Okay, back up and running, thank $DEITY for recordable DVD's....

Now, I have a problem with 0.7.3 when running with python 2.2.2 and wxPython 
2.5. I've installed 0.7.3 from the tarball and wxPython from the RPM on 
wxpython.org.

When I run the resource editor from a command line prompt, I get this:

-----begin-----

------end------

The problem is that at line 309 (line 316 in the code below) of menu.py, the 
value of 'id' is set to -1 when it tries to call self.Enable(). As far as I 
can see, the code in this part of menu.py hasn't changed between 0.7.2 and 
0.7.3, so I'm stumped as to what's going on. I put a bunch of print 
statements into menu.py so it looks like this:

299    def setEnabled( self, aString, aBoolean=1) :
300        print 'setEnabled, aString = [%s], aBoolean = [%s]' % (aString, 
aBoolean)
301        i = 0
302        for m in self.menus:
303            print 'm is now [%s]' % m
304            menuLabel = m.label.strip('&')
305            print 'm.label = [%s], menuLabel = [%s]' % (m.label, menuLabel)
306            if m.name == aString:
307                print 'm.name == aString'
308                self.EnableTop(i, aBoolean)
309                break
310            for mi in m.items:
311                print 'mi is now [%s]' % mi
312                if mi.name == aString:
313                    print 'mi.name == aString, menuLabel = [%s]' % 
menuLabel
314                    id = self.FindMenuItem(menuLabel, mi.label)
315                    print 'found menu id [%s]' % id
316                    self.Enable(id, aBoolean)
317                    break
318            i += 1

When I run with this code, my output is:

I've tried some of the other samples (proof, addresses, etc) and these run 
without any problems, it looks like its just the resource editor in this 
case.

Re: [Pythoncard-users] SetFocus?, redux?

[Kevin A. <al...@se...>]

self in your event handlers refers to your background. self.components 
is a dictionary of all the components on your background. It has some 
extra code that allows you to access each component using "dot" 
notation (e.g. self.components.fldBob) or normal dictionary notation, 
self.components["fldBob"].

setFocus() is a method of each component, so you just call it. For 
example, if the field you want to want to change the focus to is called 
fldBob then self.components.fldBob.setFocus() should do the trick. In 
addition, you'll probably want to call setSelection after calling 
setFocus to select all the text in the field. If you want to save some 
typing you can create a local reference to the component before you 
call the methods.

def on_somebutton_mouseClick(self, event):
     input = self.components.fldBob
     # your validation check code here
     # validation failed so do the focus/selection change
     input.setFocus()
     input.setSelection(-1, -1)

If you use the findfiles tool, you should be able to search/grep the 
PythonCard samples and tools for examples of most of the common actions 
like this. Note that the (-1, -1) convenience values above were added 
to to the underlying SetSelection method long after PythonCard had 
started, so some samples still go to the trouble of calculating the 
number of characters in a field.

[Pythoncard-users] SetFocus?, redux?

[Schollnick, B. <Ben...@us...>]

Okay,

	I have fixed one problem, but I am still attempting to figure out
how to use SetFocus...  And failing...

	I have multiple controls in this PythonCard application, and want
to manually change the focus from one control to another....

	The problem, for me, is that SetFocus (from wxPython) seems to
need to be called from the "control" that you wish to change to.  For
example,
textcntrl.SetFocus (), appears to change the focus to the textcntrl.  (This
was
grepped from the demo directory.)

	But with PythonCard we appear to be operating from the events, not
the controls.

	How would I access a control directly in Pythoncard to call the
SetFocus?

	I found the SetFocus command in the "self" object, but have not
found any
documentation that covers it....

	Does anyone have a small code fragment example?  Or a small test app
example
that you could post?  Because I fear that I am missing something real
obvious...

Very Very Very good point.

I have examined the code quite a bit, but didn't realize that I had
copied a mouseDown handler....

I changed it to mouseClick, and I am getting the behavior that I 
expected.

Talk about a SPE fault.  (Silly Programmer Event)

I've got a hard drive problem on one of my machines - I've got backups so it's 
an inconvenience as opposed to a major disaster, but it means the new RPM's 
won't be ready until the end of today at the earliest. :-(

Re: [Pythoncard-users] Trouble with Pythoncard implementation?

