[Pythoncard-users] Two Pythoncard applications

[Jussi S. <jus...@pp...>]

Apologies for the long post! I've made 2 applications that could 
interest others also.

1. Blood Pressure Monitor (BPM)

BPM is a PythonCard application for storing values of blood pressure 
measurements and for producing PDF charts of those values. The chart can 
be used by the physician of a patient to control the effect of the 
medical treatment being used.

Despite its rather pompous name BPM is a modest, simple to use program. 
All it does could probably have been accomplished easily  by a couple of 
Office macros, but I'm only willing to use tools that include Python or 
at least Py in their names.;)

The purpose was to make
- the data entry fast but still ensure the validity of the data
- the charting in the ideal case happen with a single mouse click

BPM produces a one-page PDF file containing:
- the 'traditional' date-oriented systolic and diastolic pressure graphs
- the scatterplot of (systolic, diastolic) pairs
- the BP value distribution as a bar chart with BP values as X-axis and 
the frequencies of those values as Y-axis.
- the quartiles Q1-Q3 for systolic and diastolic pressures

After that BPM starts Acrobat Reader giving it the name of the file 
produced. The chart can then be viewed and printed or e-mailed as need be.

BPM could serve as an example for developers using Pythoncard of how to 
use wx.Notebook and wx.Grid with Pythoncard. It might also be an example 
of how to do things the hard and wrong way, because part of what I've 
accomplished has been the result of trial-and-error.

Some of the things I would have liked to been able to do I couldn't. For 
example, I would have liked to make the first field 'sDay' of the second 
tabsheet 'Data Chart' to be active when coming to this tab the first 
time after the start and yet to have the first tabsheet 'Data Entry' and 
preferably the (0,0) cell of the grid in it be active. Trying to do this 
resulted in a perverse condition where I had activated the 'Data Entry' 
with 'stringselection' and yet the input focus was in the 'sDay' field 
in the hidden tabsheet 'Data Chart'!


2. A Trick Card Game

This card game belongs to the "plain trick games without trumps" 
category. I'm not aware of its name, so I'll have to describe its rules. 
The game is simple so it is particularly suitable for children.

One player plays against 3 computer players. Each player is dealt a hand 
of 5 cards. A round consists of each player in turn playing one card.

The suit of the leading card determines the suit to play in that round. 
If the player has cards of that suit, he has to play the suit but he is 
not forced to use a higher-valued card. If the player does not have the 
leading suit, any suit can be played. The player with the highest card 
of the round's suit wins the trick getting 1 point.

The game comes with UIs defined for two languages, English and Finnish, 
and with description on how to translate the UI to some other language.


3. Environment and download

The programs have been developed and tested on Windows XP Home SP2 using 
the following great software: Python 2.4.3, wxPython 2.6.3, PythonCard 
0.8.2, PyChart 1.34 and Acrobat Reader 7.0.8. They have a non-essential 
Windows dependence of using winsound with error messages.

They are distributed under the MIT license (see the attached file

[Pythoncard-users] Maximized window

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

I have an interesting window problem. My pcard rsrc sets the window size 
at 700x500. When the program runs it it maximized to full screen 
(1152x864). So it seems to ignore the program setting. This seems to be 
related to other programs, because it has worked before, but does not 
work after running some other programs. Why doesn't the pcard routine 
control the window size like it's supposed too?

Thanks Kevin....I'll have to get the latest pyInstaller and find out if 
that makes a diference. In the meantime I've commented out the print 
statements and left the code in place to write the strings to a text file.

That sounds more like a bug in McMillan to me. Have you tried using  
the updated pyInstaller instead? Maybe it is changing where  
sys.stdout and sys.stderr go? You could add some fields to your  
application and dump the values for both of those. You could also  
assign some other file-like object to sys.stdout. You could make your  
own that even dumps text on a write to a hidden TextArea field which  
might be a temporary workaround until you figure out the real  
problem. Alternatively, assign a real file handle to sys.stdout or  
sys.stderr and capture the specific tracebacks that way. Just a few  
ideas to help debug the problem.

[Pythoncard-users] Standalone PythonCard applications & no console

[XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]

I'm still building Windows EXEs via the Mcmillan installer that I set-up 
quite a while ago (I'll get standaloneBuilder one of these days!) and I 
still use that old debugging technique, the print statement, all the time.

For some reason I had assumed that switching the standalone config file 
from console to no-console would make no difference if I left the print 
statements in place, i.e. the standard output would just get directed to 
NULL or something. However I just tracked down a problem I was having to 
the fact that with the console switched off but the printing still 
active my PythonCard app was stopping halfway through processing a 
button press and control returning to the event loop. The issue would 
not affect every PC the application was running on but when it happened 
it was always in the same place.

I presume printing to no console is therefore "a bad thing" and the 
standalone build mechanism isn't capable of redirecting standard output 
with no console - could anyone confirm this?

