Hi guys,
I'm looking to completely hide a control. The setVisible stops the control
from displaying (a good start) but it still reserves the space in my
GridLayout for the control. Is there anyway I can stop this from happening
(I want to set the height of the control to 0 pixels).
Also is there anyway to clear the contents of a Composite control? I have a
class that extends Composite, but I want to be able to clear the contents of
it.
Thanks in advance,
Joe
