Re: [Pythoncard-users] PythonCard status (was Re: Odd behaviors of Pythoncard under Ubuntu: errors on exit, StaticText over BitmapCanvas, multiple item move)

[Morgan V. <ve...@gm...>]

Hi again,

Update on my previous report:  I tried the Layout Editor (rather than
Resource Editor) under Ubuntu and most things work.
Under Ubuntu I cannot move Buttons or Choice boxes individually, but
if I select them with a text box I can move them together, which is
silly, but deal-with-able.  Seems like some underlying class issue in
wx->GTK?  I don't have a complete catalog of all the components which
are movable versus not.

Another thing that cropped up is that whenever I select an item in the
Layout Editor, it moves downwards by about 30 pixels.  Odd.
Under Windows, every select moves the item down and right by 2 pixels each.

But at least multiple select works!


cheers

I hope it's still being used by quite a lot of people, but it's difficult to tell because the list is so quiet. Kevin has mentioned on the developer list that he's recently tested PythonCard with Python 2.6 and the latest wxPython, and he's going to try and look at one of the Mac-specific issues I mentioned recently.

It's the usual problem though - people have other priorities and I suspect 0.8.2 is good enough for many. I'm using it quite a bit at the moment for simple utilities and I'm trying to learn more about the inner workings because there are some more complex projects that I might be able to use it for in the future. I'm also trying to contribute something back at long last by attempting to duplicate issues other people are finding and if possible doing a bit of debugging. Without knowing how many people are still using PythonCard I don't know whether it'll help anyone or just help satisfy my inner-geekness.

It would be good to blow the dust and cobwebs off the bug/suggestion/to-do lists, and get the project rolling, but we need to know who can help and if it's worth it, i.e. who is still using it.

Maybe to start with, since the list is so quiet, we can do a poll and get an idea of numbers, platforms/versions being used, a top 3 bug/request list and who can contribute? Any takers? I'll start it off if nobody else does....first though I need to go around and work out how many combinations of OS + Python + wxPython I have!

> Is there any comprehensive documentation on PythonCard?

Other than the stuff on the web-site, I tend to rely on examining the source code and when necessary the "wxPython In Action" book.

Fair enough....I've got into a routine of copying existing projects, altering the GUI in the resource editor and then changing the behaviour in the code editor. I really should take a look at the layout editor one of these days.

My target platform is Windows and I'm building .EXEs, so my Mac doesn't get used much with PythonCard other than trying to duplicate platform-specific issues that others have discovered on this list. There are still problems (like the CoreGraphics single device context limit in wxPython 2.8.x) and it doesn't look like the GTK platforms are smooth-sailing either.

It is kind of in limbo. What it does, it does (more or less) adequately. 
There is a lot more it could do (i.e. addiitonal component types, better 
features in the editors, sizers via the editor, ability to mix in 
additional initialization characteristics, ... lots of additional things 
it could do), but unless someone is really motivated by a need for 
something specific, and has time to delve into developing it, I don't 
see any prospect of those being done.

I'm not sure there is anything I'd describe as comprehensive 
documentation. There is a fair amount in the docs directory, and the 
samples contain lots of useful info, even though not 'documentation' as 
such. And if you haven't used it, the findfiles tool is a good way to 
find things in the samples, as well as being a generally useful tool anyway.

See samples/minimalList - it creates its columns using

>         list.InsertColumn(0, "Artist")
>         list.InsertColumn(1, "Title", wx.LIST_FORMAT_RIGHT)
>         list.InsertColumn(2, "Genre")  

Don't know offhand about the font type, but there should be a similar 
direct call into wx to do it. Or, it may not be possible to set the font 
for each column (I don't see a wx sampel that does this, with a cursory 
look). You may need to use a grid rather than a list .... but an explore 
of the wx samples or docs should sort that out for you.

'size' - column size or font size ?
column size is set by list.SetColumnWidth() - see further down in the 
same sample.

I'd use the layout editor in preference to the resource editor. It was 
intended to be a replacement for the older (single-component) version, 
and as far as I know has no significant problems that would require you 
to use the older version. There may be issues with component order on 
the Mac, but I think they were all resolved.