It also makes me wonder what happens to standard error output, e.g. 
exceptions. Traditionally they get reported to the console - in 
"non-console mode" could this also trigger issues (presumably in most 
cases the exception occurring in the first place is probably a bad sign, 
but sometimes you might be able to recover)? Do I need to make sure that 
any error output is blocked off as well or logged to a file?

I feel a bit of an idiot for taking so long to realize what now seems 
pretty obvious, but I just wanted to make sure I am now correct and that 
there isn't something else weird going on with my application and this 
standard output business is just a red herring.

[Pythoncard-users] PythonCard application compiled executable

[John R. <joh...@ho...>]

It would be nice to be able to run a PythonCard
application on a Linux box which does not have
PythonCard or even Python installed. Particularly as
the equivalent has been done to allow an app to be run
a Windows box.
PS Freeze allows a Python module to be compiled.
However, to do this for PythonCard would need the
interpreter from PythonCard to be included with the
rsrc.py & py files in the app.

John

The other option is to do it when you create each page of the notebook, for 
example assuming you have a notebook component called 'myNotebook' and you 
want to add 4 tabs and end up with the 2nd tab selected, the relevant parts 
of the code would look like this:

self.components.myNoteook.AddPage(tab1, 'Tab #1', False)
self.components.myNoteook.AddPage(tab2, 'Tab #2', True)
self.components.myNoteook.AddPage(tab3, 'Tab #3', False)
self.components.myNoteook.AddPage(tab4, 'Tab #4', False)

It's the True/False parameter on the end which governs which tab is made 
'active'.

Re: [Pythoncard-users] Notebook question

[Jussi S. <jus...@pp...>]

You can also use (the more application oriented way?):

   self.components.notebook.stringSelection = 'Data Entry'

where '...' ( 'Data Entry' in my case) is the text in the notebook tab.

Simply change the selection attribute of your notebook:

self.components.notebook.selection = 0

That's assuming your notebook component is named 'notebook'.

Check out this reply from last year

http://article.gmane.org/gmane.comp.python.pythoncard/1346/ 
match=childwindow

The event handler you are creating the child window in has to finish  
executing before you can be sure that the underlying C++ control has  
"settled". The purpose of the on_initialize event for a background is  
to avoid all the nasty bugs that can occur on the different platforms  
if you try to do certain operations on controls during the underlying  
initialization. As Brad mentioned, you can get data from the parent  
window, but often what you'll want to do is simply use wx.CallAfter()  
to set additional variables, call other methods, etc.

You can't, as far as I know. It would be a nice feature
to add, but you can have the child window
request data from the parent via self.getParent().

Also, you can't use __init__ for PythonCard classes, you
have to use on_initialize; I recall that was due to
timing issues but someone else can probably explain
better.

[Pythoncard-users] Proper way to invoke child window

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

Hi list,

What's the proper way to pass parameters to child
window?

For instance, if I do:

cw=model.childWindow(self, childWindowClass(a, b))

and it appears I can't expect that the __init__
routine in childWindowClass be:

class childWindowClass(model.Background):
   def __init__(self, a, b):

So, what exactly should I create childWindowClass
with?  I've been doing it with no parameters and then
try to set the parameters of the child window
afterwards but that's really ugly.

How should I pass parameters to a childWindow?

Thanks,

I'm not sure if this is a PythonCard question or an Eclipse question :-)

Here's what I do know ..... the layoutEditor will accept a resource file 
name as its (only) command line argument.

For instance, (in Win XP)

open a shell box (aka DOS box)
give the command (for me)
    pythonw c:\python\PythonCard\tools\resourceEditor\layoutEditor.py 
samples\flock\flock.rsrc.py

and it opens the layout editor and then opens the resource file for the 
flock sample.

So if there's a way to append the resource file name to the command line 
from Eclipse, you should be OK.

I just spent a couple hours wondering the same issue. The solution is to

 in your independent PythonCard application that is to become a tabsheet

On all platforms, you can get to the documentation via the PythonCard  
Documentation menu item under the Help menu in the codeEditor,  
resourceEditor and Debug menu if you have any of the debug tools  
turned on. In addition, if you installed onto a Windows box you  
should have a Programs group with a link to the docs.

If this isn't working for anyone on the various platforms (Mac,  
Windows, Linux) then we need to update the code that attempts to find  
the documents locally before linking off to the main web site, so  
please let us know.

[Pythoncard-users] Using Notebook

[Wesley P. <bu...@ya...>]

I have written some scripts fashioned after the testNoteBook.py routines. However, when I select a tab, the child window opens but is not inside to the main window. The code is shown below: 

  class MFMNote(model.Background):
  
    def on_initialize(self, event):
  self.components.notebook.SetMinSize(self.size)
  self.singleItemExpandingSizerLayout()
   
  
  panel1 = wx.Panel(self.components.notebook, -1)
  self.components.notebook.AddPage(panel1, 'test1', True)
   
  
  panel2 = model.childWindow(self.components.notebook, test2note.test2)
  self.components.notebook.AddPage(panel2, 'test2', True)
  The testNotebook samples run fine.
