如何通过Qt-designer创建的UI页面在python中应用面向对象的概念？
我使用Qt-designer创建了Dog and Cat的2个屏幕。它们非常相似，除了每页的图像显示狗或猫，而“狗”页上有1个额外的按钮。然后，我使用pyside2-uic将用户界面构建到python文件中。通过将UI对象添加到Dog或Cat的class参数中，我可以成功地分别运行每个对象。但是，这不是代码可重用。我想创建一个常见的“动物”对象，并根据其配置加载UI页面。
from PySide2 import QtWidgets, QtGui
from demo.ui import page1
class Dog(page1.Ui_MainWindow, QtWidgets.QMainWindow):
def __init__(self):
super(Dog, self).__init__()
self.setupUi(self)
self.button1.clicked.connect(self.func1)
self.button2.clicked.connect(self.func2)
self.buttonDogOnly.clicked.connect(self.dogOnly)
self.cancelButton.clicked.connect(self.cancelfunc)
def func1(self):
self.textEdit.append("This is button 1")
QtWidgets.QMessageBox.about(self, "popup", "BUTTON 1")
QtGui.qApp.processEvents()
self.update()
def func2(self):
self.textEdit.append("This is button 2")
QtWidgets.QMessageBox.about(self, "popup", "BUTTON 2")
QtGui.qApp.processEvents()
self.update()
def dogOnly(self):
self.textEdit.append("Dog only button")
QtWidgets.QMessageBox.about(self, "popup", "Dog only button")
QtGui.qApp.processEvents()
self.update()
def cancelfunc(self):
self.textEdit.append("This is CANCEL BUTTON")
QtWidgets.QMessageBox.about(self, "popup", "CANCEL BUTTON")
QtGui.qApp.processEvents()
self.update()
if __name__ == '__main__':
app = QtWidgets.QApplication()
homepage = Dog()
homepage.show()
app.exec_()
