[Pythoncard-users] MultiColumnList questions

[Arthur E. <ar...@ia...>]

Hi,

some questions regarding the MultiColumnList. When I add items to the 
MultiColumnList, automatically I get a Heading. Is there a way to 
disable Headings all together? On OS X these headings take too much 
vertical space.

Another space related question, is it possible to narrow vertical 
space, so rows become much smaller? I tried changing the font size, but 
the row size doesn't change accordingly?

Thanks.

[Pythoncard-users] PythonCard suitability for a project; looking for opinions

[Brad A. <bra...@ma...>]

Hi. I've been spending the last few days taking a look at PythonCard, 
and I really like it. Kudos to Kevin, Dan, and the rest of you guys 
for your generosity in building such a nifty open-source tool and 
continuing to plug away at improving it. I'm a Python newbie of about 
six months, but I found PythonCard .8 to be very approachable.  It 
didn't take long to install and get the samples working. The tutorial 
walkthroughs were essential to helping me learn the basics, even 
though there were some bumps along the way (some small changes are 
needed to update the tutorials for .8, such as the reference to 
on_openBackground).

I was looking at PythonCard as a prospective GUI tool for a project 
at work. This project is a client-server-database application 
designed to replace an aging FileMaker solution with a MS SQL Server 
solution for the IT dept database. We need a full client app, not 
just a web interface, and it needs to be cross-platform so it can run 
the GUI on all the computers we manage. We also don't want to spend a 
million years building it, so a scripting approach makes sense rather 
than trying to do it in C++ or Java. So, that leaves us with choices 
like Runtime Revolution, RealBasic, Omnis Studio, etc. Or, we could 
go with open source tools like Perl, Python, Ruby, etc. For a variety 
of reasons, we really like Python the best among these choices, and a 
pure Python solution is likely to be a fairly practical and scalable 
approach as our app grows in complexity. We've used Python shell 
scripts in our environment to great success; it seems like a very 
approachable cross-platform language with many virtues.

The only trouble with Python is that it's not so easy to build GUIs. 
At least, not as easy as in proprietary platforms like RunRev, 
FileMaker, and RealBasic. We have a serious learning curve to climb 
on that front. At least, that's what I thought until I tried 
PythonCard. I've already been able to make a little headway 
prototyping the client app in PythonCard, though I have a long ways 
to go in really understanding the capabilities available in 
PythonCard. So, I have a number of questions, but before I dig in too 
much deeper, I'd like to get some opinions on a couple of basic 
questions.

Here is the first question: Am I crazy for considering PythonCard for 
use in a production environment? PythonCard is obviously not yet 
mature, and still has many gaps in the feature set, not to mention 
bugs. On the plus side, it seems to me that when users report bugs on 
this mailing list, they are generally identified quickly and fixed. 
It also seems to me that if we run into problems or gaps in the 
PythonCard feature set, we can fall back on the more mature wxPython, 
and so have a mix of wxPython and PythonCard in our GUI logic. Also, 
because PythonCard is open source, we can look under the hood figure 
out what's wrong if we need to.  Is this a fair assessment?

Second question: Do you see PythonCard as primarily a tool for 
building GUIs for small, simple apps, or do you think it will scale 
well to more complex apps, in terms of managing that complexity ? 
The app I'm imagining will require many windows, many dialog boxes, 
dynamically changing global menus, contextual menus, keyboard 
shortcuts (including function keys), and validation for data entry 
fields. It would also be nice but not required to have search results 
that populate as the user types, layouts changing within a given 
window, tab order between fields, drag & drop of files onto fields to 
populate paths, user-draggable icon objects, and tabbed interface in 
some windows.

I'd be grateful for any thoughts you can provide on this.

Thanks!

It could be done, but I'm not sure if it would be consistent since 
there is an explicit chdir done for the main background window, and 
child windows are just another window that just happen to have a 
parent. This could be problematic for the on_initialize handler in 
particular if it makes assumptions about the current working directory 
being the same as the module directory... Anyway, I can see pro and con 
arguments.

