问题一:今天更新我的Java版QQ,在网上找到了Substance外观包,效果不错,直接用了,可是设置水印问题时就出现问题,网上有现成的例子
- JFrame.setDefaultLookAndFeelDecorated(true);
- JDialog.setDefaultLookAndFeelDecorated(true);
- try {
- SubstanceImageWatermark watermark = new SubstanceImageWatermark(LoginFrame. class .getResourceAsStream( " /demo/001.jpg " ));
- watermark.setKind(ImageWatermarkKind.SCREEN_CENTER_SCALE);
- SubstanceSkin skin = new OfficeBlue2007Skin().withWatermark(watermark); //初始化有水印的皮肤
- UIManager.setLookAndFeel( new SubstanceOfficeBlue2007LookAndFeel());
- SubstanceLookAndFeel.setSkin(skin); //设置皮肤
-
- } catch (UnsupportedLookAndFeelException ex) {
- Logger.getLogger(LoginFrame. class .getName()).log(Level.SEVERE, null , ex);
- }

可是在我导入的包里死活包withWatermark方法不存在,于是就Google,最后看到一哥们说,自从subtance6.0以后就去掉了withWatermark设置水印方法,原因貌似是不安全,可是想用水印的效果呢?那你就换成substance5.0版本吧!换了之后果然能用了效果图:背景比较淡,水印不明显。
问题二:使用subtance出现异常UIDefaults.getUI() failed: 和org.jvnet.substance.api.UiThreadingViolationException,有一前辈说是包不能识别啥的,就我遇到的问题,只是换了皮肤之后框架布局变了,不在于能不能用的问题,关键还是在代码上,我遇到的这个问题就在于我的代码设置问题,先把我的部分代码贴出来分析一下:

这是一个类,时刻要记得UIManager设置前提,放在构造方法的最前面,调用时要用到Swing工作线程 SwingUtilities.invokeLater()来调用,我在LoginView中调用的方法:
- //userMainView = new UserMainView(oos, ois, v); // 加载用户信<br> SwingUtilities.invokeLater(new Runnable() {<br> public void run() {
- userMainView = new UserMainView(oos, ois, v); // 加载用户信息
- userMainView.setVisible(true);
- }
- });
- LoginView.this.setVisible(false);
- }
|
当你出现上述异常时是不是直接
- userMainView = new UserMainView(oos, ois, v);
- // 加载用户信息
- 没有少量一句,SwingUtilities.invokeLater(new Runnable()
- }
|
这是Swing工作形式,我的最后出来结果了,和以前系统默认的就是大小比例的不同,不再抛出异常,我认为是代码的问题,这是今天的收获写出来大家分享一下,希望对一些困惑的朋友。
有所帮助,我们这一行很多问题就要自己解决,太多的差异网上的东西只能是参考!Good luck,friends!
最后感谢Java.net的精英们制作出来这么漂亮的Swing外观来! GNU-UP UP!!!!!!
对你有所帮助就收藏一下,大家一起分享程序的快乐!
