[Pythoncard-users] Beginner question re dynamic menus

[Terry M. <ter...@gl...>]

Regards all, first time posting.

I've figured out how to add menu items easily enough using  
PythonCard's menu.py module's appendMenuItem method. But the  
corresponding deleteMenuItem is only a stub. I can almost get the  
underlying wx._core's.Menu's DeleteItem or RemoveItem to work, but  
not quite ... I can't seem to get the parameters right, and wxPython  
is still rather daunting at this point.

Any pointers to a faq, or a few lines of code if it's trivial, would  
be greatly appreciated.

Well, my brain's fried after a day of wxPython frames, panels, grids and 
  missing scrollbars. So I had to 'cheat' and run your code because I 
couldn't see anything.

Works OK, apart from the mysterious:

self.countValue = self.components.Gauge1.max + 1

which produces a Spinal Tap moment when you hit the stop button...was 
that intentional ;-)

That should (might) work, provided you include some important code 
within the loop (i.e. within "do stuff") - see below.

If you have enough info to 'do stuff' right away, you could simply put 
the loop at the end of your on_initialize() but it's likely that you 
need to let the user set things up before you are ready to 'do stuff', 
so you might need a button (e.g. 'Go') and put the loop within its handler.

The important thing is that you will be in a tight loop (i.e. everything 
will freeze) unless you allow a way for the  user interaction to happen. 
The easiest way to do that (see for example the Gravity sample) is to 
include something like

            # give the user a chance to click Stop
            wx.SafeYield(self, True)

within the loop.

Much too complicated - not just for beginners, but because it's too 
complicated :-) You only need threads if there is "real work" that could 
be time consuming needing to happen both in the background and the 
foreground parts. For simply setting a variable to stop a loop, there is 
no work, and no need for lengthy processing, in the UI event, so threads 
are very much overkill.


Something along the lines I suggested above, and the Gravity example,  
should work. If you are having trouble, and if it's not too long or 
complicated (or secret) include the whole of your code in the next email 
and we can be more specific. (or simplify 'do stuff' to be something 
simple like 'print going' and then send the whole code ....)

[Pythoncard-users] loop in body of main program

[James W. <ji...@cs...>]

I'm in Windows XP, and I'm trying to write something like this:


while going:
     do stuff


def on_startButton_mouseClick(...):
    going = 1

def on_stopButton_mouseClick(...):
     going = 0


My problem is where to put the loop. The best example I could find in 
the samples was the Gravity program. That program puts the loop in 
the startButton handler, and Gravity works fine on my machine.]When I 
do that in my program, it works  fine until I push the stop button. 
Then it freezes up and I have to kill it. I also tried putting the 
loop in an on_idle(...) method and got the same results.

I got around it finally using a timer and it's handler to replace the 
loop completely, but that's no good to me for two reasons:

2. it's too complicated for beginning students
1. the whole point was to expose them to loops

I think the RIGHT way to do this is to use a thread for the loop, but 
that's also too much for beginning students.


Any advice gratefully accepted.

[Pythoncard-users] BitmapCanvas problem in OSX

[Alex S. <al...@sc...>]

Hi:
This is my first post to the list, =)

When I add a BitmapCanvas in the resourceEditor I get lots of errors in the
console, and the component doesn't get added.
I'm running OSX 10.4.11, PythonCard 0.8.1 and who knows which wx under that.

Thanks in advance for any pointers.

Re: [Pythoncard-users] PythonCard on Mac

[Aaron S. <az...@bu...>]

I can report that Python and Leopard work great together. I have done  
plenty of work on it since January, and I'm pleased. Also wxWindows  
and PythonCard work well on Leopard.

The only area that I've been disappointed in the Mac-Python mix is  
with respect to database libraries. There's a fine one for MacPython  
library for MySQL, but to get to any other (Oracle, SQL Server  
especially) was a royal pain in the tuchus. I ended up writing a  
Python wrapper around JDBC, and then I have Python spark up a JVM and  
use the JDBC libraries to talk to the databases. And since some of my  
code runs on Linux, this worked well for that as well.

Re: [Pythoncard-users] PythonCard on Mac

[Aaron S. <az...@bu...>]

I just tried that, but it didn't seem to work for me. PythonLauncher  
started, ran for about 5 seconds, and then exited.
Perhaps a versions problem?

What I have that does work is a small shell script, run_RE.sh, like so:

#! /bin/sh
#
# A quick shell script to launch the PythonCard Resource Editor
#
python ./resourceEditor.py
#
#

And then I tagged all ".sh" files to be opened with Terminal. So now I  
can click the icon for run_RE.sh and it launches a Terminal window,  
and then Resource Editor on top of that. A bit cludgy, but it works.

Any other ideas out there?

I don't think so....I suspect a lot of people are having to deal with

[Pythoncard-users] PythonCard on Mac

[Aaron S. <az...@bu...>]

Hi guys,

I've been using/teaching PythonCard for a short while, and I've just  
moved to a Mac (no more blue screens, I hope). However, I'm still  
learning some of the best practices for Mac. Anyone using PythonCard  
on a Mac got some ideas/notes to share?

Specifically, I wasn't sure how you launch it. I put the package in / 
Users/azs/code/python/lib/PythonCard-0.8.2, with the tools located at / 
Users/azs/code/python/lib/PythonCard-0.8.2/tools. To run the editor,  
I'm just launching it at the command line using "python  
layoutEditor.py". Anyone doing differently?

