Eclipse - Same .Java file in split view?
提问by Federer
Perhaps this is a trivial question, however it's something that is seriously annoying me. I'm editing someone's program at the minute and one of their .javafiles is absolutely massive. I'm trying to edit it at the moment, whilst referencing it as well.
也许这是一个微不足道的问题，但它让我非常恼火。我正在编辑某人的程序，他们的一个.java文件绝对是巨大的。我现在正在尝试编辑它，同时也引用它。
Is it possible to split the screen in Eclipse, to allow a split view of the same file?
是否可以在 Eclipse 中拆分屏幕，以允许同一文件的拆分视图？
回答by Alberto Zaccagni
A. Window -> New editor
A. 窗口 -> 新编辑器
or (slightly quicker)
或（稍微快一点）
B. Right-click on the tab with the code you want to see in another split view and choose "New Editor" to duplicate this tab in the sameeditor window (i.e. without having to open a completely new editor window as in A.)
B. 右键单击您想要在另一个拆分视图中查看代码的选项卡，然后选择“新建编辑器”以在同一编辑器窗口中复制此选项卡（即不必像 A 中那样打开一个全新的编辑器窗口。）
Then drag the new tab to the right until you see an arrow, then lift your finger. Doing it this way the two views will be in sync: everything you change on the left will change on the right.
然后向右拖动新选项卡，直到看到一个箭头，然后抬起手指。这样做，两个视图将同步：您在左侧更改的所有内容都会在右侧更改。

As commentedby mahesha999, there is a clone option in menu Window > Editor > Clonewhich opens separate cloned window/tab (instead of split view inside the same tab) that can be dragged to the 2nd monitor.
正如mahesha999所评论的，菜单中有一个克隆选项，可以打开单独的克隆窗口/选项卡（而不是同一选项卡内的拆分视图），可以将其拖动到第二个监视器。Window > Editor > Clone
