问题描述
如何检查当前是否按下了任何鼠标按钮，如果按下，是哪个按钮?
How can I check if currently any mouse button is pressed and if so, which one it is?
问题是我需要在MouseListener.mouseEntered() 中使用这种信息.我检查了 MouseEvent 但我找不到对我有帮助的方法.
The thing is that I need to use this kind of information in MouseListener.mouseEntered(). I checked MouseEvent but I could not find the method which would help me.
getButton() 方法似乎只有在按钮状态发生变化时才返回值.
The getButton() method seems to only return value if there has been change in buttons' state.
有没有办法在不手动跟踪这个情况下通过 MouseListener.mousePressed()/mouseReleased() 方法找到这个.
Is there a way to find this out without manually keeping track of this somehow vie MouseListener.mousePressed()/mouseReleased() methods.
推荐答案
大概您想根据按下的按钮调用特定代码，以便您可以执行以下操作:
Presumably you want to invoke specific code depending on the button pressed so you can do something like:
if (SwingUtilities.isLeftMouseButton(...))
// do something
