对于我的问题，我找到了很多不同的答案，但是似乎没人在为我工作。我正在尝试从Qt和Python设置GUI。 第一个问题是我必须使用：
from mainwindow import Ui_MainWindow
代替
from ui.mainwindow import Ui_MainWindow
因为似乎我无法从主文件夹读取到名为ui的子文件夹中。我只是绕过了它，将main.py移到ui文件夹中。 运行它的GUI，但指令self.setWindowTitle（“ ABC”）无效。
但是当我尝试不受欢迎的时候
self.ui.myOK.clicked.connect(self.onbc)
进入：
import sys
from qtpy import QtWidgets
from mainwindow import Ui_MainWindow
app = QtWidgets.QApplication(sys.argv)
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super().__init__(parent)
self.setWindowTitle("ABC")
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
#self.ui.myOK.clicked.connect(self.onbc)
def onbc(self):
print("abc")
window = MainWindow()
window.show()
sys.exit(app.exec_())
我获得：
Traceback (most recent call last):
File "/Users/alessandro/Documents/Lavoro/Phyton/sviluppo/gui/ui/main.py", line 21, in <module>
