Hi, I defined Text field and image contribution to toolbar as follows. I want it to be like a line with link in a browser. The text value may change, but it should have constant width, much larger than it is created now. text.setSize and composite.setSize doesn't help.
public class ContextField extends WorkbenchWindowControlContribution {
	protected Control createControl(Composite parent) {		      
		Composite composite = new Composite(parent, SWT.NULL);
        GridLayout layout = new GridLayout(3, false);
        Label labelImage = new Label(composite, SWT.RIGHT);
        labelImage.setLayoutData(new GridData(SWT.RIGHT, SWT.FILL, true, true));   
		text = new Text(composite, SWT.SINGLE | SWT.BORDER);
		text.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
		Point p = text.getSize();
		composite.setSize(320, p.y); // try 1 - doesn't help
		p = text.computeSize(SWT.DEFAULT, SWT.DEFAULT);
		System.out.println("text width=" + p.x + " height=" + p.y);
		p = composite.computeSize(SWT.DEFAULT, SWT.DEFAULT);
                composite.setSize(350, p.y); // try 2 - doesn't help
		System.out.println("Composite width=" + p.x + " height=" + p.y);
		return composite;		
	public boolean isDynamic() {
		return true;

Found the solution: the widthHint of GridData, here is the example:
text = new Text(composite, SWT.SINGLE | SWT.BORDER);
GridData data = new GridData(SWT.FILL, SWT.FILL, true, true);
data.widthHint = 350;

Best regards, Stella
