Dear Adrian, current state of behaviour of dDateTextBox is unacceptable
for me.
Except issue with double click I put on Trac, lets try another:
- initial value of DataField is None
- so control Value is None too
- set focus on and clear value - set to empty string, and confirm with
Enter,
then you receive in log "Non-date value in txtEffectiveDate: '' is
type '<type 'unicode'>'"
- next, you will be unable to set proper date at all for that control,
you always receive error mentioned above, even if you write whole
date manually, e.g. "2010-01-01" - is invalid date too.
Although my proposal doesn't handle above issue,
it handles Null date - all empty strings are treated as Null dates
and are handled by backend correctly (until you set "NOT NULL" of course).
I tested this change.
Besides, I created wx.DatePickerCtrl based control that handles dates
even better.
When I finish to caress my code I'll publish it here.
