How would someone go about dynamically creating forms? Basically I'm
reading from a file which specfies the labels and entry widgets. Since
I don't know what labels are required I can just create the labels and
entry areas, I have to do it dynamically. I currently have:
class NamedEntry:
def __init__(self, master, text):
self.Frame = Frame(master)
self.Frame.pack(side='top', fill='x')
self.label = Label(self.Frame, anchor='w', width=15,
text=text)
self.label.pack(side='left')
self.entry = Entry(self.Frame)
self.entry.pack(side='left', expand=1, fill='x')
def get_value(self):
text = self.entry.get()
self.entry.delete('0', 'end')
return text
def set_value(self, value):
self.entry.delete('0', 'end')
self.entry.insert('end', value)
I have thought about putting the instance names in a list:
eg
L.append("instancename")
and then doing
for l in L:
l = NamedEntry(somewindow, somelabel)
but I can't use the get_value methods in the class because Python thinks
the instance name is just a string. Does anyone have any ideas on what
I could do or maybe another way od dynamically creating forms?
Any thoughts would be appreciated. Thanks.
