Python QGraphicscene忽略网格布局的延伸
我有一个小部件,它分为两个子部件。一个显示图片,另一个提供编辑图片的选项。图片子部件所占的水平空间应该是编辑子部件的5倍。我在网格布局中指定此约束。但是,只要我将QGraphicscene(和视图)添加到编辑子小部件中,约束就会被忽略 我尝试了几种尺寸策略,但没有一种能满足我的需求,不过我使用这些策略的经验不太丰富Python QGraphicscene忽略网格布局的延伸,python,pyqt,pyqt5,qsizepolicy,Python,Pyqt,Pyqt5,Qsizepolicy,我有一个小部件,它分为两个子部件。一个显示图片,另一个提供编辑图片的选项。图片子部件所占的水平空间应该是编辑子部件的5倍。我在网格布局中指定此约束。但是,只要我将QGraphicscene(和视图)添加到编辑子小部件中,约束就会被忽略 我尝试了几种尺寸策略,但没有一种能满足我的需求,不过我使用这些策略的经验不太丰富 class MapWidget(QWidget): """ Widget that renders the map and displays properties """ d

两个小部件的比例不是5/6和1/6,而是相同的大小,这使得图片看起来很小,而编辑小部件太大。此外,一旦我删除了“group_blocks”小部件,edit子小部件就又有了合适的大小。因此,为了简单起见,我排除了它包含的所有其他小部件。尝试一下,并根据需要进行调整:

非常感谢,这是为我做的。有什么理由要依赖这种“黑客”吗?据我所知,您基本上将正确的组小部件放在不同的行中,以实现所需的布局。你知道为什么当你把它的父部件和左边的部件放在同一行时,QGraphicscene会这样做吗?
