PyQT更改内部QVBoxLayout在GridLayout中的位置

经过10-20次不同的尝试,以实现我想要的和本机QT文档调查,我终于找到了一个可能的解决方案。我不确定这是否是一种理想的方法,但它确实有效。如果你有更好的解决方案-请告诉我!我会被分配的。

这是解决办法

#  remove this item(it's  aLayout so we can't use removeWidget) from GridLayout
self.gridLayout.removeItem(self.buttonsLayer)

# now we can insert it into some new place. Voalia =)
self.gridLayout.addLayout(self.buttonsLayer, self.fieldGroupCounter + 1, 0, 1, 2)

希望它能帮助别人!谨致问候。

试试看:
