[Qt-interest] qtoolbar

[phil prentice]

HI Pradeep 

  Sorry for the delay in getting back to you.
  And thankyou for your example.  I am using Qt version 4.2.1 and yes your 
example does work for me.  I will update your example to follow what my code 
does in my app and see if I can understand why my app does not work in the 
same way.

  I will let you know how I get on.

Thanks again

Phil Prentice
