SWT跨平台输入检测 [英] SWT Cross-Platform Enter Detection

问题描述

我在SWT中有一个全局过滤器(Display.addFilter)，我想在其中检测 Enter 键.在Windows中，按Enter会在KeyListener事件的'keyCode'部分生成SWT.CR.这个假设对所有平台都安全吗，还是应该检查

I have a global filter (Display.addFilter) in SWT in which I want to detect Enter key. In Windows, pressing Enter generates SWT.CR in 'keyCode' part of KeyListener event. Is this assumption safe for all platforms, or should I check if

keyCode == SWT.CR || keyCode == SWT.LF?

谢谢.

推荐答案

如果您想在小部件聚焦时用户按下Enter键来捕获事件，请使用TraverseListener或类型为.然后，您检查

If you want to catch the event when the user presses the Enter key while a widget is in focus, use a TraverseListener or a Listener with type SWT.Traverse. Then, you check

if (event.detail == SWT.TRAVERSE_RETURN) {
    // The user pressed Enter 
}
