寻找一个高效的基于 Java Swing 的控制台
我正在寻找一个高效的 Swing Java 组件，我可以将其插入到我的应用程序 UI 中.我已经尝试在 Swing 中使用 JTextArea 等类，但无济于事；它们根本不够高性能，并且有任何严重的缺点.此外，如果它具有标准的控制台功能，例如滚动锁定、清晰的控制台、颜色等，那就太好了.
I'm looking for a highly efficient Swing Java component which I can just plug into my application UI. I already tried using the classes within Swing such as JTextArea with no avail; they simply aren't high-performance enough and have any crippling drawbacks. Additionally, it'd be nice if it had standard console features such as scroll-lock, clear console, colours, and so on.
忘了说，这个控制台会有很多调试信息流入，它需要完全可滚动.
Forgot to say, this console will have a lot of debug information streaming into it, and it needs to be fully scrollable.
干杯，

推荐答案
我看不出使用 JTextPane 有什么问题.它支持您可以在将每段文本添加到控制台时指定的属性.清除它显然也很容易.添加到滚动窗格时，它还支持滚动.
I fail to see what is wrong with using a JTextPane. It supports attributes which you can specify as each piece of text is added to the console. Clearing it is also obviously a no brainer. When added to a scroll pane it also supports scrolling.
您可以使用 智能滚动添加滚动锁定.
You can add scroll locking by using Smart Scrolling.
另外，它会过早删除文本并且
Plus, it removes text too early and
不知道这意味着什么，因为除非您专门从文档中删除文本，否则永远不会删除文本.
No idea what that means as text is never removed unless you specifically remove it from the document.
不允许用户滚动正在输入输入(afaik).这效果是你只看到文字行数同时闪烁保持不变.
doesn't allow the user to scroll while input is being entered (afaik). The effect is that you just see text flashing while the number of rows remains the same.
默认情况下，假定代码在 EDT 上执行，文本会在文本附加到文档时自动滚动.这种滚动可以通过上面链接中提供的示例来控制.
By default the text scrolls automatically as text is append to the document assuming the code is executed on the EDT. This scrolling can be controlled the the example provided in the link above.
但我仍然想要图书馆解决方案
but I'd still like a library solution
我不知道
自动着色文本来自不同的流
auto-colourise text coming from different streams
消息控制台可能会给您一些想法.
(即，检测 [error] 前缀线)和着色线基于这个)
(i.e., detect [error] prefix on a line) and colourise lines based on this)
这很容易通过将 DocumentFilter 添加到文本窗格的 Document 来完成.您可以在将文本插入文档时添加属性.
This is easily done by adding a DocumentFilter to the Document of the text pane. You can add attributes as text is inserted into the Document.
