1.使用 qt designer 设计出了个窗口，
pyuic编译的命令是把ui转成py文件：
pyuic5 -o test2.py test.ui
2.test2.py内容大致如下格式：
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'test.ui'
#
# Created by: PyQt5 UI code generator 5.11.3
#
# WARNING! All changes made in this file will be lost!
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(590, 490, 93, 28))
self.pushButton.setObjectName("pushButton")
self.textEdit = QtWidgets.QTextEdit(self.centralwidget)
self.textEdit.setGeometry(QtCore.QRect(120, 170, 221, 31))
self.textEdit.setObjectName("textEdit")
self.textEdit_2 = QtWidgets.QTextEdit(self.centralwidget)
self.textEdit_2.setGeometry(QtCore.QRect(380, 170, 301, 31))
self.textEdit_2.setObjectName("textEdit_2")
self.textEdit_3 = QtWidgets.QTextEdit(self.centralwidget)
self.textEdit_3.setGeometry(QtCore.QRect(120, 260, 571, 161))
self.textEdit_3.setObjectName("textEdit_3")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
self.menubar.setObjectName("menubar")
self.menuHeader = QtWidgets.QMenu(self.menubar)
self.menuHeader.setObjectName("menuHeader")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.menubar.addAction(self.menuHeader.menuAction())
self.retranslateUi(MainWindow)
self.pushButton.clicked.connect(lambda : print("点击了按钮"))
# self.pushButton.click()
QtCore.QMetaObject.connectSlotsByName(MainWindow)
MainWindow.setTabOrder(self.textEdit, self.textEdit_2)
MainWindow.setTabOrder(self.textEdit_2, self.textEdit_3)
MainWindow.setTabOrder(self.textEdit_3, self.pushButton)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "ok"))
self.textEdit.setWhatsThis(_translate("MainWindow", "<html><head/><body><p>dd</p></body></html>"))
self.menuHeader.setTitle(_translate("MainWindow", "header"))
3.再写一个类去继承 生成的类
import sys
from static.test2 import Ui_MainWindow
# from PyQt5.Qt import *
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtWidgets import QWidget
class Window(QMainWindow,Ui_MainWindow):
# i = 3
def __init__(self):
super().__init__()
print("初始化")
self.setupUi(self)
# print(self.i)
def setup_ui(self):
pass
def binding(self):
# self.textEdit.mouseDoubleClickEvent()
pass
4.然后就可以在 这个子类去绑定事件
运行
if __name__ == '__main__':
app = QApplication(sys.argv)
window = Window()
# ui = Ui_MainWindow()
# ui.setupUi(window) # 传入一个 window 对象
window.show()
sys.exit(app.exec_())