In the meantime, you can just make your own childWindow wrapper 
function that you call instead of the one in model.py. You can either 
provide the args as shown below or just use *args and *kwargs for the 
arg list.

def childWindow(parent, frameClass, filename=None, rsrc=None):
     cwd = os.getcwd()
     model.childWindow(parent, frameClass, filename, rsrc)
     os.chdir(cwd)

Also, in case you didn't know, self.application.applicationDirectory is 
the directory that contains your main source file in case you ever need 
to jump back there or make a relative path change.

[Pythoncard-users] PythonCard Changing directories

[bartek w. <ba...@re...>]

Hi, 

When I'm opening a child window, which is a pythonCard Alocated in different
directory, the PythonCard jumps to that directory. As my application involves a
lot of it, it becomes annoying to track "where am I". 

Is there any possibility of opening a child window without changing the current
directory ?.

EVT_CLOSE is bound to on_close, just remember to call event.skip() if 
you want to have the close event passed on, otherwise your app won't be 
killable except via the process manager, etc. The examples you were 
looking at should have been using on_close already. The background 
events are bound in model.py and include: activate, close, deactivate, 
idle, initialize, maximize, minimize, move, restore, and size. restore 
is the inverse of minimize.

[Pythoncard-users] Cleaning up when closing pythoncard applications

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

I just solved a problem I was having with a py2exe windows standalone
whereby the windows process never terminated after closing the app. As
you might suspect, this involved a thread in my app that didn't
terminate gracefully. I found in the PythonCard samples several examples
of using threads and in each case, the thread's daemon flag was set to 1
to make it daemonic so that it is cleaned up when the non-daemonic
thread (my Main GUI thread) exits. This solved my problem. However,
until I found this solution, I was trying another solution. Let's
pretend for a second that thread.setDaemon wouldn't work and we have to
make my secondary thread explicitly "killable" by having its run
function do:

def run(self):
	while self._running:
		# do stuff
		pass

and its stop func do:

def stop(self):
	self._running =3D False

so that my Pythoncard app can call this thread's stop function to
explicitly kill it. But where and when should this be called? I can
handle the reqests to close the app via a file menu exit callback, but
what about for "X"ing the application or other sorts of ungraceful
termination? I see that self.Close() gets called. I guess what I am
asking is what is EVT_CLOSE bound to? Where can I place cleanup
statements like thread stopping, etc?=20

Sorry about that. When I switched over to using the wx/lib/dialogs.py 
function wrappers for the system dialogs one of the changes was that 
the icon and button args got combined. The default style for the 
messageDialog is wx.OK | wx.CANCEL | wx.CENTRE, but if a style arg is 
supplied then that obviously isn't used. Consequently, where I was 
supplying an icon arg I forgot to add the button ids back in.

So as you figured out above, the on_componentDelete_command method 
should be changed to:

             result = dialog.messageDialog(self, msg, 'Delete Component',
                 wx.ICON_INFORMATION | wx.YES_NO | wx.NO_DEFAULT)

The on_menuEditCut_select method needs a similar fix:

             result = dialog.messageDialog(self, msg, 'Cut Component',
                 wx.ICON_INFORMATION | wx.YES_NO | wx.NO_DEFAULT)

I've checked these changes into cvs. I'll have to look at the other 
places messageDialog is used to make sure there aren't similar problems 
with the other tools or samples.

even funnier, on OS X, the delete function doesn't work at all. I do

Anyone else sees the same thing?

[Pythoncard-users] resourceEditor Delete command

[Daryl F. <fly...@sb...>]

Okay, here's something that a little funny...

You have spend five minutes or so tweaking a component in the
resourceEditor.  You aligned it perfectly, changed the text, labelled it
nicely, etc.  Then you accidentally hit the delete key.  Gah! The delete
confirmation dialog doesn't have a NO/CANCEL option! :)

Any change of changing line 1116 of resourceEditor.py to:
result = dialog.messageDialog(self, msg, 'Delete Component',
wx.ICON_INFORMATION | wx.YES_NO | wx.NO_DEFAULT)

It looks like the code is built to support this as it already checks for
result.accepted.

