You can change a position or size of a member by interacting directly with the QTDrawable member itself but you must notify the group of any changes in the display characteristics of the QTDrawable by calling memberChanged(). <P> QTDrawable members can also be positioned within a GroupDrawable using alignment values. An alignment of 0 will place the member at the top and/or left position. An alignment value of 1 will place the member so that it's bottom and/or right is aligned with the bottom of the GroupDrawable's display space. <P> To reset the layer of an object you use the QTDrawable's Layerable object. QTDrawable objects do not contain any sense of layering, so the GroupDrawable uses the GroupMember objects to contain the information about a member's layer characteristics. <P><P><DL><DT><B>See Also:
