python运行出来的界面与Qt designer预览的不一致
刚接触python，如题，python designer设计出的页面与用python 调用后显示的不一致，求问大神这个是什么问题，怎么解决。
#1. Qt designed预览界面
转化后的window.py文件见后文
2.python 运行main.py文件如图
3.main.py的代码
其中QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling)这一句注释掉也一个效果
# -*- coding: utf-8 -*-
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5 import QtCore
#导入designer工具生成的window模块
from window import Ui_Form
#定义一个主窗口类,继承了QMainWindow及Ui_Form
class MainWindow(QMainWindow, Ui_Form):
def __init__(self, parent = None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
if __name__ == '__main__':
QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling)
# 固定的，PyQt5程序都需要QApplication对象。sys.argv是命令行参数列表，确保程序可以双击运行
movieDownLoadApp = QApplication(sys.argv)
mainWindow = MainWindow()
mainWindow.show()
# 程序运行，sys.exit方法确保程序完整退出。
sys.exit(movieDownLoadApp.exec_())
4.window.py的文件是ui转过来的

你的主函数有点问题，可以这样写。
import sys
from PyQt5 import QtWidgets
import window
app = QtWidgets.QApplication(sys.argv)
window_Movie = QtWidgets.QWidget()
ui = window.Ui_Form()
ui.setupUi(window_Movie)
window_Movie.show()
sys.exit(app.exec())
```!
[运行结果是这样的](https://img-ask.csdn.net/upload/202008/18/1597739387_10930.png)
在你那个基础上也可以这样改，不知道对不对
# -*- coding: utf-8 -*-
import sys
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5 import QtCore
#导入designer工具生成的window模块
from window import Ui_Form
#定义一个主窗口类,继承了QMainWindow及Ui_Form
class MainWindow(QWidget, Ui_Form):
def __init__(self, parent = None):
super().__init__(parent)
self.setupUi(self)
if __name__ == '__main__':
QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling)
# 固定的，PyQt5程序都需要QApplication对象。sys.argv是命令行参数列表，确保程序可以双击运行
movieDownLoadApp = QApplication(sys.argv)
mainWindow = MainWindow()
mainWindow.show()
# 程序运行，sys.exit方法确保程序完整退出。
sys.exit(movieDownLoadApp.exec_())
change class MyApp(QtWidgets.QMainWindow, Ui_MainWindow): to class MyApp(QtWidgets.QWidget, Ui_MainWindow):
把代码发过来，我测试看看
在
Form.resize(690, 552)
开始，增加日志输出，看看是不是下面都被执行了，有没有出错。
解决了吗？
