Re: Parent <--> Child and header files

Hi :)

Didn't read your post completely (man, you've no idea how lazy iam :P),
but i figured you may need signals.
Check here:
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/apb.html

and/or read the recent discussion on the mailinglist about signals etc..

Hope this helps,

Bart

PS. i think you suffer from circular inclusion. Think about it, if A
includes B and B includes A, then A also includes A and A includes B and
B includes A... (*sound of bart going back to his beer* :P )
