使用python进行简单的图形界面开发_python图形界面开发

1 处理的大体流程

2 使用PyQt5进行图形界面开发

2.1 入门参考链接

1）博客参考链接_01

2）博客参考链接_02

2.2 控件上添加执行动作

1）点击菜单栏上的“Edit Signal/Slot”按钮；

2）在要添加动作的控件上， 按住鼠标左键拖拽出如步骤2的图标；

3）放开鼠标左键， 弹出“Configure Connection”对话框；

4）根据步骤4， 选择控件的“激发动作的事件”；

5）根据步骤5，编辑一个函数名， 具体实现逻辑在python的调用代码实现；

6）根据步骤6， 选择要执行的函数；

7）点击“OK”确认动作；

2 调用QtDesigner生成的图形界面代码

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from functools import partial
from gu_test import * # 引入QtDesigner生成的模块
 
# 逻辑封装类
class MyWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MyWindow, self).__init__(parent)
        self.setupUi(self)
 
    # 按钮的处理逻辑：1 获取输入信息；2 处理输入信息；3 展示结果信息
    def convert(self):
        input_content = self.lineEdit.text()
        result = float(input_content) * 6.7
        self.textBrowser.setText(str(result))
 
# 主函数
if __name__ == '__main__':
    app = QApplication(sys.argv)
    myWin = MyWindow()
    myWin.show()
    sys.exit(app.exec_())