Actually, it was intended to be a first step towards a combined editor 
that would incorporate both resource/layout editing and code editing - 
but that was much too big a problem for me, so I stopped at making it a 
better layout editor, incorporating the features I thought were most 
needed. I made some efforts towards incorporating sizers (but never 
succeeded in getting them anywhere near to right). Someone else did do 
some work on a sizer based editor - but at the time I was unable to even 
try it out, so I don't know how far that effort got.

A couple of years ago, I made a switch from PC to Mac, which was 
absolutely disastrous for Python use, so I never did get Python + wx + 
Pythoncard to all work adequately, and was effectively unable to do any 
Pythoncard work for quite a long time. I have now switched back to a PC, 
so I can at least run the tools and look at things; but I still have 
relatively little (i.e. almost no) time to do any programming, so I 
can't realistically offer much hope that I will do significant 
development on Pythoncard any time soon.

Could be a bug. I can place StaticText over a BitmapCanvas without any issues on XP, but on my old OpenBSD box (Python 2.4 + wxPython 2.6.3) I see the same problem, plus I cannot change the background colour of the StaticText component. Maybe a GTK2 issue?

I think we're on the same wavelength :-) You're saying that you can do multiple selection in the PythonCard resource editor, yes? Because I can't...

...got it. It works in the layout editor...which I haven't got around to using much yet. But not in the resource editor.

There could be a communication issue here; I understood the reference was to
selecting and moving multiple components in PythonCard, not in the
subsequent live application. In PythonCard, when developing the application,
it can be done. I am using Python 2.6 and the latest PythonCard version.

Hmmm....doesn't work here on XP (Python 2.3 - 2.6 + wxPython 2.6 - 2.8). Control-click just selects one at a time, and no click-drag rectangle appears :-(

Hi,
I use Python and PythonCard on the Windows (XP) platform so I can answer
Item 3; yes - in Windows simply draw a rectangle with your mouse around the
components (or Ctrl-click) to select multiple items and drag them in unison.

I have a few questions of my own that I would like to throw out to
the broader PythonCard community.
1. I have attempted to establish what the status of PythonCard is (without
success), because the project appears to have terminated some years ago.
Does anyone know? Is there any comprehensive documentation on PythonCard?
2. I have a particular problem; does anyone know how to right-align a column
in a multi column list in PythonCard? In commercial systems this is a common
requirement. Similarly, is there a way of setting the font type and size for
a particular column in a multi column list?

Regards,

Andrew.

[Pythoncard-users] Odd behaviors of Pythoncard under Ubuntu: errors on exit, StaticText over BitmapCanvas, multiple item move

[Morgan V. <ve...@gm...>]

Hi all,

Item 1:
I'm having a hard time getting PythonCard to run cleanly on my Ubuntu
machine, seeing some peculiar errors that keep my program from
terminating properly on exit.  Things generally work okay (the
resourceEditor is a disaster area, but I've managed to get what I need
done) but exiting any app spits out a bunch of errors like the
following:

[from exit of Minimal.py:]

me@mylocalhost:~/somepath/$ python minimal.py

(python:29257): GLib-GObject-WARNING **:
/build/buildd/glib2.0-2.16.6/gobject/gsignal.c:1741: instance
`0x165c380' has no handler with id `224'

(python:29257): GLib-GObject-WARNING **:
/build/buildd/glib2.0-2.16.6/gobject/gsignal.c:1741: instance
`0x139f510' has no handler with id `121'

(python:29257): GLib-GObject-WARNING **:
/build/buildd/glib2.0-2.16.6/gobject/gsignal.c:1741: instance
`0x139f030' has no handler with id `49'

In this case all I did was run Minimal.py, and exit it.
I get similar errors when I run any other PythonCard application.

My installation is... complicated.  Multiple versions of things, some
from Synaptic, others not.

