再看一个例子：

复制代码 代码如下:

import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Group;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;
public class BugReport {

Display display = new Display();
Shell shell = new Shell(display);
public BugReport() {

shell.setLayout(new GridLayout(1, true));
shell.setImage(new Image(display, "C:/icons/bug.gif"));
shell.setText("Bug report page");

Group groupBug = new Group(shell, SWT.NULL);
groupBug.setText("Bug details");
groupBug.setLayout(new GridLayout(2, false));
groupBug.setLayoutData(new GridData(GridData.FILL_BOTH));

new Label(groupBug, SWT.NULL).setText("Priority");
Combo combo = new Combo(groupBug, SWT.BORDER);
combo.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));

new Label(groupBug, SWT.NULL).setText("Details");
Text text = new Text(groupBug, SWT.BORDER | SWT.MULTI);
text.setLayoutData(new GridData(GridData.FILL_BOTH));

Group groupProxy = new Group(shell, SWT.NULL);
groupProxy.setText("Connection setting");
groupProxy.setLayout(new GridLayout(2, false));
groupProxy.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));

new Label(groupProxy, SWT.NULL).setText("Proxy host");
Text textHost = new Text(groupProxy, SWT.SINGLE | SWT.BORDER);
textHost.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
new Label(groupProxy, SWT.NULL).setText("Proxy port");
Text textPort = new Text(groupProxy, SWT.SINGLE | SWT.BORDER);
textPort.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));

Button button = new Button(shell, SWT.PUSH);
button.setLayoutData(new GridData(GridData.HORIZONTAL_ALIGN_CENTER));
//button.setAlignment(SWT.CENTER);
button.setText("Submit bug report");
shell.pack();
shell.open();

while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}
public static void main(String[] args) {
new BugReport();
}
}