Your advice appreciated!

Re: [Pythoncard-users] book / reading mat. recommendations

[John H. <ec...@ya...>]

Yes, using PythonCard can be addictive, isn't it? 
I've tried many many times to jump off it and go-on
with others but have always managed to find a way of
doing things without leaving some an elegant tool
package.

I just wish the open source Python community would
concentrate more on pushing PythonCard forward more -
than to keep creating yet another GUI of the day
package.

But then we are the one that have several Web Platform
packages with new ones keep appearing.  

BTW: sizer might not be a good reason for the need to
go native on wxPython because the level of wxPython
knowledge required is very shallow.  If you need to
encapsulate an unsupported control, or if you need to
tie your ap with Matplotlib, or things of that sort,
than you would need to go native.  

In my humble opinion, no matter how you slice it,
jumping from PythonCard to native wxPython is painful.

Re: [Pythoncard-users] Pythoncard-users Digest, Vol 20, Issue 1

[John H. <ec...@ya...>]

You can pass a None down.

As I said before, as long as you are not using more
advance form of doing things, you should be ok.

Be careful about calling events from on_initialize
because the components might not have been created
yet.

Re: [Pythoncard-users] Pythoncard-users Digest, Vol 20, Issue 1

[Tony C. <cap...@gm...>]

Where do you get the event object from, for an event that hasn't occurred?
These are automatically passed to the handler by pythoncard.
But, we cannot cal an event handler without passing an event object.

Re: [Pythoncard-users] actionBindings vs command vs userdata

[John H. <ec...@ya...>]

Well, as with any volunteer based software project,
the documentation is accurate at the time it was
written - so we all wish.  Pythoncard documentation
and tutorial is already much better than many of the
open-source projects I've seen.

I learned my PythonCard stuff through lots of tear and
sweats - from this mailing list, from reading the code
and examples (and to its credit - there are lots of
examples), experimenting, and sometimes get lucky by
stepping through the code using an interactive
debugger.

But I only know stuff I used.  If I see a question I
know the answer to, I always try to help.  Pythoncard
has helped me tremendously in the last years.  It's
the least I can do for it.

Re: [Pythoncard-users] How to programaticaly call an event handler (or force the event to occur programatically)

[John H. <ec...@ya...>]

If that's all you want to do, then it's simply.  Just
make a call to that event handler.

For instance:

   def on_button1_mouseClick(self, event):
      self.on_button2_mouseClick(event)

The only trap about doing this is that the event
structure is really that of button1 - not button2. 
So, if you are using code inside on_button2_mouseClick
such as:

   event.target.enabled=False

instead of say:

   self.components.button2.enabled=False

then you would be in trouble.  That's why simulating
an event by pushing an event into the event queue is
by far the safer way to do it.  Sorry but I have to
research this a bit to try to refresh my memory on how
to do it that way.  But for now, I think this should
work for you unless you're doing things more advanced.

Re: [Pythoncard-users] actionBindings vs command vs userdata

[Tony C. <cap...@gm...>]

Is this documented anywhere?
None of the tutorials I've read talk about this. In fact, they
completely leave out a lot of stuff regarding the
resource editor & layout editor capabilities.

I can't remember how to do that right off the top of
my head but I believe there is a way to stuff an event
into the event queue...

Re: [Pythoncard-users] How to programaticaly call an event handler (or force the event to occur programatically)

[Tony C. <cap...@gm...>]

I've got a combo box update event handler that is called when the user
makes a selection in the combo box.
When the event handler is called, other controls are updated accordingly.

However, this only occurs when the screen is visible, and the user
makes a selection.

During initialization, I want to select a default item in the combo
box, and I want the other controls to be updated accordingly, just as
if the user had made the selection. Sure, I can manually add code to
do this, but it seems like it's better to jsut use the built in event
handlers, and simulate a selection in the combo box, so I dont need to
duplicate the code which updates the other controls.

Does this explain the issue more clearly?

thanks

[John H. <ec...@ya...>]

I kind of get what you are trying to do but just to be
sure, can you elaborate a bit because I might be able
to answer it.  I do a lot of creating controls such as
buttons on the fly.

[Pythoncard-users] actionBindings vs command vs userdata

[Tony C. <cap...@gm...>]

Is there a description or tutorial that shows what these are for and
how to use them?

I want to "fake" the user having clicked on a combo box by manually
triggering the event, but I don't know how.
I'm wondering if I can take advantage of actionBindings or command to
fake the event being triggered.

When I click on an item in the combo box, I want other combo boxes to
be updated. I know how to do this.

But with the initial setting of the main combo box, I will initialize
and manually select the string from my code.
When this happens, I would like the select event handler to be called,
so I want to simulate that event.


Does anyone know how this can be done?

thanks

[Pythoncard-users] Using comboboxes

[Tony C. <cap...@gm...>]

I like the look/functionality of a combobox more than the list widget,
but I don't like the fact that the
text can be edited.
Is there a built-in way to make a combo-box non-editable?

[Pythoncard-users] How to programaticaly call an event handler (or force the event to occur programatically)

[Tony C. <cap...@gm...>]

I have a Radio Group with two buttons in it.
I can't call the event handler programmatically because event needs to
be passed.

When I tried setting one of the radio buttons programmatically, the
event handler never was called.

How can I force the event to be generated by setting one of the
buttons programmatically?

thanks
