DOCK Attribute

The DOCK attribute is restricted to a small set of gadgets only, and is principally aimed at the Frame gadget. It is quite difficult to use, but allows you to dock a frame to the left, right, top, or bottom edge of its container (frame or form) or to DOCK FILL, as in, dock to all to all edges simultaneously. The default is DOCK NONE.

When the frame's container resizes, the docked frame edges will remain 'stuck' to the corresponding container edges. Any docked edge is resized to be the same size as its container's edge.

View, Alpha, Paragraph, Textpane and Container gadgets support DOCK FILL only.

Note:
Currently, the DOCK attribute of the frame does not mix well with FoldUP frames.
