出于某种原因，我可以运行此代码，但我无法在文本区域中粘贴文本。有什么想法吗？

就像我说的那样，当它运行时无法右键单击，它全部被禁用，我无法粘贴我所支持的文本。有关为什么会发生这种情况的任何想法？
答案 0 :(得分：0)
进行此导入：
import java.awt.event.MouseEvent;
然后......
private void textfiledMousePressed(java.awt.event.MouseEvent evt) {
if (evt.getModifiers() == MouseEvent.BUTTON3_MASK){
System.out.println("Hey I'm using right click!");
}
}
