+# 简单的窗口贴边隐藏
+
+## 大概思路
+ - 1.思路是当窗口进入左边，顶部，右边一半时，此时判断窗口的坐标
+ - 2.如果窗口的x坐标小于0 则需要隐藏到左边
+ - 3.如果窗口的y坐标小于0 则需要隐藏到顶部
+ - 4.如果窗口的x坐标大于屏幕宽度-窗口宽度/2 则需要隐藏到右边
+
+## 事件
+ - 1.mousePressEvent，鼠标按下事件，主要记录按下的坐标
+ - 1.mouseMoveEvent，鼠标移动事件，用于移动窗口
+ - 1.mouseReleaseEvent，鼠标弹起事件，用于判断是否需要隐藏窗口
+ - 1.enterEvent，鼠标进入事件，用于窗口隐藏后，是否需要暂时显示预览
+ - 1.leaveEvent，鼠标离开事件，用于窗口暂时显示后自动隐藏效果
