Man, life is gooooooooooood....

By creating controls dynamically, my efficiency in
creating GUI code went up many many fold.  I must have
created 50 different panels in less than a day -
including code for designing, presentation, and
processing of user input.  I can not imagine how long
it would have taken me to do the same thing using the
static method.

Just for completeness, I am posting the final version
of my Control_Factory code, along with code for
destruction of controls on the fly.  May be this code
would be of use to other PythonCard users:

#!/usr/bin/python

"""
__version__ = "$Revision: 1.6 $"
__date__ = "$Date: 2004/05/05 16:53:27 $"
"""

import wx

from PythonCard import model

import new

from PythonCard import log
from PythonCard import model

class Minimal(model.Background):

	def addHandler(self, aMethod):
		# Add the Handler to our Handler list.
		if aMethod.name not in self._handlers:
			log.debug("addHandler: " + aMethod.name)
			#self._handlers[aMethod.name] =
event.Handler(aMethod)
			self._handlers[aMethod.name] = aMethod

	def delHandler(self, aMethod):
		# Add the Handler to our Handler list.
		if aMethod.name in self._handlers:
			log.debug("delHandler: " + aMethod.name)
			del self._handlers[aMethod.name]
			del aMethod
			
	def Control_factory(self, attribute, eventHandlers):
		name=attribute['name']
		methods=[]
		for eventName in eventHandlers.keys():
			eventFct=eventHandlers[eventName]
			def function(self, background, event):
				if eventFct==None:
					return None
				return eventFct(event)
			function.name = "on_%s_%s" % (name,eventName)
			method = new.instancemethod(function, self,
self.__class__)
			setattr(self, function.name, method)
			self.addHandler(method)
			methods.append(method)
		self.components[name] = attribute
		return methods
	
To use it, I simply set up a table like this:

				
({"type":"StaticText","name":"stFIELD1","text":"This
is easy:",'position':(5, 10), },{}),
					({"type":"TextField",
"name":"tfFIELD1",'position':(35, 10-4),
'size':(70,-1)},{}),
					({"type":"Button",
"name":"pbBUTTON",'label':'Execute', 'position':(70,
10+75)},
						{"mouseClick":self.on_pbBUTTON_mouseClick}),

and then invoke Control_factory repeatedly.

Thanks for a wonderful package PythonCard.  Couldn't
do this work without it.
