卡布奇诺 - CPSplitView固定子视图的大小

Question

我有一个类GridNode继承CPSplitView用于包装GridELement类型的对象。 GridNode的每个连续分割将其分为两个新的GridNodes（包含GridElements，其父母调整大小）。

另一个级别 - GridToolbar继承自GridElement。它应该基本上具有与GridElement相同的行为，尽管大小不应该自动更改（因为容器已调整大小），而只能在用户拖动拆分器后才能更改。

问题是，即使我将AutoresizingMask设置为特定的方向（因为工具栏可以是垂直或水平的），它仍然会在两个方向上调整大小。

关于我能做些什么来防止这种情况发生？

我收到一个有用的建议here。创建我自己的委托，根据设置的固定值处理GridNode的子视图的自动调整大小，同时拖动分隔线是我必须做的。
