记一次pyqt5做登录窗口

首先要用designer设计ui界面

打开后就和c#一样拖动控件做ui界面

保存后是xxx.ui文件

再添加个工具

Arguments：-m PyQt5.uic.pyuic $FileName$ -o $FileNameWithoutExtension$.py

这个工具是把ui文件转换为py文件的
在ui文件右键选择新加的工具就会生成xxx.py了

生成py文件后，并不会运行
看下面代码主程序部分
你生成的py代码只是ui的部分

看一下逻辑部分
界面有两个按钮
那如何给按钮绑定事件

# 这一行是给pushButton_2按钮绑定事件
# 就是当点击pushButton_2时要触发的时间
self.pushButton_2.clicked.connect(self.send)

def send(self):
		# 获取comboBox里的内容
    user = self.comboBox.currentText()
    # 修改pushButton_2的内容
    self.pushButton_2.setText("发送中")
    # 弹出消息
    QMessageBox.information(MainWindow, user, "发送成功", QMessageBox.Ok)
