Thanks for the response.
What I noted so far:
The dDateTextBox does not have a user notification (like a Dabo dialog) when a
bad date is entered. I have attempted to do something about that by creating
a class that provides a dialog when the data entered is a bad date. But it
only works when the data in the dDateTextBox is "<None>". But the class does
not provide a warning dialog when the user is attempting to change a previous
entered good date with a bad date. The data is reverted to the original date
(IOW'S reverts the bad to the (original) good date).
Keeping with the principle that I should not change the framework I created a
new class. I even kept the old code (even thought I do not completely
understand it).
The theory is if the data is not a datetime - then warn the user and revert.
But it appears the actual data entered into the control is not present always
(at my class level). I've tried "self.Value" and "evt.EventObject.Value" and
they do not appear to return the actual data typed by the user. If the
control contained a valid date that date is returned (as the value) and not
the data the user entered. I have NOT determined what if anything has the
actual value.
If anyone has a suggestion I would appreciate the help.
class DateCheckDateTextBox(dabo.ui.dDateTextBox):
def afterInit(self):
self.super()
self.bindEvent(dEvents.LostFocus, self.__myonLostFocus)
def __myonLostFocus(self, evt):
if not isinstance(evt.EventObject.Value, datetime.date):
if isinstance(evt.EventObject.Value, basestring):
if evt.EventObject.Value == '<None>':
return
evt.EventObject.Value =
dates.getDateFromString(evt.EventObject.Value)
if not isinstance(evt.EventObject.Value, datetime.date):
#print 'in datetime check'
dabo.ui.dMessageBox.info(parent = self, message = 'Not a
valid date')
return
val = self.Value
try:
newVal = self.Value
if newVal != val:
self.Value = newVal
except ValueError:
pass
Thanks in advance,
Johnf
