Java實現按鍵精靈的示例代碼

@Override

}

//獲得鼠標位置
Point2D mp = robot.getMousePosition ();

//鼠標移動
robot.mouseMove (new Point2D (800,800));

     System.out.println (e.getSceneX ());
     System.out.println (e.getSceneY ());
});
//監聽鼠標鍵入
pane.setOnMousePressed (e->{});
//監聽鼠標釋放
pane.setOnMouseReleased (e->{});
//監聽鼠標在摁著某個鍵時的拖動
pane.setOnMouseDragged (e->{});
