卡布奇诺 - CPSplitView固定子视图的大小

Question

我有一个继承自GridNode的类CPSplitView，用于包装GridELement类型的对象。 GridNode的每次连续拆分将其分为两个新的GridNodes（包含GridElements，并与其父级调整大小。）

另一个类 - GridToolbar继承自GridElement。它应该基本上与GridElement具有相同的行为，尽管大小不应自动更改（因为容器已调整大小），但仅在用户拖动拆分器之后。

问题是，即使我将AutoresizingMask设置为特定方向（因为工具栏可以是垂直或水平），它仍会在两个方面都调整大小。

有什么建议可以防止这种情况发生吗？

我收到了一个有用的建议here。在拖动分隔符的同时创建我自己的委托来处理根据固定值集自动调整GridNode子视图的大小是我必须做的。
