Re: [Pythoncard-users] PythonCard on OS X 10.4

[<bra...@om...>]

I can't speak with any authority on this, but I don't think that 
PythonCard .81/.82 has been tested against Python 2.4.x. I ran into lots 
of problems with this and no one on the PythonCard list was able to help 
me with it, so I ended up continuing to use Python 2.3.5 for PythonCard 
.81 and .82. 

I was able to run PythonCard apps under 2.4.1, but got lots of exceptions 
and tracebacks in the terminal output, and as I recall Resource Editor was 
almost unuseable under Python 2.4.1. Of course, PythonCard is open source, 
so anybody with time to debug under Python 2.4.1 could do so to get to the 
bottom of the problem...

My PythonCard app seems to work ok under Mac OS 10.4.1 and Python 2.3.5, 
along  with wxPython 2.3.5 ansi (not Unicode). I doubt if 10.4 is the 
problem here.

I use PythonCard, I don't use (and never have used) Wax.  That's both a 
warning about how biased my answer is likely to be, and a large part of 
my answer :-)

I did look at them both, before choosing to investigate Pythoncard - and 
was sufficiently happy with what I found that I didn't need to go back 
to look in detail at Wax.

Wax *feels* to me like wxPython, only easier and better. You do 
everything in the code; you create and lay out your components by 
writing lines in your source code. Wax makes it better - feels Pythonic 
instead of feeling like C++ - but it's still very "remote" from the GUI 
appearance.  I prefer the feel of Pythoncard, where you can create and 
layout components in the resourceEditor (though if you need to, you can 
later move them, change them or create more of them in code).

Pythoncard makes it easy to use wxPython directly, for any controls or 
events which are not yet included in Pythoncard; it's not clear whether 
Wax allows the same.

Pythoncard is relatively active - not sure about Wax. I know Hans Nowak 
has said that he has little or no time to work on it, and is encouraging 
others to step forward if they wish to contribute; but as yet there are 
no additional developers listed on Sourceforge.

0.8.2 hasn't been released yet. You can download the current CVS
version, but this is not recommended for production use, and is really
only of use to those who want to help with testing new features and/or
bugfixes.

The instructions for obtaining the current Pythoncard source tree by
anonymous CVS can be found here:

Thanks for the heads-up, Bryan. I'm maintainer of the Pythoncard RPMs
for Mandrake/Mandriva, so I'll see if I can produce an updated version
which correctly detects the version of Python being installed. Failing
that, I'll put up an RPM specific to Python 2.4.

[Pythoncard-users] mandriva rpm installation

[Bryan M. <bmu...@gm...>]

Hi,

I've just installed PythonCard on my Mandriva Limited Edition 2005 box
using the mdk rpms.  There was a bit of a problem so I joined the
mailing list, but then found the solution and figured I'd share it.

Mandriva comes with python 2.4 and the rpm puts the PythonCard files
in /usr/lib/python2.3/site-packages.  You can still use the rpm, just
type as root:

/usr/lib/python2.4/site-packages
ln -s /usr/lib/python2.3/site-packages/PythonCard .

and then everything seems to work OK.

I figured out why I have 0.81 and thinking that it's
the latest version.  If you go to www.pythoncard.org

I was unable to figure out from a google search where
to download 0.82.

It does (at least, the version I have does). It has

    def on_fldURL_keyPress(self, event):
        keyCode = event.keyCode
        target = event.target
        if keyCode == 13:
            self.on_goURL_command(None)
        else:
            event.skip()
which is why I mentioned typing a URL to it. Check if your 
sample/simpleBroswer has that too ....

Sounds right - it previously had "TextArea1" in it (from the resource 
definition), so when you hit BACKSPACE it should:
print the "point" to the console window
and then execute the keyPress handler, which says
   def on_TextField1_keyPress(self, event):
       print event.keyCode
       self.components.TextArea1.text = self.components.TextArea1.text + 
"%d\n" % (event.keyCode)

i.e. add the decimal value of the keyCode to the end of the text of 
TextArea1; BACKSPACE is ctrl-H == 8, so this is what I'd expect.  Note I 
didn't do an event.Skip() in on_TextField1_keyPress, so the key would 
not be passed through the usual processing.....

so (tentatively) I think the modified code is giving the right result.

I can't see what's different between that and what I quoted in the 
original mail
Could you change lines 335-341 of PythonCard/event.py  from

class KeyEvent(Event):
    def decorate(self, aWxEvent, source):
        aWxEvent = Event.decorate(self, aWxEvent, source)
                # this is basically the same block as MouseEvent.decorate
        # but it seems wrong to have KeyEvent be a subclass of MouseEvent
        aWxEvent.position = tuple(aWxEvent.GetPosition()) 
(I only listed lines 335 to 341 - so apart from funny indentation of the 
comment, it looks the same as what you have).

Perhaps just the confusion of line-wrapping in email ?

As I said above - it looks as though it's working  for you 0.8.1, so 
unless you run into a problem, you may be able to stick with 0.8.1

(0.8.2 may be only in CVS)

We should make sure we get that fix incorporated - but maybe we'll let 
it sit until you have another week or two's experience, in case you run 
into anything else ....

