将 Qdockwidget 限制在一个象限而不是 Left/Right/Top/Bottom
Restrict a Qdockwidget to a quadrant rather than Left/Right/Top/Bottom
我有一个主 window 的三个主要部分，其中左侧（关键数据）应占据 window 的整个高度，而右侧的数据应分为顶部和底部。右下角的数据是相关的，但并不重要——这就是为什么我希望它是 un-dockable/closable.
Qt documentation 显示了一个用 C++ 编写的示例，但我不知道如何将其转换为 Python 代码，因为我没有 C++ 经验。
Qt Designer 应用程序将用户限制为 Left/Right/Top/Bottom，并且限制小部件的最大宽度不允许我占用未使用的 space（即不允许左侧的列表小部件占据主窗口的整个高度 window)
长话短说，要让 Qdockwidget 进入右下角，您必须在其上方放置另一个停靠小部件（它仍然限于 Right/Left/Top/Bottom DockWidgetArea）。看完下面 eyllanesc 的回答后，我将 post 两个解决方案。首先是他的代码的简化版本，然后是我最初 posted.
