pythoncard-users Mailing List for PythonCard (Page 13)

Hello,
has anybody found out more about this problem? I have the exact same issue,
which renders the layoutEditor useless on the Mac:

Using Alex Tweedy's helpful post ...
http://aspn.activestate.com/ASPN/Mail/Message/PythonCard/2718590
I've managed to implement an editable multicolumnlist called MCL 
(with one deviation from Alex's instructions, in case it's relevant 
to the following -- I edited PythonCard/components/multicolumnlist.py 
itself, thinking I probably want this feature in any mcl I create).
It works nicely, the mixin does it's magic, creates an editor and 
saves edits to MCL.items, but my problem is that it only seems to do 
so after a gainFocus event has been sent to MCL when the editor is 
closed. Consequently, using on_MCL_gainFocus to handle changes is 
unreliable.
I've found a way around this by re-entering and then closing the 
edited cell (the second gainFocus event is now aware of the changed 
data), but it's rather inelegant. I can live with it, as the only 
user of the program will be myself, but if anyone can point out a 
better method, it would be appreciated.

Terry Maloney
 

Ok, here is how it works for me: copy all the *.rsrc.py from the
modules subdirectory to the parent directory. But it is strange and
should not be necessary.

Hello,
I have problems getting the layoutEditor or resourceEditor to work on
my Mac (OS 10.5 Leopard). I have tried 0.8.2 and CVS. The examples work

I found the specific functions I was thinking of:
wx.Window.ScreenToClient
wx.Window.ClientToScreen
So, if you can get the component that your size is relative to, you 
could do:
screen_pos = right_under.ClientToScreen(event.position)
absolute_pos = background.ScreenToClient(screen_pos)
Does that make sense?
I've never done anything like this in PythonCard/wxWidgets, but similar 
approaches in other systems have worked out for me in the past.

Hi:
I am trying to drag an image over other images.
The problem is that the coordiantes I get with event.position are relative
to the component right under, and I would need absolute coordinates, since I
have many images on top of my background.
Any pointers are appreciated.
Is there any sample app that drags an image over something else than the
backgound?
Thanks in advance!

I've got a gui with a text area widget.
I'm running it with the message watcher.
When I scroll the vertical and horizontal scrollbars, no messages are
generated.
Is there a way to enable the scrolling messages?
Is it possible to create event handlers to catch the scrolling?
Does anyone have an example?

Hello:
I have been using commands with menu items before, using model.Background,
and they work fine.
Now I am trying to use a notebook component, and my menu commands are
ignored !?!
I can see the event in the message watcher, but I cannot catch it.
The only sample I've found using a notebook and the menu is in
tools/oneEditor/tabcodeEditor.py
They do not use 'commands' there but they use 'select' on menu items.
1) Is there any difference on commands handling when using a notebook?
2) How do I get the model.Backgound object from an event object within a
page?
In other words: I catch some event in a page, and I want to access some
variables from the notebook, that are shared between all pages.
Thanks in advance!

Now that I've got the 'visuals' working with wxPython 2.7.2.0, I 
added a MultiColumnList to my test app ... I can drag and resize it,
but updates/saves don't stick for size (though they do for 
position) ... it always reverts to (-1, -1) in the Property Editor 
window, and trying to set the size there doesn't work either.
I looked at my rsrc.py file in the code editor, and it turned out 
this multicolumn didn't have a size line:
{'type':'MultiColumnList',
 'name':'List1',
 'position':(19, 500),
 'columnHeadings':[u"['List', Second Title']"],
 'font':{'faceName': u'Lucida Grande', 'family': 'default', 
'size': 12},
 'items':[],
 'maxColumns':20,
 'rules':1,
 },
I added a line 'size':(500, 200),
And it now 'appears' fine in both the running app and the Resource 
Editor ... however the size as reported by the RE's Property Editor 
window remains (-1, -1) ...
Have no idea if this is a bug in RE itself or the MultiColumnList 
component, but fwiw to any one who does.

I'm also using OSX 10.4.11 (PowerPC), so it's probably not the OS, 
but definitely is related to wxPython ... versions up to 2.7.2.0 work 
perfectly, 2.8.0.1 introduces the problem. Unfortunately that's 
probably not going to help Aaron, as 2.7.2.0 doesn't appear to 
support OSX 10.5.

Yes, that did the job.
Thanks!

