There's nothing terrible about "import wx"; in fact, it's much better to 
have that than the "from wx import *" that you presumably have right now 
to allow the use of
   self.SetCursor(wxHOURGLASS_CURSOR)

It would be a good thing to change that to
  import wx
and do
   self.SetCursor(wx.HOURGLASS_CURSOR)

Not important - but a good practice to follow.

Thanks, that was exactly what I was missing. I just saw the wx docu says 
it's better to use self.application.Yield() in newer programs. This has 
also the advantage that I don't need to import wx in my PythonCard app.

[Pythoncard-users] How to redraw window in even handler?

[Christoph Z. <ci...@on...>]

Another question. I have an event handler basically like this one:

     def on_button_mouseClick(self, event):
	make component xyz visible
         self.SetCursor(wxHOURGLASS_CURSOR)
         do something that takes some time
         self.SetCursor(wxSTANDARD_CURSOR)

Changing the mouse cursor works fine, but not making component xyz 
visible (it will be only visible after the long operation when the event 
is left again). How can I force PythonCard to redraw the component 
immediately, so that it is visible already during the long operation?

Any help is appreciated.

[Pythoncard-users] PythonCard dialogs can only use 7-bit Ascii?

[Christoph Z. <ci...@on...>]

I'm just making my first steps with PythonCard and I think I like it.

However, I found that most string attributes are converted to 7-bit 
ascii by the resource editor. This makes it impossible to use text 
attributes with international characters like German Umlaute - they are 
simply swallowed.

The culprit is the following code in resourceOutput.py:

     if isinstance(value, unicode):
         value = value.encode('ascii', 'ignore')

After removing it, everything seems to work fine (no matter whether I 
have Unicode enabled wxpython installed or not). So is there any real 
reason that this conversion takes place? Maybe only historical reasons?

Alex,

Thank you for the reply!!

I'm just a python hobbyist which means - I'm not that good, yet :-)

I hadn't considered putting the 'print' statement in the OnDropFiles 
function. How simple!

BTW - I really don't want to print the names of the files. I was only 
using that as an example. I actually want to check:
1). If they're the type of files I want to accept (PDF & Tiff).
2). If the files are Landscape or Portrait.

So now (using your suggestion), I can simply do something like this:

<code>
def OnDropFiles(self, x, y, filenames):
	if checkTheseFiles(filenames):	
		[self.obj.Append(f) for f in filenames]
</code>

Where 'checkTheseFiles' is another function to maybe check the type and 
orientation. Although, I could check the file extension easily enough 
right within 'OnDropFiles'.

Thanks again for the help!!

Bill

Why not simply do this in the OnDropFiles() function,
i.e.

I don't.
However, I think the event mechanism for dropping is different from the 
usual one. If you could simply bind to EVT_DROP_FILES, then I think 
there'd be no need for the SetDropTarget complexity, would there?

However, I do know for sure that the above change works and prints out 
the name of the component on which they've been dropped, and  (just the 
new) file names on a drop event, so it can be used even if you have 
multiple drop targets.

Oops - The above didn't come out correctly. The code (properly indented

[Pythoncard-users] Binding EVT_DROP_FILES to wxList

[Bill B. <bil...@pe...>]

I'm testing out adding drag and drop capabilities to my PythonCard app.
I'm looking to have files dropped onto a wxList.

So far I have code like this:

<code>
class FileDropTarget(wx.FileDropTarget):
     def __init__(self, obj):
         wx.FileDropTarget.__init__(self)
         self.obj = obj

     def OnDropFiles(self, x, y, filenames):
         [self.obj.Append(f) for f in filenames]
</code>

and then later (in my GUI class):

<code>
class GUI(model.Background):
     def on_initialize(self, event):
     self.fileList = self.components.fileList
     dropTarget = FileDropTarget(self.fileList)
     self.fileList.SetDropTarget(dropTarget)
</code>

The above works fine. I can drop the files on the wxList control and the
filenames are appended to the List.

Now, I need to know when files have been dropped on the List, so I added
this line (under on_initialize):

<code>
self.fileList.Bind(wx.EVT_DROP_FILES, self.on_fileList_DropFiles)
</code>

and then later (in my code) I have a method that looks like this:

<code>
def on_fileList_DropFiles(self, event):
     print 'files have been dropped'
</code>

When I drop files on the List, I can't seem to get the DROP_FILES event
to fire. IOW, my program never prints 'files have been dropped'.

Does anyone know what I'm doing wrong?

In case it matters, I'm also binding this event to the fileList:

<code>
self.fileList.Bind(wx.EVT_RIGHT_DOWN, self.on_fileList_RightDown)
</code>

and this event works fine.