I'm running Ubuntu 8.04.
Python 2.5 (but older versions are installed too)
PythonCard 0.8.2, installed via the setup script in the tar.gz
PythonCard 0.8.1, installed via Synaptic (installed 0.8.2 before i
realized there was a package)
libwxgtk2.6-0,  via Synaptic
libwxgtk2.8-0,  via Synaptic

I deleted the 0.8.2 version of PythonCard, but the problems persist.
Are the multiple versions of libwxgtk part of my problem here?



Item 2:
It appears to be impossible to get a StaticText widget to render in
front of a BitmapCanvas.  I need to use some bitmapcanvases to show
colored areas behind my interface.  No matter what the order of the
items is in the resource file, the static text ALWAYS renders behind
the BitmapCanvas.
Other widgets like buttons, gauges etc all render fine, according to
order in the file.

Bug or Feature?

[the semantics of "Front = behind everything" and "Back = in front of
everything" puzzle me, but whatever.]

I know I can work around it by drawing that text in the BitmapCanvas
itself, but this seems pretty wrong.


Item 3:
Is it possible to select and move multiple items together?  This
doesn't work in Ubuntu AFAICT.
Is this implemented/working on any other platforms?


Thanks!


I'm still super-stoked on how easy it's been to put together a basic
interface for this application -- I migrated my entire project from
Ruby into Python so that I could use a reasonable GUI toolkit.  Just
trying to clean up the loose ends so other people can run it and not
throw errors all over the place!

Re: [Pythoncard-users] Idle handler only runs after an event?

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

In wx terms, idle just means the event queue has emptied, which is  
why you see "idle" events occurring when you move the mouse. Using an  
on_idle handler in PythonCard is one way of updating your UI as it  
allows you to do some processing without worrying about whether an  
event generated from a sizer, window resize or some other update is  
still processing.

For an application using threads such as yours you'll be better  
served by using a timer event. There are numerous examples of this in  
the samples as well as a timers-threads.html documentation at http:// 
pythoncard.sourceforge.net/timers-threads.html

You can use a timer that fires more often than you require for  
processing along with a flag to prevent running code within your  
program unless it is required. For example, in the worldclock  
example, the text on screen isn't updated unless the time has changed.

I'm sure some folks would be interested in seeing your program if you  
want to provide a link.

[Pythoncard-users] Idle handler only runs after an event?

[Christopher L. <chr...@ip...>]

Hi all.

I'm just writing a GUI frontend in Pythoncard that uses queues to
communicate between threads. The Idle handler reads the queue and
updates some information in the GUI.

The issue I'm finding is that the GUI information only updates when I
move the mouse within the Pythoncard window. I don't know if it's just
the GUI that's not updating, or if the Idle handler isn't actually
running.

Is this a known issue? Is there any sort of viable workaround? I am
running Ubuntu 8.04 with both libwxbase2.6.3.2 and libwxbase2.8.7
installed, Pythoncard 0.8.1-8, Xorg 7.3, and Python 2.5.2. I can provide
any other information you want or need.

For those interested, it's a frontend for a CLI program I wrote that
converts video files to the correct format for Sony Walkman MP3 players.
Uses multiple cores as well!

Chris

Hmmm....looks like another issue that arrived with wxPython 2.8.x. I created the following non-PythonCard application:

import wx

class DemoFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self,None,-1,"Test",size=(400,400))
        
        self.list = wx.ListCtrl(self,-1,style=wx.LC_REPORT,size=(300,100))
        self.list.InsertColumn(0,"Column1")
        self.list.InsertColumn(1,"Column2")
        print "__init__:\nList GetBestSize: ", self.list.GetBestSize(), "Current: ", self.list.GetSize()
        
        self.button = wx.Button(self,-1,"Button",pos=(200,200),size=(100,50))
        print "Button GetBestSize: ", self.button.GetBestSize(), "Current: ", self.button.GetSize()

app = wx.PySimpleApp()
frame = DemoFrame()
frame.Show()
app.MainLoop()

and ran it on a few platforms:

OSX 10.4 + wxPython 2.5.3.1:
List	GetBestSize: 100,80	Current: 300,100
Button	GetBestSize: 70,20	Current: 100,50

OS 10.4 + wxPython 2.8.9.1:
List	GetBestSize: 300,100	Current: 300,100
Button	GetBestSize: 70,20	Current: 100,20

XP + wxPython 2.8.9.1:
List	GetBestSize: 100,80	Current: 300,100
Button	GetBestSize: 75,23	Current: 100,50

So GetBestSize() looks broken on OS 10.4 + wxPython 2.8.9.1 for multi-column lists. Setting the button height to 50 didn't work either.

