Use the width hint but also use FILL_HORIZONTAL. Grab says to expand the

but FILL tells it to ALSO size the control to that cell's width,
otherwise it will size the control only to the preferred size, which is
the width hint.

I've tried both of these suggestions, and ...
My problem is that I cannot get the "filling/grabbing" Text *AND* limit
the size of the dialog. I use WizardDialog.setPageSize(xsize, ysize) to
set the size I want. But along the way (WizardDialog.setWizard ->
updateSizeForWizard -> calculatePageSizeDelta) computeSize(SWT.DEFAULT,
SWT.DEFAULT, true) is called on the control for the WizardPage. Because
of the "SWT.DEFAULT", computeSize returns the size unrestricted by my
previous setPageSize, that is, it returns a size large enough to display
the entire string in the Text, that is, BIG.
I can debug and change the SWT.DEFAULTs in computeSize to xsize and ysize
and it works just fine. My gut says overriding methods in WizardDialog is
NOT the thing to do, but what else is there?

If you specify a widthHint for the GridData of the Text widget, this will be
used when computeSize(SWT.DEFAULT, SWT.DEFAULT) is called on the control
for the WizardPage.
public static void main (String [] args) {
String string = "Adding SWT Appeal to your Application\nSWT is a

the user-interface facilities of the operating systems on which it is

Display display = new Display ();
Shell shell = new Shell (display);
shell.setLayout(new FillLayout());
Composite parent = new Composite(shell, SWT.NONE);
parent.setLayout(new GridLayout(2, false));
Text t = new Text(parent, SWT.WRAP | SWT.BORDER);
t.setText(string);
GridData data = new GridData(SWT.FILL, SWT.TOP, true, false);
data.widthHint = 200;
t.setLayoutData(data);
Button b = new Button(parent, SWT.PUSH);
b.setText("Button 1");
b = new Button(parent, SWT.PUSH);
b.setText("Button 2");
b = new Button(parent, SWT.PUSH);
b.setText("Button 3");
b = new Button(parent, SWT.PUSH);
b.setText("Button 4");
shell.pack();
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