[Kevin A. <al...@se...>]

I'm not entirely sure what behavior you want. I suspect you just want 
to call the setFocus() method on the component you want to select. 
Also, I wouldn't think that you need to use a mouseDown handler, why 
not just handle the check in the mouseClick?

There is no wrapper of the wxPython validation code in the PythonCard 
framework at this time, but I'm guessing it is possible to just call 
the wxPython code directly for validation. I haven't used a validator 
myself, so I don't know for sure.

[Pythoncard-users] Trouble with Pythoncard implementation?

[Schollnick, B. <Ben...@us...>]

Folks,

	I am running into a issue, that I am having difficulty solving.
	(This is my first Pythoncard application....)

	I have the "start" button on my application currently wired to
	check and validate the information given to the application...

--snip--
    def on_BTN_start_activity_mouseDown ( self, event):
        self.operation = self.components.RAD_Operation.selected
        self.servers    = self.components.LIST_Servers.selected
        self.simulation = self.components.CHECK_Simulation.checked == 1
        self.configfile = self.components.TXT_cfile.text

        if self.configfile == "" or self.servers == "":
            bas_wxpython.wxPython_Alert_Dialog ( wxapp = self,
title="Alert!", msg_text="Please specify a configuration file and a server
to process." )
#            wxPython.wx.EVT_SET_FOCUS (self, 
            return ''
        
        if not(self.configfile == "" or self.servers==""):
#            print self.operation
#            print self.servers
#            print self.simulation
#            print self.configfile

            cmd_line = sys.argv[0]
            
            if self.simulation: cmd_line = cmd_line + " -t"
		.....
		.....
		.....
---snip---

	But if I return the focus is still on the button for "start
activity",
	and if you click on anything, the application will not change the
focus
	away from the "start activity" button.  So Pythoncard believes you
	are clicking on "start activity", and report the error again.

	I was thinking of using the wxPython setfocus, but that appears to
be
	fairly complex?

	Any suggestions on fixing this the "right" way, or a simple way?

	Alternatively, anyone have any focus setting samples?

	I did not see any validation code on the pythoncard site, so I
presume
	that there is not a "pythoncard" method for validation?  (I might of
missed
	it.....???)

I could swear this used to work.  I know I tested pretty much every
sample before I released my initial Debian package in August.

I put your fix into my 0.7.3-1 Debian release, so now at least no Debian
users with high expectations will report it. :-)

Debian packages have been uploaded and should start hitting mirrors
within a day or so (perhaps less).  There are no big changes in the
packages from the last release; I'm still building against Python 2.3
and wxPython 2.4.2.4, since that's what I have available to me.

Hmm.  It must be getting late.  I can't remember how the .deb files for
the previous releases got onto the SourceForge site.  Let me know if you
want the .debs for 0.7.3 up there or not.

I updated the online Wiki section related to Debian.  It now says that
the "preferred" method of installing for Debian (in most cases) is to
use my binary packages via apt.  I added a few other details, too.  If
anyone has any comments, let me know.

I didn't notice any problems in my (somewhat minor) testing.

[Pythoncard-users] life.py bug and fix

[Kevin A. <al...@se...>]

I'm not going to put out a 0.7.3.1 release for a bug in one of the=20
samples, so I'm just going to document the problem and fix here for=20
anyone that cares. The bug is already fixed in cvs.

If you're running a version of wxPython prior to 2.5.x then line 99=20
won't work:

                 oldSize =3D self.size

that should be

                 oldSize =3D self.getSize()
=00
=00In addition, Rowland Smith has found that on Linux with wxPython=20
2.4.2.4 the size event is not firing before the idle event. That's=20
actually a wxPython bug as far as I'm concerned (Windows and Mac OS X=20
don't have this problem), but I don't know yet whether this bug exists=20=

in wxPython 2.5.1.5 on Linux. The fix is to add

         self.resizing =3D 0

to the beginning of the on_openBackground handler.

Since nobody on Linux has ever reported this problem before I'll just=20
assume that people running Linux never tried the sample or had low=20

PythonCard is a GUI construction kit for building cross-platform=20
desktop applications on Windows, Mac OS X, and Linux.