I would suggest dynamically creating a new tree component in your code

Examples of dynamically creating components are in the dbBrowser sample 
distributed with PythonCard.

I'm having exactly the same problem as Aaron (in both the Layout 
Editor and the Resource Editor), using OSX 10.4.11, with:
Python 2.5.1
wxPython 2.8
PythonCard 0.8.2
Be glad to send my .rsrc.py file as well if it would be of any help. 
But I think the problem may be broader than this: when I open the 
sample app Widgets' .rsrc.py file in Resource Editor, I see only two 
widgets (chkToggleButton and it's associated StaticText, 
labelToggleButton), and the Property Editor window shows only these 
two and one more, labelBitmapCanvas.
(I
just downloaded fresh copies of both the Resource Editor and Widgets, 
btw, to be sure I hadn't screwed anything up in playing around with 
PythonCard ;)
Terry Maloney

I would also need to change the text shown in the root item...
Thanks again!

Hi:
How can I reset a tree component?
I want to be able to add a new root and new children.
Thanks in advance!

John,
I agree, even that I don't know VCL, I've had that experience with 
Java/Swing JPanels. However, it doesn't show up in the .rsrc file, so 
it seems under cover. Any bright stars know where I might look for 
such a panel? or is this misdirected?

With the following versions the layout looks the same as XP, i.e. all 
components are visible and the text area fills the frame:
OSX 10.4.11 (PowerPC)
Python 2.3.5 (as shipped with Tiger)
wxPython 2.5.3.1
PythonCard 0.8.2
So it looks more like something specific to newer versions of the 
OS/wxPython than a platform difference.
Hope this helps.

Sort of - that was my quick and dirty way of ensuring that the loop 
stopped when I wanted it to.
The actual bug I meant was that if you run it and let the loop run to 
completion, it doesn't re-enable the 'Start Loop' button when it's done.
Told you it was rubbish code... :-)

Based on the abrupt, shadow-less edges on the bottom and right hand

Hi Alex,
Resource File attached. My versions:
OSX 10.5.2
Python2.5.2
wxPython 25 (I believe -- MacPorts also installed version 26, but I 
don't think I'm using it.)
PythonCard-0.8.2
Any thoughts appreciated!

Hi Guys,
So I've been toying around with Layout Editor on Mac, and came across 
some weird behavior. I made a "big" window (800 X 600), and I cannot 
see all of it in layout editor on Mac. When I open the same .rsrc.py 
file in Layout Editor on windows, it looks like. Here are sample 
screen shots of each:
Layout Editor on MAC: http://www.cs.bu.edu/courses/cs108/examples/pc-mac.png
Layout Editor on Windows XP: http://www.cs.bu.edu/courses/cs108/examples/pc-win.png
AND: when I actually run the application on Mac, it looks fine. This 
problem is only in Layout Editor/design time. Any ideas?
Thanks!

Well, if it works then fine. Alternatively I'd strongly suggest that you 
install MacPorts. It has clients, Python libraries and even servers for 
most open source databases.
For Oracle and SQL Server you are probably on your own, bearing in mind 
that you will need the client software to connect to either of these 
before you can install the appropriate Python DB module and neither of 
them (to my knowledge) have been ported to OS X.
Have you tried running mxODBC or one of the alternatives?

I managed to get something to work, but it's a bit messy and tied to my 
very simple test application, so for a 'proper' application it might not 
help much.
1. menu.py - since the function doesn't appear to do anything, change from
 def deleteMenuItem( self, aName ) :
 pass
to
 def deleteMenuItem( self, aMenuItem ) :
 self.items.remove(aMenuItem)
 self.DeleteItem(aMenuItem)
2. I then needed some sample code, so I took minimal.py, which has a 
menu with one item and after a bit of experimenting got to this:
-----------------------------
#!/usr/bin/python
"""
__version__ = "$Revision: 1.10 $"
__date__ = "$Date: 2004年04月24日 22:13:31 $"
"""
from PythonCard import model
class Minimal(model.Background):
 def on_textUpdate(self, event):
 currentMenu = self.menuBar.menus[0]
 items = currentMenu.getMenuItems()
 if(len(items)):
 print "Ha! I've deleted your menu item"
 itemToDelete = items[0]
 currentMenu.deleteMenuItem(itemToDelete)
if __name__ == '__main__':
 app = model.Application(Minimal)
 app.MainLoop()
-----------------------------
What should happen is that as soon as you start typing into the text 
area, the exit menu item disappears.
