[wxperl-users] weird Wx::DatePickerCtrl loading, where to find constant wxDefaultDateTime?

[Edward H. <ed...@do...>]

Hullo --

We've been using our own hand-rolled datepicker control, which pulls up 
a dialog with a Wx::Calendar on it.

Just the thing to replace with a Wx::DatePickerCtrl now that the real 
Wx::DatePickerCtrl is available!

So I've been trying to press Wx::DatePickerCtrl into service.  I've been 
having some problems.

First off, I can't 'use Wx::DatePickerCtrl' -- though if I 'use 
Wx::Calendar' I get  Wx::DatePickerCtrl loaded as a side effect.  This 
is pretty counterintuitive.

I also am not able to subclass it (use base 
qw(Wx::DatePickerCtrl))without doing a 'use Wx::Calendar' first to get 
Wx::DatePickerCtrl loaded, which also took me quite a while to figure out.

(Actually I just figured those two out while writing this message, while 
trying to put together a tiny app to demonstrate the problems I was 
having with it.)

The one problem I still haven't been able to figure out is how to import 
the constant wxDefaultDateTime so I can test whether the datepicker has 
a null date (having passed it the style DP_ALLOWNONE).  Where is that 
constant exported from?  How can I get to it?

sorry for this stream-of-consciousness-like email.  I've been wrestling 
with this stuff with a sleep deficit, which has probably made me a 
little stupider about it than I might have been.  If I've been unclear 
on anything let me know.

Versions involved:  wxPerl 0.57 on OS X. built with wxWidgets 2.6.3.

Any insight on the wxDateTime constant?

Thanks very much,
