鼠标当前状态包括鼠标左/中/右键和单击/双击/抬起鼠标防抖(仅超出一定程度时才判断鼠标发生了移动)灵敏度可设置鼠标长按(在鼠标长按并且未发生移动时触发)时长可设置鼠标双击(两次点击的时间间隔足够小时判断为双击)时长可设置鼠标偏移量仅鼠标按下时有效可返回自点击时的总偏移量也可返回与上次鼠标事件之间的相对偏移量 补充 这个自制类在多键按下时会产生歧义也就是没法处理有如刁难一般的操作像是右键拖拽然后左键来添乱之类的。本来是想再重新写份代码以填补这个缺陷的但想想就有点怪什么场合下才需要满足这种怪异的操作。 自制类XJ_MouseStatus #XJ_MouseStatus.py from PyQt5.QtCore import pyqtSignal from PyQt5.QtCore import
