There are so many things in the wxDemo I'm not sure which one you mean 
(neither of the two calendar demos I saw seemed to use PopupControl.py)

So I won't answer your question directly, but will answer another, 
hopefully related,  one instead ...

The easiest way to get a pop-up calendar is to create a Custom Dialog, and 
put a calendar control (along with the OK and Cancel) buttons in it. I've 
build a sample version, including a test program that uses it,  - you can 
download it via http://www.tweedly.net/Python/index.html

Note - I did one additional thing: the simple way to select a date is to 
click on the date (so it is highlighted), and then click on the OK button. 
I made it possible to also double-click on a date and that will immediately 
select that date and close the dialog.

Hope that helps - but if not, can you say specifically what example in 
wxDemo you are looking at, and what you want from it that you don't get 
this way.

Thanks

The simple answer is 'not a lot'. In versions of PythonCard up to 7.3 
the relevant code is in model.py. Take a look at the _setIcon method for 
the Background class (in my CVS version it is lines 1180 to 1187);

"""
     def _setIcon( self, aResource ) :
         """Set icon based on resource values"""
         if ('icon' in aResource.__dict__) and (aResource.icon is not None):
             try:
                 icon = wx.wxIcon(aResource.icon, wx.wxBITMAP_TYPE_ICO)
                 self.SetIcon(icon)
             except:
                 pass
"""

The line of interest to you is probably the one where we build the icon 
object by calling wx.wxIcon(). The type specified there is 
wx.wxBITMAP_TYPE_ICO, which if you look at the wxWindows docs is 
specified as a "Windows Icon file".

And that's where my knowledge trickles out I'm afraid. You may get a bit 
more insight looking at the wxWindows documentation for this class;

http://www.lpthe.jussieu.fr/~zeitlin/wxWindows/docs/wxwin_wxicon.html#wxicon

Although I suspect that nothing will get changed for 0.7 it may be 
possible to add an optional type to the icon definition in the resource 
file format for 0.8. That way you could supply and specify a different 
type of icon file.

Before this is going to happen though someone needs to investigate the 
handling of icons and suggest (even better, code) a sensible implementation.

Andy

[Pythoncard-users] wrap popup calendar

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

hi there,

in the wxPython demo there is a nifty popup calendar (i.e. PopupControl.py).

Could someone please give me a few pointers on how I would go about 
wrapping this and making it available in my pythoncard app.

Thanks a bunch,
Selwyn.

[Pythoncard-users] Building Standalone with McMillan Installer

[Joe C. <coo...@ly...>]

To anyone who can help:

	I have been trying to build a "stand alone" .exe file for a program I have written using PythonCardPrototype. In following the instructions from "Building 'standalone' PythonCard Applications" in "PythonCard Documentation" all works fine until I get to the following section.

    --------------------------------------------------------------------------------

(The specification, or 'spec', file is the information used by McMillan Installer to compile and build the standalone version of your application. It's basically a list of the Python source files, Pythoncard resource files and any other stuff that your Pythoncard app needs in order to run properly. To generate the initial spec file, type these commands in a Command Prompt window:

cd C:\Python23\Installer

Makespec.py --icon ..\projects\pimp\pixmaps\pimp.ico
    --out ..\projects\pimp ..\projects\pimp\pimp.py

You should replace pimp.py with the name of the Python script that corresponds)

    --------------------------------------------------------------------------------

    I am using Windows 98 and my Python is in drive D (the full path to the project is "D:\Python23\projects\my_program\my_program.py") so I enter:
cd D:\Python23\Installer

Makespec.py --icon ..\projects\my_program\my_program.ico
    --out ..\projects\my_program ..\projects\my_program\my_program.py

Then I get an Invalid syntax error message:

Makespec.py --icon ..\projects\my_program\my_program.ico
                    ^
    --out ..\projects\my_program ..\projects\my_program\my_program.py

I suspect the problem is in file path differences between Windows and other OS's. I have tried "\\" to replace "\" but to no avail. I could use any help in resolving this problem.

The PythonCard distribution does include a component for Grid - but the 
Resource Editor doesn't include it in the list of components that can be 
inserted (but see below).

The samples directory does include the simplegrid.py - and if you go run 
it, it does seem to work. But the Samples Launcher doesn't include it.

The readme.txt in SimpleGrid says
>This is a work-in-progress sample to test the PythonCard Grid component.

So I think there is a basic Grid component, but there isn't yet any way to 
use all (or many) of its features except by going direct to wxGrid.

The sample dbBrowser2 uses a Grid component (by creating the component 
dynamically).

I think between those two samples you can probably figure out how to do 
include one.
Either
1. sneakily
  - run the Resource Editor to define some of your resources
  - save the rsrc.py file, manually edit it to include a grid (cut/paste 
from SimpleGrid.rsrc.py)
  - now the Resource Editor will let you edit or update the grid component
2. dynamically - as in dbBrowser2.py

In either case, you'll still need to bind events directly, as SimpleGrid does.

Good luck

[Pythoncard-users] calendar samples

[probit <in...@pr...>]

I'am beginner and have problems with calendar component
there are no samples to show how to get any data from it
these are corrupted :( http://aspn.activestate.com/ASPN/Mail/Message/PythonCard/1500742

I try to set Monday as first day of the week:

def on_openBackground(self, event):
self.components.Calendar1.setfirstweekday(Calendar1.MONDAY)

and it doesn't work :(

how can I put date from calendat to TextField?
I tryed

self.components.TextField.text = str(self.components.Calendar1.GetDate().GetDay())

and it works but where is no documentation to describe it :(

(sorry for my english) :)





 

[Pythoncard-users] wxGrid

[Luis M. G. <lu...@gm...>]

Hi there,

I just wanted to know if there will be an implementation of wxGrid in
PythonCard.
I found an old posted message from KA pointing to a couple of samples
(grid.py and simplegrid.py) but these links seem to be broken.

