我仍在为我的数据库开发 GUI,现在我遇到了另一个错误:
I am still working on the GUI for my Database and now i have a different error:
Traceback (most recent call last):
File "G:PythonDatabase Kast ThuisPyQt TestMainMenu_ui.py", line 84, in <module>
ex = Ui_MainWindow()
File "G:PythonDatabase Kast ThuisPyQt TestMainMenu_ui.py", line 16, in __init__
self.setupUi(self)
File "G:PythonDatabase Kast ThuisPyQt TestMainMenu_ui.py", line 55, in setupUi
MainWindow.setCentralWidget(self.centralwidget)
AttributeError: 'Ui_MainWindow' object has no attribute 'setCentralWidget'
我对 PyQt 一无所知,所以我不明白问题出在哪里.
I dont understand a thing about PyQt so i dont understand what the problem is.

Qt Designer 用于生成视图的设计,pyuic5 将该设计转换为python代码,该元素必须与逻辑一起使用,另外建议不要修改它.
Qt Designer serves to generate the design of the view, pyuic5 converts that design into python code, this element must be used with logic, in addition it is recommended not to modify it.
第一个解决方案:
import sys
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
ex = Ui_MainWindow()
w = QtWidgets.QMainWindow()
ex.setupUi(w)
w.show()
sys.exit(app.exec_())
第二种解决方案:
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent=parent)
ui = Ui_MainWindow()
ui.setupUi(self)
import sys
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())
第三种解决方案:
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent=parent)
self.setupUi(self)
import sys
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())