I am trying out this code editor component.  It looks something like this:

Could anyone point me to some documentation for this component?  I'm 
hoping there's a way to change the key words and make it work with SQL 
instead of python so the user can type SQL queries within the python 
application.  I'm also hoping it has code completion...

If CodeEditor wouldn't work easily for those needs, what would people 
recommend as the next fastest way of getting a little text area with 
word/code completion and syntax highlighting into a pyCard or wxPython app?

[Pythoncard-users] events added to grid component, simpleGrid updated as well

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

Alex added events to the grid component and the simpleGrid sample has  
been updated to use the PythonCard events.

I may end up tweaking the events some more before the next release, but  
I think that most of what you would use is covered. Even if you aren't  
running PythonCard from cvs, you should be able to just replace your  
local copy of grid.py and simpleGrid.py by downloading them from the  
web links below.

http://cvs.sourceforge.net/viewcvs.py/pythoncard/PythonCard/components/ 
grid.py

http://cvs.sourceforge.net/viewcvs.py/pythoncard/PythonCard/samples/ 
simpleGrid/simpleGrid.py

On a related note, the Grid, Tree, and MultiColumnList components all  
need simpler wrappers, assuming that is possible. At a minimum, the  
methods that you really need to make use of the components should have  
mixedCase aliases.

Re: [Pythoncard-users] Color in Lists

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

Thanks Daryl,
just as an FYI you don't have to use the Colour class, wxPython will 
accept a variety of formats and convert appropriately. You can use the 
same kind of representations you would in PythonCard.

COLOURS = ['black', '#660000', 'red',
            (255, 0x99, 0), (255, 255, 0), 'green',
            'blue', (0x99, 0xff, 0), '#cccccc', 'white']

is equivelant to

COLOURS = [Colour(0, 0, 0),       Colour(0x66, 0, 0),    Colour(0xff, 
0, 0),
            Colour(0xff, 0x99, 0), Colour(0xff, 0xff, 0), Colour(0, 
0xff, 0),
            Colour(0, 0, 0xff),    Colour(0x99, 0xff, 0), Colour(0xcc, 
0xcc,0xcc),
            Colour(0xff, 0xff, 0xff)]

All of the named colors that wxPython supports as well as their RGB 
values are defined in wx/lib/colourdb.py. The names are not 
case-sensitive.

RE: [Pythoncard-users] Color in Lists

[Daryl F. <fly...@sb...>]

Okay, here's my solution to this.  Please note, I'm sure that many other
people have better ways, but this works for me.

First, the List must become a MultiColumnList.  As a bonus, I was able to
remove my static text label and use the column label instead.  Then each
item is applied a wxCOLOR.  Below is a simple example.

Start up the resourceEditor.  For this example, build a new 'Standard
Template with File->Exit menu'.  Plop down a MultiColumnList and give it the
name 'MultiColumnList'.  Set it's size to be about 180 x 175.  Save the
file.  The .rsrc.py file should contain the following down near the bottom:
{'type':'MultiColumnList',
    'name':'MultiColumnList',
    'position':(15, 10),
    'size':(182, 169),
    'backgroundColor':(255, 255, 255),
    'columnHeadings':[],
    'font':{'faceName': 'Tahoma', 'family': 'sansSerif', 'size': 8},
    'items':[],
    'maxColumns':20,
    'rules':1,
    },

Now open up the .py file. and change it to:

from PythonCard import model
from wx import Colour

COLOURS = [Colour(0, 0, 0),       Colour(0x66, 0, 0),    Colour(0xff, 0, 0),
           Colour(0xff, 0x99, 0), Colour(0xff, 0xff, 0), Colour(0, 0xff, 0),
           Colour(0, 0, 0xff),    Colour(0x99, 0xff, 0), Colour(0xcc, 0xcc,
0xcc),
           Colour(0xff, 0xff, 0xff)]

class MyBackground(model.Background):
   def on_initialize(self, event):
      Items = "Bad Beer Rots Our Young Guts But Vodka Goes Well".split(" ")
      self.components.MultiColumnList.columnHeadings = "Color Code"
      self.components.MultiColumnList.items = Items

      for Item in range(len(self.components.MultiColumnList.items)):
         self.components.MultiColumnList.SetItemTextColour(Item,
COLOURS[Item])

if __name__ == '__main__':
   app = model.Application(MyBackground)
   app.MainLoop()

