Re: [platform-swt-dev] Nonvisible widgets

[Manuel Nogales <mnogales@xxxxxxxxxxxxx>]

This is a snippet that shows it:

public class VerL {
	public static void main(String[] args) {
		Shell sShell = new Shell();
		sShell.setLayout(new FillLayout());
		sShell.setSize(new org.eclipse.swt.graphics.Point(430, 170));
		Composite composite = new Composite(sShell, SWT.NONE);
		composite.setLayout(new FillLayout());
		try {
			Class clasecarga = Thread
					.currentThread()
					.getContextClassLoader()
					.loadClass("CompositeWithFormLayout");
			Class[] classes = new Class[2];
			classes[0] = Composite.class;
			classes[1] = int.class;
			Constructor constr = clasecarga.getConstructor(classes);
			Object[] param = new Object[2];
			param[0] = composite;
			param[1] = new Integer(SWT.CENTER);
			constr.newInstance(param);
		} catch (Exception e) {
			e.printStackTrace();
		}
		Display display = sShell.getDisplay();

		sShell.setVisible(true);
		sShell.setFocus();
		while (!sShell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
		sShell.dispose();
	}
}

class CompositeWithFormLayout extends Composite {
	private Label label1 = null;
	private Label label2 = null;
	private Label label3 = null;
	private Text text1 = null;
	private Text text2 = null;
	private Text text3 = null;
	FormLayout layout = new FormLayout();
	FormData data;

	public CompositeWithFormLayout(Composite parent, int style) {
		super(parent, style);
		initialize();
	}

	private void initialize() {
		createComposite();
		this.setBackground(Display.getCurrent().getSystemColor(
				SWT.COLOR_INFO_BACKGROUND));

	}

	private void createComposite() {

		this.setLayout(layout);

		label1 = new Label(this, SWT.NONE);
		label1
				.setBounds(new org.eclipse.swt.graphics.Rectangle(
						47,
						20,
						94,
						13));
		label1.setText("Name");
		label2 = new Label(this, SWT.NONE);
		label2
				.setBounds(new org.eclipse.swt.graphics.Rectangle(
						48,
						44,
						95,
						13));
		label2.setText("User");
		label3 = new Label(this, SWT.NONE);
		label3
				.setBounds(new org.eclipse.swt.graphics.Rectangle(
						49,
						71,
						92,
						13));
		label3.setText("Password");
		text1 = new Text(this, SWT.BORDER);
		text1
				.setBounds(new org.eclipse.swt.graphics.Rectangle(
						168,
						16,
						156,
						19));
		text2 = new Text(this, SWT.BORDER);
		text2
				.setBounds(new org.eclipse.swt.graphics.Rectangle(
						168,
						42,
						154,
						19));
		text3 = new Text(this, SWT.BORDER);
		text3
				.setBounds(new org.eclipse.swt.graphics.Rectangle(
						167,
						67,
						154,
						19));

		data = new FormData();
		data.left = new FormAttachment(0, 20);
		data.right = new FormAttachment(30, 0);
		data.top = new FormAttachment(0, 20);
		label1.setLayoutData(data);

		data = new FormData();
		data.left = new FormAttachment(0, 20);
		data.right = new FormAttachment(30, 0);
		data.top = new FormAttachment(label1, 10);
		label2.setLayoutData(data);

		data = new FormData();
		data.left = new FormAttachment(0, 20);
		data.right = new FormAttachment(30, 0);
		data.top = new FormAttachment(label2, 10);
		label3.setLayoutData(data);

		data = new FormData();
		data.left = new FormAttachment(label1, 0);
		data.right = new FormAttachment(100, 0);
		data.top = new FormAttachment(0, 20);
		text1.setLayoutData(data);

		data = new FormData();
		data.left = new FormAttachment(label2, 0);
		data.right = new FormAttachment(100, 0);
		data.top = new FormAttachment(label1, 10);
		text2.setLayoutData(data);

		data = new FormData();
		data.left = new FormAttachment(label3, 0);
		data.right = new FormAttachment(100, 0);
		data.top = new FormAttachment(label2, 10);
		text3.setLayoutData(data);
	}
}
It seems to be that the problem is to load the composite with 
java.lang.reflect

thanks