Here's my specifications:
OS:             Windows 2000 Pro SP4
PythonCard:     0.8.1
Python:         2.4.1
wxPython:       2.6.1.0

Thanks,

Bill

Re: [Pythoncard-users] Unicode [slightly OT]

[Brian M. <mrb...@gm...>]

You are successfully loading the unicode  u'a\u2019s' into the
variable, s, with no problem other than displaying in a
old-fashioned shell.
The best I am able to do in my Emacs Python shell is
>>> s.encode('cp1252')
'a\x92s'
>>> print s.encode('cp1252')
a\222s

So, I don't get any error with CP-1252.
I think if you want the quote mark to appear as a quote mark,
you will have to work in a more modern GUI window, such as
the Code Editor Shell.

This article "Unicode in Python" by Jason  Orendorff helped
me understand a similar DOS window Python unicode problem.
http://www.jorendorff.com/articles/unicode/python.html
Search the article for the word "unfortunately"  and read from that
point. He concludes with
" So in general it is not possible to determine what encoding to
use with print. It is therefore better to send Unicode output to files
or Unicode-aware GUIs, not to sys.stdout."
I have not found anything to contradict this conclusion.

I found that from the links collected in another good article,
"Unicode Secrets" by Uche Ogbuji May 18, 2005
http://www.xml.com/pub/a/2005/05/18/unicode.html

There are unicode characters (maybe the correct term is codepoint, but
I'm far from an expert) that can not be converted to code page 850,
which the console uses in your case (*).  It is not that obvious for the
apostrophe-like character you have above, but obvious for, say, chinese
or japanese characters if you are using a western windows.

Is that a graphical shell? If so, it probably understands unicode (obviously).

(*) The windows XP console, at least, is able to handle unicode, but
afaik Python uses the ansi apis to write to stdout.

This is caused by the fact that, according to PEP 100, when you try to "print" a
unicode string u, python implicitly calls u.encode(sys.getdefaultencoding()). 

The "recommended way" is to use always u.encode("something") when you print
unicode, but you can try to look at these posts:

http://faassen.n--tree.net/blog/view/weblog/2005/08/02/0

http://www.pycs.net/users/0000323/stories/14.html

to find out how to change the default encoding and why is it considered
harmful.


Hope that helps

Unicode in Python drives me batty.  Every time I think I understand
what's going on, something else strange happens, and I begin to doubt my
comprehension.  So, it's not just you. :)

I get this same behavior on Linux (python 2.3.5).  On that platform,
I suspect (but haven't had time to prove) that the problem is
locale-related.  However, even if I figure it out there, I'm not sure
how that solution would translate to other platforms like Windows.

I suggest writing python-devel with "unicode" in the subject somewhere.
Posts with that subject often get quite excellent replies from Martin v.

Anyone got any clues ?
Does the code editor do something non-obvious that makes this all work 
right when it opens a shell ?
Or is there something additional I could try ?

[I don't really care about what the code editor does - just about being 
able to get my app working, perhaps by doing the same as the codeEditor.]

(for now, I'm working around it by doing
   s = s.encode('ascii', 'replace')
which simply replaces all the odd characters by '?'s - ok for the short 
term, but I do need to figure out a better answer).

Re: [Pythoncard-users] layout and font problems on Windows

[Ronny De W. <ron...@gm...>]

There is indeed a difference with the themes. The examples below are 
with the default Windows XP theme.
When i switch to Classic theme the situation is a little bit better but 
still not good, ie. the mp3player from the
samples shows buttons at the bottom, but only the top half.

I can work around with the 2 tips you gave me, thanks.

However thinking on other people who would like to give Pythoncard a 
try, when they get similar results as the
ones below they will probably stop using Pythoncard, which is a shame. 
PythonCard has potential for becoming
a very powerful and productive tool.

I think we'll need a bit more info from you, on system settings.

When I look at this same window, on a very similar set-up (WinXP, python 
2.4.1, wxPython 2.6.1, pythoncard cvs latest), what I get is

the *overall* window size is the same
the window title bar is smaller
the status bar is smaller
       (therefore the "usable" part of the window is larger vertically)
the font used in the list fields (and presumably in the button also) are 
smaller

I'm guessing the difference is due to different XP "themes" (is that 
what they're called?) and/or different default system fonts. Both areas 
that I know nothing about - but if you happen to know anything about 
them, could you send the relevant info please ?

If you can send that info, I hope to be able to reproduce it here - and 
so confirm that it is a system setting / font issue. That won't mean 
that we'll be able to fix it any time soon, I'm afraid.

The resourceEditor (and indeed most of the samples) do not use sizers, 
and therefore are not able to adapt themselves for differing font 
issues. They also do not specify a font to use, allowing it to default 
to the system font.

Both of these impose limitations between systems - these have largely 
been worked around by adding a certain amount of "slack" in the sizing 
of windows and in the positioning of components, enough for MacOS and 
common Linux variants to work OK.

The long-term fix, I believe, will have to involve the use of sizers. We 
have struggled to find a way to use sizers compatible with the 
simplicity of PythonCard (and will probably continue to struggle for a 
while longer).