If we can't count with this widget implemented, is there any easy way to
include a grid in a PythonCard app?

[Pythoncard-users] standalone app won't terminate properly when closed

[Tim B. <tb...@bi...>]

I am using a standalone PythonCard app that was generated with py2exe.
The app seems to run allright, but when I close the background by
calling self.close() or just "X"ing the window, I can see in Windows
Task Manager that the corresponding .exe process never terminates. Does
anyone have any ideas about why this might happen?

[Pythoncard-users] using icons in Pythoncard Apps

[Tim B. <tb...@bi...>]

One of my apps is using an .ico file that contains all format
permutations including XP, 256, 16 color and 48x48, 32x32, 16x16 pixels.
When I run the app, windows (xp) uses the proper icon format for each
different manifestation (shortcut, taskbar, even my app's console title
bar...), however the icon in the title bar of my Pythoncard app doesn't
seem quite right. It looks like Pythoncard may have just shrunk one of
larger formats from my .ico file.=20

=20

Can anyone tell me details about how Pythoncard uses the icon file
specified for the background in the .rc file? I mainly would like to
know which size/color formats of the icon file are actually used by the
app.

Well, sometimes I argue with myself ..... :-)

If you just want a simple message, then you can
  - use Resource Editor to create a New / Standard Template with no menus
      (save it as message.rsrc.py)
  - Add a single, StaticText field
  - edit message.py to make the name be MyMessage

Note - this will be a general purpose "message window" so you can re-use it 
for any message for any future apps.

and then put into you main app

from message import MyMessage

and then to show / remove it, do something like

         self.win = model.childWindow(self, MyMessage)
         self.win.components.StaticText1.text = "My new processing ..."
         self.win.SetPosition((200,-1))
         self.win.Show(1)
  # do the real work here
         self.win.Show(0)   # to remove it

Well, you might have looked a *little* harder. On page

http://sourceforge.net/project/showfiles.php?group_id=22307

we see the file MySQL-python-1.0.0.win32-py2.3.zip 
<http://prdownloads.sourceforge.net/mysql-python/MySQL-python-1.0.0.win32-py2.3.zip?download> 
linked. If you downlaod that and loook inside the Zip archive there's a 
document called readme.html which (among other things) says:


      """Installation Notes:


There is no installer - extract and put the files in your 
Python\Lib\site-packages directory.
"""

which couldn't really be that horrible, could it? Impressed that Andy's 
finally put the 1.0 nomenclature on it! It's worth putting up, you'll 
have fun once it runs, honest!

Extra marks if you work out how to put the files in a separate 
site-packages subdirectory using a .PTH file to ensure the module is 
still correctly located for import.

[Pythoncard-users] MySQLdb for Windows?

All the links I found seem to be broken, and the project's home page in

Does anyone have the installer?
Or else, does anyone know how to get it up un running on Windows?

Your problem is that the return from the File dialog is a list of file 
names (so that the user can select multiple files for input - don't think 
that applies for a Save dialog - but the result is still a list of file 
names).

>paths
>         list of strings containing the full pathnames to all files

so you need to do maybe

   myfile - result['paths'][0]
or even
   myfile = result['paths']
   if len(myfile) > 0:
      myfile = myfile[0]

[Pythoncard-users] problem saving file

[Luis M. G. <lu...@gm...>]

Hi everyone!

I have the a problem with the Save file dialog.
What I try to do is serializing a dictionary containing objects with the
Cpickle module.
The name and path of the file should be those entered into the "save file"
dialog, which I created as follows:

def on_save_mouseClick(self, event):
                aStyle = dialog.FILE_SAVE | dialog.FILE_HIDE_READONLY |
dialog.FILE_OVERWRITE_PROMPT
                result = dialog.fileDialog(self, 'Save', '', '', "*.data",
aStyle)
                myfile= result['paths']
                import cPickle
                f = file(myfile, 'w')
                cPickle.dump(student.students, f)
                f.close()


However, when I try to save a file I get is the following error message:

I doubt if you should use a MessageDialog - that's really intended for 
getting input from the user (though you could probably do it).

I'd suggest a ProgressDialog - and if it's going to take long enough to be 
worth putting up a "Processing ..." message, it's probably worth giving 
some progress info to keep the user satisfied.
And in that case, you should consider whether it is feasible, and 
desirable, to allow the user to abort the processing ....

PythonCard doesn't, as far as I know, provide any progress dialog help - 
but you can simply use the ProgressDialog form wxPython directly.

See the wxPython Sample Program (under Common Dialogs). Or, here's a quick 
sample handler for a "Go" button - in this case it does nothing except 
count to 30 seconds (this one allows the user to abort, so not quite as 
simple).

Me neither - I doubt it's in the docs. I was taking a look at the source 
code, to see if there was a different parameter (attribute) to use to pass 
in a string, and found this.

That's why I like Pythoncard - the source is there if I want to look at it.
Not that I can understand it all yet, but I'll get there eventually 
(probably a few days before there's a new release and it all changes :-)

I didn't see that in the Docs...  I'll have to double check, maybe
I missed this...  But....
