Automatically opening completion window in Eclipse

Question

我是Eclipse的新手，我想知道是否有可能在我键入（Visual Studio样式）时自动打开完成窗口，而不是单击Ctrl + Space ？

Answer 1

It is possible. You can simply write: .abcdefghijklmnopqrstuvwxyz in Auto activation triggers for Java field, under Preferences > Java > Editor > Content Assist .

While writing Java code, after the dot . the window opens automatically after a configurable amount of time (default is 200 ms.)

In general, what you can do is add an auto activation trigger, for example _ , so when you want the windows to popup, you type and delete that character (althought I don't think that's better than CTRL + SPACE ).
