Parent <--> Child and header files

[Mateusz 'vArDo' Bilinski <vardo fr pl>]

Hi, 
I've got problem in including header files when I want to do a parent-
child relation to be remembered from child widget. 

What I've got is CMainWindow class that consists of CMainToolbar and
CMainStatus. On a toolbar there's a button. When it will be hit I want
the text to show up on a status bar. So I want to remember a parent
widget pointer in Toolbar, to get back to CMainWindow class, and from
there push the text to statusbar. 

In other words I want to call:

'm_parent->status_bar.push("text")'

form one of the toolbars methods. I hope the idea isn't very bad. If
there a simple method I will be glad to know.

What is the PROBLEM is that I can't include "mainwindow.hh" file in
"maintoolbar.hh" files because I get errors (very strange;/ - listing at
the bottom). In "mainwindow.hh" I've got of course "#include
"maintoolbar.hh" because toolbar is the part of mainwindow.

At the end, here's the a part of gcc output when it comes to compile
maintoolbar.cc:

In CMainWindow I've got a class the inherits from DrawingArea if this to
help.

mainwindow.hh:46: error: syntax error before `;' token

is related to line:

RLC::CMainToolbar m_MainToolbar_Upper;


I hope hope I've discrabe clearly my problem.

Thanks for any suggestions in advance.
