我创建了一个带有菜单栏和4个可停靠小部件的
当我运行代码时，会显示如下内容。
我可以使用以下代码来调整第一个Qdockwidget中内容的大小。
上述代码是写在子窗口小部件的
注意，我的停靠窗口仍然不会根据子部件调整大小。停靠窗口会扩展和增加。有人可能会问，Qdockwidgets可以通过
我一直在寻找相关问题。

这些问题都没有解决我的问题。
我的代码启动可视化：
1- 当代码运行并显示在屏幕上时。
QMainWindow。第一个停靠窗口包含多个选项卡，第二个是QPainter widget，第三个是Matlabplot，第四个是pdf报告。当我运行代码时，会显示如下内容。
我想要变成以下这样。
每当屏幕运行时，我希望自动将屏幕分成四个小部件，并且我想要有选项卡来调整其大小以适应内容。
如果您有任何更好的小部件想法，欢迎提出。
代码更新
Qdockwidget的调整大小使得这篇文章变得更加重要。似乎Qt Qdockwidget调整大小一直是一个问题。我发现很难使用4个Qdockwidget编程我的Qmainwindow，其中dock会根据其内容（即子窗口）适合并调整大小。根据Qt文档，Qdockwidget会调整大小并考虑子窗口的大小。针对问题，我的主窗口有4个Qdockwidgets，我想让它们根据内容可调整大小。
到目前为止，我已尝试并使用以下大小函数。
self.sizeHint, self.minimumSize(), self.maximumSize() and self.setFixedSize(self.sizeHint()).
我可以使用以下代码来调整第一个Qdockwidget中内容的大小。
self.setFixedSize(self.sizeHint())
上述代码是写在子窗口小部件的
类widgets中的。
但这并不足以使其工作，还需要按照以下代码运行和生效。 self.first.setMinimumSize(self.first.sizeHint())
self.grid.setMinimumSize(self.grid.sizeHint())
self.third.setMinimumSize(self.third.sizeHint())
self.adjustSize()
self.first.setMinimumSize(self.first.minimumSizeHint())
self.grid.setMinimumSize(self.grid.minimumSizeHint())
self.third.setMinimumSize(self.third.minimumSizeHint())
注意，我的停靠窗口仍然不会根据子部件调整大小。停靠窗口会扩展和增加。有人可能会问，Qdockwidgets可以通过
resizeDocks()进行排列和控制。尝试使用此代码行，但仍无法获得所需的行为。我一直在寻找相关问题。

我的代码启动可视化：
1- 当代码运行并显示在屏幕上时。
2- 软件首次运行时期望的显示和要求。
3- 当用户在选项卡小部件之间切换时，希望调整大小以适应其内容，如下图所示。
4- 代码如下。
