Hello Shwetha,

Quote:

still not clear.

I get the following error :

cannot call member function 'virtual bool Upp::TopWindow::Key(Upp::dword, int)' without object

Koldo has shown the correct generic way: If your derived class is based on TopWindow, it will work. But in your specific example, the button is called froım Tab5_Dynamic class, which is derived from ScatterDemo. So you should call ScatterDemo::Key (or any other base class that derives from Upp::Ctrl, thati s suitable), if you need to further process ScatterDemo keys (you'll probably need that in the future.)

Try this instead:

bool Tab5_Dynamic::Key(dword key, int val)

{
	LOG("key");
	DUMP("KeyAction");
	
  if(key == K_CTRL_S) {
        bStart.Action();
        return true;
    } else
        return ScatterDemo::Key(key, val); 
}

Best regards,