RE: [Pythoncard-users] TextField bug?

[<kim...@ya...>]

Puzzle partially solved.

The issue is that there is an genuine problem of:

IndexError: tuple index out of range

as documented before.  However, python.exe doesn't
appear to be bothered by it.  Since I am doing my
development under WingIDE, I am seeing the error.

The next question is to what to do about the error.  I
will hunt down 0.82 and see if it does better.  As
indicated, my event.py looks different from yours.

the KeyEvent change again....standby

RE: [Pythoncard-users] TextField bug?

[<kim...@ya...>]

Okay, Alex,

The simpleBrowser example works.  May be it doesn't
use KeyEvent?

I replaced the KeyEvent code in pythoncard\event.py to
the code you listed and the program doesn't crash. 
It's not working like one would expect, however (may
be that's your purpose?)  When I hit a key, say
BACKSPACE,  the lower text field becomes
"TextArea18"...

Incidentally, my KeyEvent doesn't look like the one
you listed.  It's doing:

##
    def decorate(self, aWxEvent, source):
        aWxEvent = Event.decorate(self, aWxEvent,
source)
        
        # this is basically the same block as
MouseEvent.decorate
        # but it seems wrong to have KeyEvent be a
subclass of MouseEvent
        aWxEvent.position =
tuple(aWxEvent.GetPosition())
        aWxEvent.x = aWxEvent.GetX()
        aWxEvent.y = aWxEvent.GetY()
        aWxEvent.altDown = aWxEvent.AltDown()
        aWxEvent.controlDown = aWxEvent.ControlDown()
        aWxEvent.shiftDown = aWxEvent.ShiftDown()
        
        aWxEvent.keyCode = aWxEvent.GetKeyCode()
        return aWxEvent
##


From the Help function of the resource editor, I get:

PythonCard
        
PythonCard is a GUI construction kit for building
cross-platform desktop applications on Windows, Mac OS
X, and Linux, using the Python language.

PythonCard version: 0.8.1
wxPython version: 2.5.4.1
Python version: 2.3.5 (#62, Feb  8 2005, 16:23:02)
[MSC v.1200 32 bit (Intel)]
Platform: win32

I will look around and see if I can find 0.8.2.

Regarding the unicode version, so far the only problem
I found is in the multi-column control.  It was using
"String" as a class type check.  The proper check
should have been "Strings".


Thanks,

I'm running Python 2.4, wxPython 2.5.3, PCard 0.81 and despite best 
efforts I can't get either keyPress handler to crash. My suggestion, 
since it requires the least amount of work, would be to try downgrading 
to wx-2.5.3.x and see what happens. At least rule it out.

That doesn't happen for me; this little sample below opens its main 
window, then a child window overlapping it; when you click on the button 
within the child, the child window stays above the main window with the 
dialog above the child. After the dialog is closed, the child remains on 
top and has focus.

This might give you somewhere to start comparisons - or if you like, 
send the code that is misbehaving to me and I'll try to determine where 
the difference is.

[Pythoncard-users] PythonCard on OS X 10.4

[Arthur E. <ar...@ia...>]

Hi,

trying to install PythonCard on OS X 10.4, but running into an import  
problem.

I installed python2.4.1, wxPython2.6, TigerPython24Fix and  
TigerPython23Compat from Bob's packages page and added /usr/local/bin

pythoncard.. anyone know what can be wrong?

Well, I'm pretty baffled - so I really hope someone else can chime in 
with an idea.
In the meantime, I'll bash on, hoping I don't ask too many stupid 
questions or make too many stupid suggestions.


Earlier, you said:

Could you verify that the simpleBrowser sample works properly, including 
typing a URL into the URL field at the top ?

Looking at the code involved in the traceback, I would think tuple 
should be safe enough - so let's see what it's being called on.
Could you change lines 335-341 of PythonCard/event.py  from

> class KeyEvent(Event):
>     def decorate(self, aWxEvent, source):
>         aWxEvent = Event.decorate(self, aWxEvent, source)
>         
>         # this is basically the same block as MouseEvent.decorate
>         # but it seems wrong to have KeyEvent be a subclass of MouseEvent
>         aWxEvent.position = tuple(aWxEvent.GetPosition())

to

class KeyEvent(Event):
    def decorate(self, aWxEvent, source):
        aWxEvent = Event.decorate(self, aWxEvent, source)
       
        # this is basically the same block as MouseEvent.decorate
        # but it seems wrong to have KeyEvent be a subclass of MouseEvent
        mypoint = aWxEvent.GetPosition()
        print mypoint
        aWxEvent.position = tuple(mypoint)

and see if that tells us anything.
 If it fails one the  aWxEvent.GetPosition()   then let's print out the 
aWxEvent and see what's in it.

btw - you said you were using latest download of PythonCard, 0.81  but  
latest should be 0.82 (I think).
Could you possibly run the codeEditor (or resourceEditor) and click on 
Help/About PythonCard.... and check what it says; my system has

PythonCard version: 0.8.2
wxPython version: 2.5.3.1
Python version: 2.3.4 (#53, May 25 2004, 21:17:02) [MSC v.1200 32 bit 
(Intel)]
Platform: win32

which doesn't make it clear, but it's actually wxPython 
wx-2.5.3-msw-ansi where you have a unicode version.
(shouldn't matter - but it's the biggest difference I've seen in our 
version so far)

[Pythoncard-users] Question about child-window, dialog z-order

[<kim...@ya...>]

Hello list,

I am writing an app involving child-window.  When the
child window invokes a dialogbox, it switches focus to
the main windows first, before poping up. Of course,
when it closes, the child-window becomes underneath
the main window.

