Detailed Description

This layout is not a general purpose layout, and should not be used as such.

Column layout shows items in columns. It shows only n last items pushed into it. Items can be pushed and popped like on stack, inserting an item before the end of the list is not supported, and, likewise, removing items except the last one is not supported.

To make that clear, pop and push functions are introduced. Trying to invoke one of the standard item manipulation functions from QGraphicsLayout will do nothing.

Since ColumnLayout needs the ability to hide certain items in it, it works only for QGraphicsWidget subclasses.
