[Pythoncard-users] transparency in a python card app...

[Alec B. <wry...@gm...>]

I'm trying to place either a PNG or GIF with transparency on a PythonCard
application. I've converted the image I'll be placing to RGBA, but still
when I place it, it has no transparency.

I'm trying to place this transparent image on top of another image that's on
the stage as an Image component, and it has no alpha channel, though
assigning one doesn't seem to help.

Is there some trick to this that I'm missing?

[Pythoncard-users] drag'n'drop

[fabio n. <na...@po...>]

hi guys! and first of all, many many thanks for this great piece of
software, i mean pythoncard.

i would like to add drag'n'drop capabilities to my pythoncard powered
gui application.

precisely, i wish i could drag and drop an image file icon into my gui
window and so have the image filename registered in a list.

is it possible with pythoncard? am i forced to use wxpython directly?
is there any sample applications or any drag'n'drop howtos out there
on the internet?

many many thanks in advance!

[Pythoncard-users] No module named PythonCard

[Julian B. <ben...@ll...>]

  I am testing PythonCard by issuing:

   /usr/share/PythonCard/samples/minimal/minimal.py

I get error messages:

question: any possible cause for the errors and is PythonCard 
itself  binary? I could not find it.

[Pythoncard-users] displaying video?

[Alec B. <wry...@gm...>]

Is it possible to display video within a PythonCard application?

Re: [Pythoncard-users] Installation problems

[Dan F. <dan...@gm...>]

start cmd and then run minimal.py so you can see the error message.

in site-packages you should have a folder like this: wx-2.8-msw-ansi , and a
wx.pth file and wxversion.py
when installing wxPython, you should check that the installer has detected
the correct installation path of Python.

that's all i can say :)

Re: [Pythoncard-users] PNG Transparency in Standalone EXE

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

You're probably going to have to ask on the wxPython list. This might  
be a 2.6.x issue or possibly a different DLL is getting used with the  
EXE and it doesn't properly support transparency with PNGs. At a  
minimum, you'll need to do some debug dumps of what is getting used  
on the different runs so you can verify the version of Python,  
wxPython, etc.; simply running the executable with the -s or -d  
option might be good enough for that.

[Pythoncard-users] PNG Transparency in Standalone EXE

[Phil E. <ph...@li...>]

Hi All:

I'm written a short program for use at work - both the target and development 
platform is WinXP and I have Python 2.4, wxPython 2.6.3.2 and PythonCard 
0.8.2 on the machine where I'm writing/testing the code.

The program has the company logo displayed on the UI in the form of a 
transparent PNG graphic in the bottom right corner of the panel. The logo 
displays perfectly when I run my code either from a DOS prompt or by a 
double-click on the .py file in explorer.

When I package the program up into an EXE, using standaloneBuilder, the 
resultant executable does not display the graphic correctly. It shows up with 
a black background instead of transparent. I get the same result regardless 
of whether I use pyInstaller or py2exe to do the conversion to EXE, which 
suggests to me that the problem may be due to the altered execution 
environment that is present when running a standalone application.

Problem is, I have absolutely no idea where to start looking to troubleshoot 
this - can anybody offer any suggestions to get me going? The only thing I 
was able to think of was explicitly setting the background colour on the 
Image component so it matched the colour of the panel, but this didn't make 
any difference.

I tried another method in Eclipse. I got it to work. So this problem is solved.
I do not know the solution to the above problem, but I do know how to make
py2exe work from Eclipse.

Rafael,

PythonCard relies on the wxPython library, which in turn relies on the 
wxWidgets toolkit. If they are ported to native Mac then you are in 
luck. I'd suggest asking on the wxPython users list which you can 
subscribe to here;

[Pythoncard-users] A native, Cocoa Version of python card?

[Rafael B. <be...@sb...>]

Hello,

The purpose of this e-mail is to inquire as to whether a native,  
Cocoa version of python card for the Macintosh is due to be released.  
I am very interested in learning python card on the Mac, but my  
problem is that, since I am blind and therefore must use a screen  
reading utility (VoiceOver) that is not compatible with Carbon  
applications, I don't think that I can use the current version of  
python card. So, I am really hoping a Native Cocoa version is in the  
works.

Cordially,

[Pythoncard-users] py2exe

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

Folks,

I have looked at the tutorials and "googled" for problems similar to mine.
No luck with any of that. Here's a thought. The solution to similar problems
has been to have

from PythonCard.components import textfield
as opposed to


from PythonCard import textfield
This won't work for model, resource, and util because they are not named
components in Pythoncard. From my searching on google, obviously people are
having sucessful builds with pythoncard and py2exe.

[Pythoncard-users] Set the background and foreground colour of a gauge component

[Russell E. <rus...@gm...>]

Hi,

I am trying to set the foreground and background colours for a gauge
that forms part of a system performance monitor that I am developing
using PythonCard.  The colours (colors) are being set within the
Resource Editor but appear to be ignored.  When I try setting them
explicitly by using self.components.Gauge1.foregroundColor =3D colour,
then that is being ignored too.

Any assistance would be appreciated.

Thanks.

self.visible = True seemed to do the trick from the taskbar, however if 
it's behind another window I'm not so sure. You could minimize to the 
taskbar and then raise it, I suppose.

*If* I had my wxWidgets documentation around I'd check...sorry.

Lists in PythonCard are list any other Python lists,
and all the usual list comprehensions and methods work
just fine. Example:

If myList is the list in question and
"string_in_myList" is an element of the list, then

listIndex = myList.index("string_in_myList")

will assign the index of "string_in_myList" in myList
to listIndex.

Enjoy!

[Pythoncard-users] Get selected Item in List

[Kwasir <kw...@gm...>]

Hi everyone!

Can someone give me a hint how to get the ID of an selected Item in a 
list? Currently I do have a list and and adding is no problem. But when 
I select an Item, I do not find any method in the documentation, that 
gives me the ID of the current item, so that I
can do "List.delete(self, aPosition)".
So there should be some method which returns the aPosition, or a property.
Am I too tired to see it?

Thank you!

Re: [Pythoncard-users] alternate icons

[hwg <hw...@ya...>]

I have got this to work for changing the icon that appears in the title bar and in the taskbar in Windows:

import wx

class MyBackground(model.Background):

        ib=wx.IconBundle()
        ib.AddIconFromFile("my.ico",wx.BITMAP_TYPE_ANY)
        self.SetIcons(ib)

I believe the icon has to be an icon file, not just a bitmap.  There are several freeware icon editors around.