Here we build a list of colours called COLOURS.  Inside the on_initialize
method, the column is given a label and then populated with items.  Finally,
the for loop goes over each item and sets it's color.  Please note, this is
just a funny little example.  If you populate the list with more items than
we have colors Bad Things will happen.  I suppose you could do a max of
len(Items) and len(COLOURS) if you were worried about that...

Hope this helps,
-Daryl

[SNIP]

IIRC, I don't think it is supported in the underlying wx.ListBox
control used by the List component, but is supported by the wx.ListCtrl
which is underneath the MultiColumnList. You can check what the
wxWidgets docs say or find what you want to do in the wxPython demo and
then you'll have to call the appropriate wxPython methods to set the
colors.

Phil and I were finally able to get together to work on this problem.  
It appears that the problem is limited to GTK2. There isn't anything I  
can do about this, so the ball is in the wxWidgets court now. If you

That's  2295 pixels wide, so the text below wouldn't need to wrap to fit=20

[Pythoncard-users] TextArea - word wrap- how to?

[<gre...@co...>]

Hi,

I can't seem to get the word wrap to happen in a textarea.  It shows the 
portion of text that fits in the first row of the textarea but cuts off 
everything after that.  I've included the code I'm using at the end of 
this email (ignore my email's word-wrapping if possible)

Should I remove the existing '\r' s and '\n's from my text, could that 
be confusing the textarea?

Thanks,

Greg


This is the definition:
		widgetDefn={'type':'TextArea',
                                 'name':'txt'+ column[0],
                                 'position':(xPosWidget, yPos),
                                 'size':(255*9, NumRows*rowHeight),
                                 'alignment':'left',
                                 'border':'3d',
                                 'editable':False,
                                 'enabled':True,
                                 'text':'',
                                 'toolTip':'Values in this record field',
                                 'visible':True}
Here is where it is filled:
	 self.components[item].text=str(row[widgetCount])

And row[widgetCount] text is below:
'I saw a truck today.  There  was a man with a beard driving it.

IIRC, I don't think it is supported in the underlying wx.ListBox 
control used by the List component, but is supported by the wx.ListCtrl 
which is underneath the MultiColumnList. You can check what the 
wxWidgets docs say or find what you want to do in the wxPython demo and 
then you'll have to call the appropriate wxPython methods to set the 
colors.

[Pythoncard-users] Color in Lists

[Daryl F. <fly...@sb...>]

I've been playing with PythonCard for about a week now and I have to say I'm
impressed.  It seems very well thought out.

I do, however, have one issue.  I would like to set the text colour of
individual items in a list.  Right now I'm doing a whole lot of rework just
to get around having to do this, but it is becoming fairly difficult at this
point.  Is this even possible (without doing too much damage)?

[Pythoncard-users] VanPy Conference slides

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

The slides from the Vancouver Python Conference (VanPy) are now online. 
I did a presentation on PythonCard, so you can check out the PDF of the 
slides if you're interested. I don't think the slides are particularly 
interesting since the bulk of the presentation was building a mortgage 
calculator application in order to show off the various tools, creating 
a layout, going through some simple code, etc. However, the talk seemed 
well received, so I might end up doing it again and/or turning it into 
another walkthrough if I get properly motivated.

Good catch. I did a global replace on most of the files when I changed =20=

to mixedCase style PythonCard method names. In general, event.skip() is =20=

used everywhere for consistency, even though event.Skip() is still =20
valid since PythonCard is simply "decorating" the raw wxPython events =20=

with some helper attributes and providing method aliases.

