=="MyMenuItem":
            item.checked = 0 (let say)
            found=True
            break
   if found:
      break

The above code *doesn't* work.  The check mark value
is affected but the display is not.

What's the proper way to do this?

Thanks,

Re: [Pythoncard-users] Resource Editor problem

[Brian D. <deb...@ho...>]

Hi there,

I list the steps to my problem...

- Create a new app
- Select a button
- Place the button where I want
- click outside the button to deselect it... WOW... it doesnt work!!! the 
button never gets unselected, i minimize all in my desktop with the show 
desktop button...

Hope this helps to find out my problem... It is strange that noone else has 
the same issues....

I'll try installing on a friends computer and see what happens

PD:

My dependecies are...

Python 2.4
wxPython 2.5
PythonCard 0.82
on a windows XP SP2 machine

Kevin,

Thanks. I'll try to do a good job on a PythonCard podcast.
