Re: [Pythoncard-users] Creating dynamic window

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

There are people at the Python newsgroup suggesting
that I should avoid using exec to accomplish this. 
Here's what they suggested:

#!/usr/bin/python

"""
__version__ = "$Revision: 1.6 $"
__date__ = "$Date: 2004/08/17 19:46:06 $"
"""

import new

from PythonCard import model

rsrc = {'application':{'type':'Application',
          'name':'Minimal',
    'backgrounds': [
    {'type':'Background',
          'name':'bgMin',
          'title':'Minimal PythonCard Application',
          'size':(200, 300),
         'components': [

] # end components
} # end background
] # end backgrounds
} }

def mouseclick_factory(parent, name):
    id_num=int(name[-1:])
    parent.components[name] = {'type':'Button',
                                 'name':name,
                                 'label':name,
                                 'position':(5,
5+id_num*30),
                                 'text':name}
    def function(self, event):
        print "You clicked '%s'." % name
    function.name = "on_%s_mouseClick" % name
    return function

class Minimal(model.Background):
    def on_initialize(self, event):
        self.components['field1'] =
{'type':'TextField','name':'field1','position':(5,
5),'size':(150, -1),'text':'Hello PythonCard'}
        name = "Button1"
        function = mouseclick_factory(self, name) # as
before
        method = new.instancemethod(function, self,
self.__class__)
        setattr(self, function.name, method)

if __name__ == '__main__':
    app = model.Application(Minimal, None, rsrc)
    app.MainLoop()

Unfortunately, it doesn't work.  PythonCard doesn't
calll the fuction created by the mouseclick_factory. 
However, if I place the following statement right
after the setattr call, it works (proving that the
function actually gets created).

        self.on_Button1_mouseClick(event)

Any idea why this doesn't work?

Thanks,
