問題描述
我仍在為我的數(shù)據(jù)庫開發(fā) GUI，現(xiàn)在我遇到了另一個錯誤:
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'
我對 PyQt 一無所知，所以我不明白問題出在哪里.
I dont understand a thing about PyQt so i dont understand what the problem is.

推薦答案
Qt Designer 用于生成視圖的設(shè)計，pyuic5 將該設(shè)計轉(zhuǎn)換為python代碼，該元素必須與邏輯一起使用，另外建議不要修改它.
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.
第一個解決方案:
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_())
第二種解決方案:
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_())
第三種解決方案:
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_())
