Python使用QtSide6(PyQt)编写界面

1、安装QtSide6

开始菜单cmd

创建虚拟环境

复制代码

python -m venv env2

进入虚拟环境

复制代码

call env2/scripts/activate

安装Pyside6

复制代码

pip install Pyside6

2、设计Qt界面

打开designer.exe，设计界面

点击菜单【窗体】【View Python Code...】，点击【全部复制】按钮进行复制

3、使用Qt界面

打开PyCharm，新建工程，选择虚拟环境的python.exe

新建ui.py，将designer中的Python代码粘贴过去

python 复制代码

from PySide6.QtGui import (QBrush, QColor, QConicalGradient, QCursor,

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        if not Dialog.objectName():
            Dialog.setObjectName(u"Dialog")
        Dialog.resize(400, 300)
        self.pushButton = QPushButton(Dialog)
        self.pushButton.setObjectName(u"pushButton")
        self.pushButton.setGeometry(QRect(200, 220, 75, 24))

        self.lineEdit.setObjectName(u"lineEdit")
        self.lineEdit.setGeometry(QRect(130, 70, 113, 20))

        self.retranslateUi(Dialog)
        QMetaObject.connectSlotsByName(Dialog)
    # setupUi

    def retranslateUi(self, Dialog):

        self.pushButton.setText(QCoreApplication.translate("Dialog", u"\u70b9\u51fb", None))
    # retranslateUi

新建main.py

python 复制代码

from symtable import Class

from ui import Ui_Dialog
import sys
from PySide6.QtWidgets import QApplication, QMainWindow, QPushButton
from PySide6 import QtCore, QtGui

class Main(QMainWindow):
    def __init__(self):
        QMainWindow.__init__(self)

    def on_clicked2(self):
        auto_ui_window.lineEdit.setText("clicked2")
        print("Button click2")

def on_clicked1():
    auto_ui_window.lineEdit.setText("clicked1")
    print("button click")

if __name__ == "__main__":
    app = QApplication(sys.argv)
    main_window = Main()
    auto_ui_window = Ui_Dialog()
    auto_ui_window.setupUi(main_window)

    #事件处理方法1
    #auto_ui_window.pushButton.clicked.connect(on_clicked1)

    # 事件处理方法2
    QtCore.QObject.connect(auto_ui_window.pushButton, QtCore.SIGNAL("clicked()"), main_window,QtCore.SLOT('on_clicked2()'))

    main_window.show()
    app.exec()
    sys.exit(app.exec())
