簡介

   pyqt5是qt的Python版本，因為最近需要做一個有界面的程式，所以想到這個庫，這裡就稍微介紹它的安裝和使用教程

1.安裝qt5

可能需要安裝vs的c++編譯組件

pip install pyQt5

 2.使用拖拽組件編寫頁面

使用此工具打開組件

 ctrl+s 生成.ui文件

2.UI文件生成py文件

pyuic5 -o  a.py   a.ui

3.完整代碼

Main.py

# -*- coding: utf-8 -*-

import sys
from PyQt5 import QtCore, QtGui, QtWidgets
from a_ui import Ui_Dialog  # 假设您的UI类定义在a_ui.py文件中

class MyDialog(QtWidgets.QDialog):
    def __init__(self):
        super(MyDialog, self).__init__()
        self.ui = Ui_Dialog()
        self.ui.setupUi(self)

        # 连接按钮的点击信号到槽函数
        self.ui.pushButton.clicked.connect(self.on_pushButton_clicked)

    def on_pushButton_clicked(self):
        # 获取输入框的文本
        text = self.ui.lineEdit.text()
        print(f"输入的文本是: {text}")

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    dialog = MyDialog()
    dialog.show()
    sys.exit(app.exec_())
