演示代码：

复制代码 代码如下:

package swt_jface.demo9;

import org.eclipse.swt.SWT;

import org.eclipse.swt.layout.FillLayout;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.Group;

import org.eclipse.swt.widgets.Label;

import org.eclipse.swt.widgets.Shell;

public class GroupExamples {

}

display.dispose();

}

public static void main(String[] args) {

再看一个例子：

复制代码 代码如下:

package swt_jface.demo9;

import org.eclipse.swt.SWT;

import org.eclipse.swt.graphics.Image;

import org.eclipse.swt.layout.GridData;

import org.eclipse.swt.layout.GridLayout;

import org.eclipse.swt.widgets.Button;

import org.eclipse.swt.widgets.Combo;

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();

}

}
