The program I'm modifying uses something of a primitive way to check
the validity of values entered into widgets on a larger dialog. It uses
try-except after the user has pressed OK and departed from the dialog.
Isn't this supposed to be done in the apply method for the dialog? A typical data widget inside the set operations dialog class is: class OperationalSettingsDialog(tkSimpleDialog.Dialog): def __init__(self, parent, sdict): self.sdict = sdict tkSimpleDialog.Dialog.__init__(self, parent) def body(self,master): self.title("Operational Settings") ... # data widget Label( master, text="Max Hourly Event Rate: ").grid(row=5, sticky=W) self.rateVar = StringVar() Entry(master, width=10, textvariable=self.rateVar).grid(row=5, column=1) self.rateVar.set( "%s" % self.sdict["hourly_rate"] ) ... def apply(self): self.sdict["ok"] = True #END of class Furthermore, doesn't the use of tkSimpleDialog.Dialog provide an OK and Cancel button, which upon use causes the the invocation of the apply method to depart? --
