You could place the ScrolledComposite inside a Composite before addign it to
the TabFolder.
Give the Composite a GridLayout and for the GridData of the
ScrolledComposite set the widthHint and heightHint to values you feel are
reasonable.
e.g.
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
TabFolder folder = new TabFolder(shell, SWT.NONE);
TabItem item = new TabItem(folder, SWT.NONE);
Composite c = new Composite(folder, SWT.NONE);
item.setControl(c);
GridLayout layout = new GridLayout(1, false);
layout.marginWidth = layout.marginHeight = 0;
c.setLayout(layout);
ScrolledComposite sc = new ScrolledComposite(c, SWT.H_SCROLL |
SWT.V_SCROLL);
GridData data = new GridData(SWT.FILL, SWT.FILL, true, true);
data.widthHint = 300;
data.heightHint = 400;
sc.setLayoutData(data);
Label l = new Label(sc, SWT.BORDER | SWT.CENTER);
l.setText("content");
l.setBackground(display.getSystemColor(SWT.COLOR_RED));
l.setSize(600, 800);
sc.setContent(l);
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
