/*
|

Implementation note: wxControlContainer is not a real mix-in but rather
|
||||
a class meant to be aggregated 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.
|
||||
This header declares wxControlContainer class however it's not a real
|
||||
container of controls but rather just a helper used to implement TAB
|
||||
navigation among the window children. You should rarely need to use it
|
||||
directly, derive from the documented public wxNavigationEnabled<> class to
|
||||
implement TAB navigation in a custom composite window.
