Re: [Vxl-users] vgui_DESTROY

[Karen M. <mc...@gm...>]

Hi, I looked in vgui/impl and a vgui_DESTROY event is dispatched when a
window is destroyed using GToK but not in the other implementations.  If yo=
u
are using MFC then there are no vgui_DESTRY events at all so it wouldn't
work.  You probably can fix this by adding something like:

  dispatch_to_tableau(vgui_DESTROY);

to the destructor ~vgui_mfc_adaptor() in vgui/impl/vgui_mfc_adaptor.cxx. If
you do fix this could you post the solution to the VXL mailing lists so it
can be fixed properly.  Thanks,
Karen McGaul
