用于 BoxLayout 的 PyQt 框架
PyQt Frame for BoxLayout
我现在已经被困了 2 个多小时，试图在我的 Boxlayout 周围放置一个 frame/border。

因为我显然不能在这里说出我想要的图片：
我想要 Displayvbox 周围的框架。 Displayvbox 包含一些标签和两个圆圈。怎么可能制作这个框架。我真的不明白这个....
QFrame 是一个容器小部件，它是一种仅用作“分组”其他小部件的方式的小部件。
如果你想在一个框架内显示小部件，你不能只将框架添加到布局 和将这些小部件添加到同一布局：你需要为框架，将小部件添加到 that 布局，然后将框架添加到“主”布局。
在您的情况下，您可以在 DisplayMainWindowBox 中创建框架并直接 return 而不是布局：
def DisplayMainWindowBox(self):
frame = QFrame()
frame.setFrameShape(QFrame.StyledPanel)
frame.setStyleSheet("background-color: blue")
frame.setLineWidth(3)
# directly install the layout on the frame
maingrahpic = QVBoxLayout(frame)
# which is the shorthand version of:
# maingrahpic = QVBoxLayout(frame)
# frame.setLayout(maingrahpic)
topgraphicbox = QFormLayout()
circle1 = circle()
topgraphicbox.addWidget(circle1)
BottomGraphicBox = QFormLayout()
circle2 = circle()
BottomGraphicBox.addWidget(circle2)
maingrahpic.addLayout(topgraphicbox)
maingrahpic.addLayout(BottomGraphicBox)
# return the frame, not the layout
return frame
def initMe(self):
# ...
maingraphicbox = self.DisplayMainWindowBox()
middlebox = QHBoxLayout()
middlebox.addLayout(llabelrow)
middlebox.addWidget(maingraphicbox)
middlebox.addLayout(rlabelrow)
# ...
我建议您阅读更多有关 layout management and also do some experimenting by using them in Qt designer 的内容，以便您更好地理解布局管理在 Qt 下的工作方式。
还要考虑 width() and height() 是所有 QWidget 类 的现有属性，因此您不应使用自定义变量覆盖它们，因为这样做会使访问这些属性更加困难。
最后，您的 circle 子类可能应该继承自 QWidget 而不是 QMainWindow（它通常用作顶级 window，而不是作为要添加到父级的自定义小部件).
