JAVASwing GridBagLayout 布局

用GridBagLayout可实现复杂可控的布局。

以一个输入框为例：

final JTextField username = new JTextField(); final JTextField password = new JTextField(); JPanel regist = new JPanel(); regist.setLayout(new GridBagLayout()); regist.add(new JLabel("username:"), new GridBagConstraints(0,0,1,1, 0.0,0.0, GridBagConstraints.CENTER, GridBagConstraints.NONE, new Insets(2,2,2,2), 0,0)); &lt;pre name="code" name="code"> regist.add(username, new GridBagConstraints(1,0,1,1, 0.0,0.0, GridBagConstraints.CENTER, GridBagConstraints.NONE, new Insets(2,2,2,2), 200,0)); &lt;pre name="code" name="code">&lt;pre name="code" alt="JAVASwing GridBagLayout 格局"></p><p>后面输入框的长度可以修改值200 来改变。</p><p>具体GridBagConstraints 可参见GridBagConstraints</p><p>?</p> </p></div><div style="margin:0 auto;width:300px;height:250px;position:relative;"> <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <!-- 移动端全站正文 --> <ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-6147101717324856" data-ad-slot="1958144088" data-ad-format="auto"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script></div> <div class="subn-nav"><a href="//m.reader8.net">读书人网</a> ><a href="//m.reader8.net/jiaocheng/qtsjk/">其他数据库</a></div><div class="sp-jctu"><h3><span> 热点推荐 </span></h3><ul><li><p><a href="//m.reader8.net/jiaocheng/20140514/2329196.html">oracle数据库错误关闭之后恢复</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140512/2328908.html">Android手机客户端透过JSP实现与Tomca</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140511/2327943.html">数据库测试（3）</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140511/2327942.html">ORA-39212: 安装异常: 未正确加载 XSL</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140430/2318674.html">oracle 承停</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140429/2317737.html">Java应用之失去Oracle,Mysql数据库表信</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140429/2317736.html">关于JSP和struts绑定CHECKBOX保存数据</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140428/2316776.html">Shiro 与数据库交互的范例</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140428/2316775.html">EXP跟IMP示例</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140427/2315831.html">Cassandra Database(六)Multinode Clu</a></p></li> </ul></div><div style="display:none;"> <script> var _hmt = _hmt || []; (function() { var hm = document.createElement("script"); hm.src = "//hm.baidu.com/hm.js?d6151f323a57d16696165e47eee86d53"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(hm, s); })(); </script></div> <div class="footer"><p>触屏版 | <a href="//www.reader8.net/jiaocheng/20121118/1847682.html#fromapp">电脑版</a></p><p>读书人网 m.reader8.net</p></div> <script language="javascript"> function clickme(sad){ var divobjdiv = document.getElementById("divobjdiv" + sad); if(divobjdiv.style.display =="none"){ divobjdiv.style.display ="block"; }else{ divobjdiv.style.display ="none"; } var wenzi = document.getElementById('divobjimg' + sad); if(wenzi.innerText == "收起"){ wenzi.innerText = "查看更多"; }else{ wenzi.innerText = "收起"; } } </script> <div id="back-top"><a href="#top"><span></span></a></div> </body> </html>
