Handle events happend in sub composites [message #461965]

Hi all,

I have a top level composite "A" which contains 2 sub-composites B and
C. I want A to response to button click and Keyup events happened in B
and C and do some validation of the data user put in B and C. I tried
to add A as a listener of B and C but it didn't work.... I was just
wondering what's the best way to do it. Thank you in advance.

Regards,
HS

btw, I am new to this stuff. so if it is not recommended to use sub
composites, please let me know. :)

public class CompA extends Composite
{
new CompB(this);
new CompC(this);

//Here I want to response to user event in CompB and CompC (text input,
check check box) and do some validation.
}

public class CompB extends Composite{}
public class CompC extends Composite{}

Cheers
HS
