PyQt4中的QTextBrowser超链接 [英] QTextBrowser Hyperlinks in PyQt4

问题描述

我有一个QTextBrowser，我输入了该示例文本：

I have a QTextBrowser where I've entered that sample text:

Column1    Column2
1 2 3 4    www.google.com

列之间有标签，数字之间有空格。 plainText = QTextBrowser.toPlainText（）给出：

Between the columns there are tabs and between the numbers there are spaces. plainText=QTextBrowser.toPlainText() gives:

Column1    Column2
1 2 3 4    www.google.com

现在，我想让链接可点击。通过这个，我将文本设置为html。
我写了一些字符串操作

Now, i want to make the link clickable. By this, I'll set the text as html. I wrote some string operations with

WORDS = re.split("(\W+)",plainText) 

这给出了

['Column1', '\t', 'Column2', '\n', '1', ' ', '2', ' ', '3', ' ', '4', '\t', 'www', '.', 'google', '.', 'com', ' ', '']

并用html格式的超链接替换www

and replaced "www" with the hyperlink in html-format

<a href=http://www.google.com>www.google.com</a>

然后，我删除了WORDS中的项目：。，test，。， com。

Then, I deleted the items in WORDS: ".", "test", ".", "com".

['Column1', '\t', 'Column2', '\n', '1', ' ', '2', ' ', '3', ' ', '4', '\t', '<a href=http://www.google.com>www.google.com</a>', ' ', '']

然后我重建所有的WORDS部分再次使用字符串，将换行符\ n替换为

Then I rebuild all the WORDS-parts again to a string, replacing the linebreak \n with

<br/>.

现在，当我将字符串设置为QTextBrowser时，链接显示正确且可点击。问题是：输入的文本，因为它现在是html，忽略/删除所有空格（如果不止一个）和标签！
输出看起来像（链接现在是蓝色并加下划线）

Now, when I set the string to the QTextBrowser, the link is displayed correctly and also clickable. Problem is: The entered text, as it is now html, ignores/removes all spaces (if more than one) and tabs! The output looks like (with the link now being blue and underlined)

Column1 Column2
1 2 3 4 www.google.com 

如何在不破坏格式的情况下制作超链接？

How can I just make a hyperlink without the formatting being destroyed?

也许我在错误的火车上？

Perhaps I am on the wrong train??

推荐答案

我想我明白了。如果它可能有用，这是我的解决方案：
一个html文件确实尊重你的格式，如果你把css中的样式设置为pre，而不是像QTextBrowser那样预先包装。
此外，最后可以直接用创建的超链接替换键入的链接。

I think I got it. In case it might be useful, here is my solution: A html file does respect your format, if you put the style in the css to "pre", and not like QTextBrowser to "pre-wrap". Moreover, in the end the typed links can directly be replaced by the created hyperlinks.

生成并设置到QTextBrowser的html文件然后partwise看起来喜欢：

The html file that is generated and setted to the QTextBrowser then partwise looks like:

<style type="text/css">#editor { white-space: pre; }</style>

<p id='editor', style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><a name="editor"></a>Column1        Column2</p>
