问题描述：
想使用PyQt5 点击后弹出一个新窗口
思路：
0： 首先得绘制一个窗口
1： 一个点击按钮 【 初始化 —> 布局 —> 触发新窗口 】
2： 引入另外一个文件的窗口展示 【 这个窗口也可以单独运行 】
图片演示：
代码：
这个方法，指向新的文件 layout1
def layoutFn(self):
"""
想要有新的窗口， 引用其它已经写好的类
"""
import layout1 # 这个是可以单独运行的窗口
self.one = layout1.Layout1()
self.one.show()
layout1.py 这个文件也可以单独运行
import sys

from PyQt5.QtWidgets import QApplication ,QWidget ,QFormLayout , QLineEdit, QLabel
class Layout1(QWidget):

lineEdit3 = QLineEdit()
fromlayout.addRow(labl1, lineEdit1)
fromlayout.addRow(labl2, lineEdit2)
fromlayout.addRow(labl3, lineEdit3)
self.setLayout(fromlayout)
