工具/版本

（1）安装环境：Windows7 64bit

（2）使用版本Python3.6

（3）PYQT5

（4）eric6

用到的图片

主要涉及的内容：

（1）tableWidget的使用

（2）QLineEdit的的的的的的的使用

（3）各个位置增加图标

（4）从登陆届面跳到主窗口

（5）TCP / IP通信

（6）访问数据库

一，登陆界面

1，界面设置图标和标题

self.resize(500, 300)  # 设置大小
        self.setWindowTitle("XX登录界面")  # 设置标题
        self.setFixedSize(self.width(), self.height())  # 禁止最大化
        icon = QtGui.QIcon()
        icon.addPixmap(QtGui.QPixmap("..\\Image\\10.jpg"), QtGui.QIcon.Normal, QtGui.QIcon.Off)
        self.setWindowIcon(icon)  # 设置窗口的图标

设置完成后，我们发现电脑任务栏的图标并没有修改，setWindowIcon这个函数起了一半的作用，学的Qt的的的的的都知道这个函数同时设置了程序的两个地方的图标显示，修改方法看参考如下链接

PyQt的的的的的任务栏图标问题

需要让窗户知道

import ctypes
ctypes.windll.shell32.SetCurrentProcessExplicitAppUserModelID("myappid")

2，按钮美化

参考这篇文章

Python的PyQt5-图形可视化界面（3） - 按钮--Qpushbutton

self.pushButton_2.setFlat(True)  # 设置按键边框取消

效果如下
