输出在屏幕截图中：问题是即使我在scrollArea下设置布局，Tab1也不会显示任何滚动条。 我期望滚动条的区域由红色矩形显示。

我记得这个类似的问题：-) 如何将水平滚动条关联到多个组框。
您仍然无法获得正确的滚动条的原因是，您在滚动区域内的窗口小部件没有最小高度，并且被允许缩小得足够远，以至于它们从不强迫滚动区域显示其滚动条。
在代码中，您可以通过以下方法解决此问题：
self.dockWidgetContents.setMinimumHeight(100)
虽然如此，但您不应对该从Qt Designer生成的文件进行任何直接编辑。 您应该做的是进入QtDesigner，选择小部件，然后在其属性列表的顶部为它们设置最小高度。