Is there a parameter I am suppose to set or something
in order to maintain the proper z-order?

Thanks,

Alex,

Your code crashed the same way on my system.  As soon
as I hit a key at the entry field, the program
crashed.

Re: [Pythoncard-users] TextField bug?

[John H. <kim...@ya...>]

No, the processing code has nothing with the problem. 
The point is that the mere existence of the keyPress
handling is causing the crash.  May be my handler is
not correct.  I looked at the sample Pythoncard sample
programs and didn't find any sample code on how to add
the keyPress event.

Thanks again.

Sounds like that's the culprit; dig in with your usual
debugging 
techniques to see where it is.
If you want more help - just holler. Liam's request
for the whole 
traceback is also a good idea if you want to send that
- but I think you 
now have it narrowed down to something in the "...some

[Pythoncard-users] PythonCard comparison

[Nicolas P. <nic...@la...>]

Hello,

I have a new project writting a software with python a language. My 
machine is running WinXP. As I have not much time to spend on it (It's a 
project I'm writting at home) I'm looking for a simple and efficient 
GUI. I have discovered PythonCard. It looks very interesting. I'm also 
interrested in WAX. Does anybody know this package ? How do you compare 
it with WAX ?

Regards,
Nicolas

There's a few ways that it could be handled....

One method that I have started to use with a Text Parsing engine is a
registry system....

The registry format that I use is along these lines....

Take a dictionary....

	1) The functions that are called are the keywords...
	2) The data portion of the dictionary is the function "pointer"


simple demo...

def	test ():
	print test
	return "registry demo..."

registry_data =3D {}
registry_data [ "test".upper().strip() ] =3D test
data_returned =3D registry_data ["TEST"]()

The drawback of this simplistic model, is that you can't easily exchange
data unless the registry is part of a larger class...  (Which my model
is...)

I have thought about extending it to support overloaded variables,
etc...

But something like this could be used to support "plugins" to
Pythoncard....

Add....

def	register_plugin (	plugin_name, function_pointer):
	plugin_name =3D plugin_name.upper().strip()
	if register_data.has_key ( plugin_name ):
		if function_pointer =3D=3D None:
			del register_data[ plugin_name ]
			return

		register_data[ plugin_name ] =3D function_pointer
	else:
		register_data[ plugin_name ] =3D function_pointer

I'm typing this from memory, so it looks correct....

The main aspect of the plugin idea is how is the data returned?
With my parser, each plugin returns their own piece of the parsed
text....

So in pythoncard, maybe .......

	plugin =3D a graphical widget?
	plugin =3D complete window?

Just a idea....

Re: [Pythoncard-users] Easy way to get a multi-button dialg box

[Bo G. <bo...@sy...>]

I doubt there is an easy way, not in wxPython. Which brings up an
interesting question. I have been wondering whether sufficient
conditions could exist to migrate 'value-added' widgets like this from
sample code to core Pythoncard. This multi-button dialog is a good
example. I expect code like this would normally be distro-ed as sample
code, but why not make it a core component (or, I suppose more
precisely, a core dialog wrapper)? Is there a policy against
incorporating freestyle components and dialogs into core PCard?
Just curious.

Thanks Benjamin - but I'm looking for a way that allows me an arbitrary 
number of buttons, with labels I choose.
I want to be able to write in code something like:

        result = multiButtonDialog.multiButtonDialog(self, \
           'Dad, can I go to the movies tonight', \
           ['Yes', 'No', 'Maybe', 'Ask me later', 'Ask your mum'], \

I think it does; but I want any number of buttons - not just 3 :-)

It's starting to sound like there is no existing easy way, so I'll clean 
up my code and post it somewhere useful.
And maybe start canvassing Kevin to allow such "utility" functions to be 
included in PythonCard ...

I have not had a need since using Pythoncard to create the exact wrapper
you
are discussing...  I think that WXPython has a MessageDialog that allows
you to
configure the 3 buttons, but I have not looked that up yet...

I just glanced, but did not see any obvious way to modify the
messagedialog in wxpython...
Without possibly customizing a subclass or creating a dialog from
scratch in wxpython....
But I am *NOT* a wxpython guru....

I was good at Tkinter, but got tired of using Tkinter, started to use
wxPython, and held
a "pity" party of myself regarding wxPython documentation, and migrated
to PythonCard...

So I classify myself as "good enough to be dangerous" in regards to
straight wxPython...
