Intelligent Resizing

So far, you have considered the static layout of the form, but often the forms need to be resized by you at run-time.

Most gadgets have an ANCHOR attribute and a few support the DOCK attribute. These allow you to define intelligent position and resize behaviour when the gadget's container resizes, which allows you to have more than one resizable gadget on the same form.

Note:

The ANCHOR and DOCK attributes are mutually exclusive. Setting the DOCK attribute resets the ANCHOR to the default; setting the ANCHOR attribute resets DOCK to none.

You can set these attributes only when you define the gadget; you are not allowed to change the resize behaviour at run-time.

Note:

VIEW and ALPHA gadgets should always be placed in their own frame, with no other gadgets. Use the frame's DOCK or ANCHOR attributes to get the behaviour wanted.
