/*
|
|
Implementation note: wxControlContainer is not a real mix-in but rather
|
|
a class meant to be agregated with (and not inherited from). Although
|
|
logically it should be a mix-in, doing it like this has no advantage from
|
|
the point of view of the existing code but does have some problems (we'd
|
|
need to play tricks with event handlers which may be difficult to do
|
|
safely). The price we pay for this simplicity is the ugly macros below.
