Hello,
I have 2 composite in my UI. Left hand side is a button, while the right
hand side is a label.
My idea is when user click the button, the label in right hand side will
be disposed and create a Text. The problem is that when i click the button,
right hand side do not change UNTIL i minimize and maximize my application.

I was already call redraw() method, but do not success. Do anyone have any
idea?
Thanks for help~

Call layout() on the RH composite after the dispose/create.

redraw simply says repaint what's there. layout says to size and
position the children. Just creating a child doesn't size and position
it. It is at (0,0) with size (0,0). Layout will take the current layout
manager and size and position the children, including the new child.