Release 0.7.3 includes over 40 sample applications and tools to help=20
users build applications in Python, including codeEditor, findfiles,=20
and resourceEditor (layout editor). A list of changes since release=20
0.7.2 is at the end of this message.

All the information you need about PythonCard can be found on the=20
project web page at:
http://pythoncard.sourceforge.net/

The installation instructions and walkthroughs are available on the=20
main documentation page:
http://pythoncard.sourceforge.net/documentation.html

You can download the latest release at:
http://sourceforge.net/project/showfiles.php?group_id=3D19015

For a list of most of the samples that have been built with PythonCard=20=

and screenshots of them in action go to:
http://pythoncard.sourceforge.net/samples/samples.html

The kind people at SourceForge host the project:
http://sourceforge.net/projects/pythoncard/

If you want to get involved the main contact point is the Mailing list:
http://lists.sourceforge.net/lists/listinfo/pythoncard-users

PythonCard requires Python 2.2.1 or later and wxPython 2.4.1.2 or=20
later. wxPython can be downloaded at http://www.wxpython.org/

Additional Notes:
Remember to backup or just delete your old PythonCardPrototype=20
directory before installing a new version, so that the old files aren't=20=

still in the package directory. If you installed a previous version of=20=

PythonCard on Windows using the binary installer, then you should be=20
able to remove the old package via the Add/Remove Programs Control=20
Panel.

The distutils installer will put the framework, components, docs,=20
samples, and tools in Lib\site-packages or your Python directory=20
(typically C:\Python22 or C:\Python23). Of course, on Linux and Mac OS=20=

X that path will be slightly different and have forward slashes.

Windows users should get a PythonCard menu in the Start->Programs menu=20=

with links to the documentation, samples, codeEditor, findfiles, and=20
resourceEditor.

The tools and most of the samples will now keep their config and data=20
file info in the "pythoncard_config" directory created by the=20
framework. On Unix, the directory will be ~/pythoncard_config. On=20
Windows, the directory varies as described in the following post:

http://aspn.activestate.com/ASPN/Mail/Message/PythonCard/1496793

So, if you run a PythonCard app with any of the runtime tools and=20
select "Save Configuration" from the "Debug" menu, the window positions=20=

and sizes of your runtime windows (Shell, Message Watcher, etc.) will=20
be saved in "pythoncard_config/pythoncard_config.txt" not the=20
PythonCardPrototype directory. Likewise, when you change the text style=20=

used by the codeEditor via the "Styles..." menu item under the "Format"=20=

menu, the modification will be saved in=20

The original purpose of PyTable RDBMS Wrapper (which was originally part 
of the same project as wxoo) was to provide MS-Access-style data bound 
controls.  Afraid I got distracted along the way and turned PyTable into 
a far more general project... and then I got sucked into web database 
programming for a living and did all the PyTable work on that side.

Basically, PyTable turns rows into objects with (introspectable) 
properties, and wxoo includes controls that deal with properties of 
objects, so you can put PropertyControl widgets on your screen, pass 
them a client object (DBRow) and have them provide editing of the 
fields.  At least, that's the theory, as I said, I got sucked into web 
programming in the middle of it.  There's also data grid controls using 
the same machinery, as I recall they were considerably farther along as 
far as being able to properly edit values from the tables and have the 
results committed to the database (the PropertyControl just updates the 
in-memory version, nothing calls updateQuery() on the client DBRow 
automatically).

There's nothing in PyTable for doing table *maintenance* btw, it's all 
focused on the final app, not on providing the GUI database-creation 
mechanisms you get from the MS-Access IDE.

Don't know if that was any help, but at least I got to talk :) .  I love 
talking,
Mike

RE: [Pythoncard-users] DB Framework

[ralph h. <1st...@1I...>]

What I am concerned about are:
--Any Multi user access problems/issues
--Performance running as a network app

I tried using the dbBrowser and got it working for simple table maintenance.  How do you add a delete method and what would the syntax look like?

I wondered if anyone developed a framework for a more elaborate form (non-grid).  I looked at the custdb example but it seems to read the entire table into memory.  I would like to create a ms-access like form with all the buttons.

