【问题描述】：
我在 QT Designer 中进行了应用程序设计，并将其保存为 .ui 文件。
接下来，使用此命令将.ui 文件转换为.py 文件 - pyuic5 -o design.py responsive_design.ui
在这之后，添加了这个？？？？？？
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
在文件的末尾使其工作。
但是，不幸的是，当我的 Python 文件启动时，应用程序以静态设计打开，不像预期的那样响应。
我看到了 -
这是 QT 的错误还是我的错误？有没有可能解决这个问题？
我的完整代码如下 -

【问题讨论】：
-
在放置元素之前使用一个盒子，然后在盒子中安装盒子或小部件，但不要在小部件内安装小部件
-
@SimoNSavioR 你是什么意思？请你发表一个答案好吗？
-
必须为顶级小部件设置主布局，而您创建了一个进一步的内部小部件（verticalLayoutWidget），它只是“浮动”在其中，因此它永远不会知道窗口何时调整大小和它不会自我适应。我建议您创建一个新的主窗口，首先拖动一个小部件，右键单击空白区域并从“布局”菜单中选择适当的布局。从那里，像以前一样在新窗口中恢复以前的布局，并覆盖以前的文件。阅读有关使用 layout managers in Designer 的更多信息。
