child_placement

This function returns information about placement of a child dock object inside another dock object.

The function returns true if child is effectively a child of this. placement should normally be initially setup to NONE. If it's set to some other value, this function will not touch the stored value if the specified placement is "compatible" with the actual placement of the child.

placement can be null, in which case the function simply tells if child is attached to this.

Parameters:

this	the dock object we are asking for child placement
child	the child of the this we want the placement for
placement	where to return the placement information

Returns:

true if child is a child of this.