Look at the dbBrowser sample shipped with the distribution. It talks to 
MySQL, Gadfly, Metakit, SQLite, PostgreSQL and Oracle. It is currently 
read only but would quite easily support insert/update with the addition 
of a few appropriate methods.

As mentioned previously, PythonCard 0.7.2 simply doesn't work with  
wxPython 2.5.x, so unless you're using the version of  
PythonCardPrototype in cvs, do not upgrade yet.

I hoped to release 0.7.3 today, but I just realized that some of the  
additions I made in the last week to support Python 2.2 properties  
actually won't work with wxPython 2.4.x so now I have to comment out  
all those changes in model.py, widget.py and the samples and tools and  
go back to the old way which will work with both 2.4.x and 2.5.x or  
find some other workaround, sigh. Consequently, I probably won't  
release 0.7.3 until Monday.

IIRC there's actually a database demo for Gadfly. You ought to be able
to adapt that to MySQL fairly easily - the gadfly module isn't quite
DBAPI 2.0 compliant, so there would be a slight impedance mismatch, but
techniques for working with MySQL in Python are fairly well-established.

The short story is that the List component doesn't support 
multi-selection. This comes up periodically on the list, but nobody 
seemed to want it bad enough to resolve the issue before.

To get that you would need to subclass the existing component and 
change the style in the __init__ method. This is best done by creating 
a new module as well and either sticking it in the 
PythonCardPrototype/components directory or an appcomponents directory 
in your app directory. If the latter, you also need a file called 
__init__.py in the appcomponents dir for import purposes.

The underlying wxPython control, wxListBox has three mutually exclusive 
styles: wxLB_SINGLE, wxLB_MULTIPLE, and wxLB_EXTENDED. The existing 
control could probably be changed to allow one or both multi-selection 
styles but I don't want to make that kind of change this close to a new 
release; 0.7.3 should be out this week.

We have to decide whether List should support multiple selection styles 
or whether there should be a separate component, perhaps called 
MultiSelectionList or something. PythonCard has some components that 
are subclasses where we made a separate component for a different 
style: TextField, PasswordField, TextArea, but we also have some 
components where we just have an attribute to change the style. If we 
support multi-selection in List then we'll need to add some additional 
methods that deal with lists/tuples for changing the selection. We also 
have to test whether it will break the existing attributes that get the 
selection since they might end up returning a list/tuple when the user 
code was expecting a single value. That just needs some experimentation 
and then testing.

[Pythoncard-users] wxgrid trouble

[Selwyn M. <sel...@pa...>]

hi there,

I am trying to implement a pull down menu within a wxgrid, as is shown 
within the wxpython demo (GridCustTable.py).

However, I am unsure how to translate the column formatting to pythoncard.

In the wxpython demo they create a custom table which specifies the 
column type as:
wxGRID_VALUE_CHOICE + ':choice A, choice B'

-which is basically what I want.

After scanning the namespace of pythoncard's simplegrid example
I see that wxgrids have a SetColFormatCustom() but am unsure how to 
apply the above to it.

Any help greatly appreciated.

Is there anyone using PythonCard with SuSE 9.0?  I have everything needed 
(AFAICT), like wxPython and all that...but as usual I am having some trouble 
figuring things out...SuSE has its own way of doing things.  So,  HELP! :-)

Thanks,

Or you could do something like this:

def on_close(self, event):
    import os.path #if you haven't done before
    if os.path.exists('closer.dat'):
        return
        # or
        #pass
    else:
        event.Skip()

Which is maybe cleaner and faster. Haven't tested.

After checking with Thomas Heller, I've change the setup.py script to
support py2exe 0.5

from distutils.core import setup
import py2exe

setup( name = "minimal",
       console = ["minimal.py"],
       data_files = [ (".", ["readme.txt", "minimal.rsrc.py"]) ]
       )

Thomas suggests looking at the py2exe examples for more elaborate builds.
Perhaps someone can make suitable scripts for all the tools which we can
include with release 0.8 (sometime after 0.7.3)?

After trying a test with Ruben I decided to remove the PyCrust import
support for wxPython 2.4.0.7 and earlier in debug.py. This seems to clear up
the above warning message. PythonCard 0.7.2 and 0.7.3 will still work with
wxPython 2.4.0.7, you just won't be able to use the shell.
