How to resize the components with the change in the size of the window?

Hello friends,
I am new to SWT . Can anyone help me as to how to resize the components in the window(Textboxes, labels, buttons) with the change in the size of the original window?? I mean the user can change the size of the window using mouse and accordingly i want to change the size of the components inside it . Can anyone please help me with a sample code??

try using

gridData = new GridData(GridData.HORIZONTAL_ALIGN_BEGINNING|
GridData.GRAB_HORIZONTAL|GridData.GRAB_VERTICAL);

The GRAB_HORIZONTAL and GRAB_VERTICAL properties should solve ur problem.
