Hi all,
I have an array of buttons that doesn't fit on a Composite. Instead I'm
trying to use a ScrolledComposite. Below is a simplified working
snippet. Could somebody please tell me why only one of the buttons in the
snippet shows up on the shell? The original was a custom Composite but the
effect seems to be the same on a stand alone app.
Thanks

import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.ScrolledComposite;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
public class Test {
public static void main(String[] Args)
{
Display disp = new Display();
Shell shell = new Shell(disp);
shell.setLayout(new FillLayout());
ScrolledComposite sc1 = new ScrolledComposite (shell, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
GridLayout gl = new GridLayout();
gl.numColumns = 4;
sc1.setLayout(gl);
Button button2 = new Button (sc1, SWT.PUSH);
button2.setText ("Button 1");
button2.setSize (400, 400);
sc1.setContent (button2);
Button button1 = new Button (sc1, SWT.PUSH);
button1.setText ("Button 1");
button1.setSize (400, 400);
sc1.setContent (button1);
sc1.layout();
shell.layout();
shell.open();
while(!shell.isDisposed())
if (!disp.readAndDispatch())
disp.sleep();
disp.dispose();
}
}

Thanks but that didn't work :( I've included a new snippet with the new
advice included. I just get an empty page. Removing the line
sc1.setContent (comp); gives me scrollbars but they have nothing in them.

Hi,
you have to call ScrolledComposite.setSize or ScrolledComposite.setMinSize.
Take a look at the API-documentation of ScrolledComposite. There you find an
example how to use ScrolledComposite (two methods of using).
Bye Stefan