But in the case of that sample, the events are bound manually and don't =20=

use the PythonCard event binding and dispatch, so the manually bound =20
events aren't decorated and the skip alias is missing. I went ahead =20
fixed the problem and checked the change into cvs.

Now that components are much simpler to create I plan to update the =20
Grid component so that all the events are bound just like the =20
MultiColumnList and Tree components. I'll update the sample and notify =20=

the list when that is done. For now, you can continue to do things like =20=

the sample.

Re: [Pythoncard-users] dbbrowser2 sample - catching events from wx widgets - grid +simple grid bug?

[<gre...@co...>]

Thanks for the advice, Alex, the simplegrid program is very helpful.

There may be a bug in the simplegrid program, is it better to report it 
here, or somehow get a sourceforge login deal and go that route?

The bug is in the file:
C:\Python23\Lib\site-packages\PythonCard\samples\simpleGrid\simpleGrid.py

The program does not work properly unless I do a global replace of 
event.skip() to event.Skip().  Just lower case s to upper case.  I'm not 
sure why that would be?

Here's the version info:

PythonCard version: 0.8
wxPython version: 2.5.2.7
Python version: 2.3.3 (#51, Dec 18 2003, 20:22:39) [MSC v.1200 32 bit

That's right - PythonCard doesn't (yet) have a grid widget, but this=20
example demonstrates the benefit of being able to "reach-through" to all=20
the wxPython widgets.

You should be able to get an idea of the events etc. for any widget from=20
the wxWindows documentation - in this case wxGrid.

Or - take a look at samples/simpleGrid - (included in the distribution, but=
=20
not available through the sample launcher), which shows how to bind and=20
handle each event type for a grid.

(Sorry - I haven't looked at it much myself yet, so I can't answer the=20
specific question).

[Pythoncard-users] dbbrowser2 sample - catching events from wx widgets - grid

[<gre...@co...>]

Thanks for the help on the dbBrowser sample.  I see how to create 
widgets at runtime now.  I just have one more question for today.

I am looking at the dbrowser2 sample now which on my computer is:
C:\Python23\Lib\site-packages\PythonCard\samples\dbBrowser\dbBrowser2.py
(note: there may be a bug in dbTable.py as I had to do a global replace 
of "wxPyGridTableBase" to "PyGridTableBase" before it would run.)

This program uses a grid to show a table.  But I don't believe that a 
grid is a pycard widget?  The author seems to be using 
wx.grid.PyGridTableBase.  My general questions are where can I find out 
what events can come from this grid and how do I bind actions to the 
events?  Specifically all I want to do is launch a new window when the 
user clicks on a row in the grid.

I'm not sure if my question is clear here, so let me know if you need 
any other details.

Thanks,

Greg

Creating components on the fly is easy, you just need to provide a =20
dictionary of the key:value pairs. Just look at the dictionaries for =20
each component in any .rsrc.py file and you'll see the same kind of =20
dictionary in use. For example, to create a button named 'btn1' in your =20=

code you might do something like:

self.components['btn1'] =3D {'type':'Button', 'name':'btn1', =20
'position':(0, 30), 'label':'btn1 hello'}

So, let's say you want to dynamically create 10 single-line fields when =20=

your application starts up. Here's one way you might do it:

     def on_initialize(self, event):
         insetFromEdge =3D 5
         padding =3D 4
         self.components['field0'] =3D {'type':'TextField', =20
'name':'field0', 'position':(5, 5), 'text':'field0'}
         height =3D self.components.field0.size[1]
         for i in range(1,10):
             name =3D 'field' + str(i)
             position =3D (insetFromEdge, insetFromEdge + i * (height + =20=

padding))
             text =3D name
             self.components[name] =3D {'type':'TextField', 'name':name, =
=20
'position':position, 'text':text}

I'm creating the first TextField outside the loop so that I can get the =20=

height of a TextField dynamically, which allows the code to work =20
regardless of the default text height on any given platform. You could =20=

just as easily, initialize the height to 0 and do an if block after the =20=

self.components[name] line to set the height.
