我正在java swing中构建一个应用程序,我正在使用以下代码为UI提供本机操作系统外观

try {
  UIManager.setLookAndFeel(
    UIManager.getSystemLookAndFeelClassName());
  } catch (Exception e) {
    e.printStackTrace();
}

在OS X上,外观很好,但在Windows(XP和7)上,按钮看起来像这样.

我在其他项目上使用了这个完全相同的代码,它工作正常.但在这个特定的项目中,我得到了完全不同的外观.

我使用的是Java 1.6

提前致谢!

这段代码中〜0的含义是什么？
有人可以为我分析这段代码吗？

unsigned int Order(unsigned int maxPeriod = ~0) const
{
    Point r = *this;
    unsigned int n = 0;
    while( r.x_ != 0 && r.y_ != 0 )
    {
        ++n;
        r += *this;
        if ( n > maxPeriod ) break;
    }
    return n;
}

有什么方法可以阻止Chrome自动填充输入框？我有一个带有注册表单和登录表单的页面.在Chrome中,如果用户已经注册并且他们已到此页面登录,则注册表单上的密码输入框将填入其密码.我真的想强制注册字段永远不会自动完成.

我尝试过设置autocomplete ="false",但这没什么区别.

我正在开发一个wordpress插件,我需要一个可以上传图像的字段.由于wordpress有一个非常方便的上传器,如果我可以使用它会很棒.

有谁知道这是否可能？

谢谢

如果我使用自定义UITableViewCell,是否需要设置heightForRowAtIndexPath？在我的NIB中,我已经设置了单元格高度.

当我覆盖heightForRowAtIndexPath时,我的单元格的内容不会出现,即使它被设置为NIB中定义的高度.

如果我没有覆盖heightForRowAtIndexPath,则单元格的内容会出现,但由于默认高度不够大,因此存在溢出.

我很想知道更多关于什么触发了Safari中的Reader选项以及什么没有.我不打算实施任何会阻止它的东西,但作为一项技术练习很好奇.

以下是我到目前为止所学到的一些基本知识:

• 您至少需要一个H标签
• 它不是单独使用字符数,而是通过P标签的数量和长度
• 可能会寻找句子'.' 和其他标准

Safari will provide the 'Reader' if, with a H tag, and the following:

• 1 P tag, 2417 chars
• 4 P tags, 1527 chars
• 5 P tags, 1150 chars
• 6 P tags, 862 chars

If you subtract 1 character from any of the above, the 'Reader' option is not available.

I should note that the character count of the H tag plays a part but sadly did not realize this when I determined …

I was reading about regular expressions (I'm a regex newbie, but want to learn them) and came across this regex:

/^(?!http:\/\/www.google.com).*/

and I didn't know what or when it would match...so my question is just that, what/when would this regex match?

Thanks for helping out a regex padawan!

What is the best way to deallocate an array of array in javascript to make sure no memory leaks will happen?

var foo = new Array();
foo[0] = new Array();
foo[0][0] = 'bar0';
foo[0][1] = 'bar1';
foo[1] = new Array();
...

1. delete(foo)?
2. iterate through foo, delete(foo[index]) and delete(foo)?
3. 1 and 2 give me the same result?
4. none?

I am new to CppUnit. Is there any way to assert that a value must be less than zero? I am looking for something with similar behavior to CPPUNIT_ASSERT_EQUAL(). I was thinking there might be a test function named something like CPPUNIT_ASSERT_LESS_THAN().

As I'm writing JavaScript I'm always missing some fairly basic language features that JavaScript just don't have. So is there any library that would bring such features as trim, sprintf, str.endwith and etc. functions to JavaScript ?

I just have written those functions too many times and I'm also tired of copy/pasting them from my old code. It would be nice to have some library which has those implemented and tested in one place.

请注意,我不是在谈论像jQuery或Dojo等Ajax/DOM库.我知道那些库带来了我在这里谈论的一些功能,但不是全部.我想要一个独立于环境的库,以便相同的库可以与服务器端JavaScript一起使用.

到目前为止,我发现最好的库是php.js,但我不喜欢它如何污染全局命名空间.我也不太喜欢PHP函数的命名方式.
