ComboViewer Horizontal Layout [message #1417368]

Hello,

i have a problem with a ComboViewer and the layout. The ComboViewer should be large as needed to show the hole content ? I don't want to set the width with the minSize, because the content length can change.

Example:

 import org.eclipse.jface.layout.GridDataFactory;
import org.eclipse.jface.viewers.ComboViewer;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;

public class ComboViewerSnippet {

    public static void main(String[] args) {

        // get display.
        Display display = new Display();
        Shell shell = new Shell(display);
        shell.setText("ComboViewerSnippet");
        shell.setSize(200, 200);
        shell.setLayout(new FillLayout(SWT.HORIZONTAL));

        Composite composite = new Composite(shell, SWT.NONE);
        composite.setLayout(new GridLayout(2, false));
        new Label(composite, SWT.NONE).setText("Test");

        ComboViewer viewer = new ComboViewer(composite);
        GridDataFactory.fillDefaults().grab(true, false).applyTo(viewer.getControl());
        viewer.add("Loooooooooooooooong Text");
        viewer.add("890ß Text");
        viewer.add("980ß Text");
        viewer.getCombo().select(0);

        new Label(shell, SWT.NONE).setText("New");
        shell.open();

        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
    }

}

Has anyone an idea?

Thanks

Hi,

To fix your problem, you must :

1. Replace GridDataFactory.fillDefaults().grab(true, false).applyTo(viewer.getControl()); by viewer.getCombo().setLayoutData(new GridData(GridData.FILL, GridData.BEGINNING, true, false));
2. Optionnaly : Replace shell.setLayout(new FillLayout(SWT.HORIZONTAL)); by shell.setLayout(new FillLayout(SWT.VERTICAL));

Regards,

Hussein
