[litwindow-users] Using aggregate/accessors

[yrs90 <yr...@ya...>]

On accessing items:
I tried the following code.  Too bad, I can't create a debug build and use a
debugger.

wxListCtrl *pList = wxDynamicCast(event.GetEventObject(), wxListCtrl);
aggregate ag(make_aggregate(*pList));
accessor ac(ag["Items"]);

if (ac.is_valid() && ac.is_container())
{
	container c = ac.get_container();
	
	// yeah, it worked... etc.
}
else if(ac.is_valid() && ac.is_aggregate())
{
	wxMessageBox("is an aggregate");
}
else if(ac.is_valid())
{
	wxMessageBox("valid but not a container");
}
else
{
	wxMessageBox("not valid");
}

This code returns 'valid but not a container'.  Before I put the
is_container() check in, it generated a runtime error.

In a separate problem, I added a constructor/destructor to an otherwise
unchanged class that I pass to the framework and suddenly I started getting
runtime access violations.  Is there some type of change to the ADAPTER
declaration required when there is a constructor in the class?  I'll send
additional details if the answer solution isn't immediately apparent.

Best regards,
Joel