If I were you, what I'd do is:

1. make any small work-arounds to make the Pythoncard tools usable on 
your system
2. consider developing any apps  as sizer-based, to ensure they do look 
OK on your system as well as others

For 1, I'd edit (with a text editor) 
{pythoncard}/tools/resourceEditor/modules/proprertyEditor.rsrc.py, and 
change

>           'title':'resourceEditor Property Editor',
>           'size':(405, 270),

to make the size bigger (maybe 450,290)

Note that cvs latest of Pythoncard does contain a simple Sizer layout, 
which can help, though only with fairly simple layouts - e.g. most 
though not all of the samples, and all of the PythonCard tools except 
findfiles (which already uses sizers).
BUT the one thing it does not do is resize the entire window, so it 
wouldn't solve the problem with the resourceEditor. However, you may 
find it useful for your own apps.

Re: [Pythoncard-users] layout and font problems on Windows

[Ronny De W. <ron...@gm...>]

This problem was reported on this mailing list 17-19 dec 2005. Since no 
solution was found i've put the info in a bug record.
http://sourceforge.net/tracker/index.php?func=detail&aid=1415287&group_id=19015&atid=119015

Layout/font problems with resource editor/samples
-------------------------------------------------

I have problems with some of the PythonCard samples, ie. in the 
mp3player the buttons almost completely dissappear at the bottom of the 
window. Another example is minimalList which ads an horizontal scrollbar.

This seems to be a PythonCard problem on my Windows configuration,
my setup: WinXP, python 2.4.2, wxPython 2.6.1.0, pythoncard 0.8.1

some examples:

http://www.5consulting.com/img/tmp/screen1.jpg
resourceEditor Property Editor:
- incomplete button at the right bottom

PythonCard Samples:
custdb: http://www.5consulting.com/img/tmp/screen2.jpg
- overlapping fields

dbBrowser: http://www.5consulting.com/img/tmp/screen3.jpg
- database text field only half visible

minimalList: http://www.5consulting.com/img/tmp/screen4.jpg
- horizontal scrollbar shouldn't be there ?

moderator: http://www.5consulting.com/img/tmp/screen5.jpg
- fonts look too big, ie. "Time Left:" does not fit

mp3player: http://www.5consulting.com/img/tmp/screen6.jpg
- buttons disappear at bottom of the window

I also looked at the wxPython samples and they look ok.

After some searching on the internet i found the following on 
http://www.wxwindows.org/prepare.htm
concerning preparing for wxWidgets 2:
"
Be aware that under Windows, *font sizes will change* to match standard 
Windows font sizes (for example, a 12-point font will appear bigger than 
before). Write your application to be flexible where fonts are 
concerned. Don't rely on fonts being similarly-sized across platforms, 
as they were (by chance) between Windows and X under wxWidgets 1.66. 
Yes, this is not easy... but I think it's better to conform to the 
standards of each platform, and currently the size difference makes it 
difficult to conform to Windows UI standards. You may eventually wish to 
build in a global 'fudge-factor' to compensate for size differences. The 
old font sizing will still be available via wx_setup.h, so do not panic...
"
Does that give any clue ?

How about a Grid, using wxGridCellBoolEditor and wxGridCellBoolRenderer 
to get the checkboxes ?

(note there is a basic grid component in components/grid.py, and a 
sample in samples/simplegrid.py
I modified this by adding

>         mygrid.SetCellValue(1, 0, "1")
>         mygrid.SetCellEditor(1, 0, grid.GridCellBoolEditor())
>         mygrid.SetCellRenderer(1, 0, grid.GridCellBoolRenderer())

to verify the basic idea).

Hi Luca,
you just need to type the commands after the prompt character, which  
should be a % sign followed by a single space. You can ignore the  
machine, directory, and username part of the prompt. I'll make a note  
to change that in the updated install instructions. In addition, it  
appears the directory name was never updated for release 0.8.1, so  
the actual commands you should type are:

cd ~/Desktop/PythonCard-0.8.1
sudo python setup.py install

I think that should do it.

[Pythoncard-users] Polling for ideas regarding list of checkboxes

[Bernie H. <ber...@ut...>]

Hi Everyone, 

I'm trying to create a child window that pops-up a list of things to be
toggled on and off. The list length will not be known ahead of time (think
the little checkboxes next to songs in iTunes). So two things came to mind:
1. ListCtrl with some widget embedded in the cells (seems hard).
2. A scrolled pane.

I don't recall a scrolled pane being a part of pythoncard, but I'm
interested learning how I could implement it and talk to it like a
pythoncard background rather than a wxPython pane.

I'm also interested in other suggestions.

Take Care,
BERNiE

Hi, I follow any instrunctions about the installation
of wxPython on my MacOs X 10.3, but when I install
Pythoncard, the terminal tell me that: "-bash: bob%:
command not found".
Why? I am a beginner in the world of unix command and
I guess I have to change bob in the name of my user.
It's correct?
Thank you for the help.