You have to add it to the resource file by hand. For an example take a 
look at the simpleGrid sample shipped with PythonCard, where it is 
included in the resource file as;

"""
    { 'type':'Grid',
       'name':'mygrid',
       'position':(0, 0),
       'size':(400, 300),

"""

Hi,
The Grid component is mentioned in the PythonCard documentation for release
0.8.2 but is not presented as an option in the PythonCard Layout module.

Is there some way to include it?

Hmmm.....PythonCard deliberately sets the size to (-1,-1) in propertyEditor.py if the component's size matches the call to GetBestSize() - under OSX GetBestSize() is not staying constant for the multicolumn list and keeps matching the new size....hence size always gets set to (-1,-1).

You can get the same result under Windows XP, if you resize the component to exactly (50,50), which is GetBestSize()'s calculation of the minimum size. 

I'll do some more investigation to see whether this is an OSX bug in GetBestSize().

I get this too... OSX 10.4 + wxPython 2.8.9.1.

Did anybody come up with a fix for this....if not, I'll take a look next week....time permitting.

Anybody able to run the codeEditor with OSX 10.4+ and wxPython 2.8.9.0+....I still cannot get it to work in OSX due to the following error:

PyNoAppError: The wx.App object must be created first!

so it seems to be the same as 2.8.x.x. The other editors are fine, and as Glenn pointed out they all work on my XP box.

Fancy hacking your copy of the LayoutEditor? :-)

I've posted what I found on the developer list, but Kevin and I are on Tiger so any chance you could repeat the code changes I suggest here:

<http://article.gmane.org/gmane.comp.python.pythoncard.devel/256>

It's just two small code changes to layoutEditor.py. Failing that, I'll send my copy of the module.

Yes, that's the error I got. I'm attaching the stack trace.
I got effectively the same stack trace from running Resource Editor,

Well....it looks like the same nested device context limit that is causing the problem with the BitmapCanvas component is also causing the problem with the LayoutEditor. I don't see any error under Windows XP so I guess this limitation has been deliberately restricted to OSX.

Aaron....or anybody running 10.5 (I only have Tiger here, so I hope it's the same cause)....if you run the LayoutEditor from the command line or set the Python launcher to show all error messages in a terminal window, and then load the widgets example, when the window is only partly drawn do you see the stack trace ending with the error about "Cannot nest wxDCs on the same window"?

Also, is anybody seeing the same visible issue in the Resource Editor....where only a part of the window is showing? I just see it in the LayoutEditor but I get the stack trace in both.

I've been able to hack the editor code to stop this and get all of the components showing but I haven't tested it back on my Windows box to see if it breaks anything...and I can't understand why I'm not seeing the same visible issue in the ResourceEditor....just an error message.

Hi Neil,

No, I never worked it out. I run Windows XP under Parallels Desktop,  
so I just gave up and used the windows versions of LayoutEditor.
I'd love to see a solution if you can work it out!

Re: [Pythoncard-users] LayoutEditor trouble on Mac?

[XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]

6 months later...and I finally upgrade my trusty old G3 iMac to wxPython 2.8.9.1. Now I see these problems.

First there's the problem with the widget sample not fully loading in the resource editor. That seems to be the same issue as reported by Alex Schenkman in March ("BitmapCanvas problem in OSX") - it gets to drawing the BitmapCanvas widget and then fails due to "Cannot nest wxDCs on the same window". This appears to be due to changes in wxMac:

<http://lists.wxwidgets.org/pipermail/wx-users/2007-October/102956.html>

Having deliberately removed this component I then hit the other issue that 2.8.x.x users were seeing - not all of the window being displayed in the layout/resource editor. Did anybody work out what was causing this?
