我要评论Python qt5-- 按钮点击事件
Python3.6 Ubuntu1604-pyQt使用（不使用Qtdesigner）基本组件—布局—按钮事件处理
PyQt5 +python3.6+qt designer弄个按钮事件
笔者想建立10个对象的随机排列，gui如的界面如下图所示，通过qt5 designer设计如下，保存为ui文件。
按钮点击事件
首先通过点击paixu按钮就可以在文本框中输出排序结果。
将qt5保存的ui文件通过vs code转换为Python文件

注意：需要在开头位置加入import sys，然后在对定义的setupUi函数的倒数第二行加入代码，按钮点击：self.pushButton.clicked.connect(MainWindow.hello)
新建文件.py
新建py文件调用上一个导出的文件的类，
# -*- coding: utf-8 -*-
from PyQt5 import QtWidgets
import sys
from random import shuffle
from Ui_suijipailie import Ui_MainWindow
class mywindow(QtWidgets.QMainWindow,Ui_MainWindow):
def __init__(self):
super(mywindow,self).__init__()
self.setupUi(self)
#定义槽函数
def hello(self):
list = ['li','wang','wen']
shuffle(list)
str1 = "排序为：" + '. '.join(list)
self.textEdit.setText(str1)
app = QtWidgets.QApplication(sys.argv)
#MainWindow = QMainWindow()
window = mywindow()
window.show()
sys.exit(app.exec_())
此时已经完成了按按钮实现三个对象【li，wang，wen】之间的随机排列并且输出结果。
