You don't adjust the style of your frame directly, instead you only specify a type:

None

For no frame.

Button

For standard buttons with text in it.

ImageButton

For small buttons with images, e.g. the arrows of a scrollbar.

Text

For a text field, e.g. a status line display.

String

For a string gadget.

ReadList

For a read only list.

InputList

For a list that handles input (has a cursor).

Prop

For proportional gadgets.

Gauge

For gauge gadgets.

Group

For groups.

PopUp

For popup gadgets.

Virtual

For virtual groups.

Slider

For slider gadgets.

How the frame is going to look is adjustable via the preferences program.

Four spacing values belong to each frame that tell MUI how many pixels should be left free between the frame and its contents. These spacing values are also user adjustable as long as you don't override them with one of Area.InnerLeft, Area.InnerRight, Area.InnerTop, or Area.InnerBottom.

Note: The first object in a window may *not* have a frame. If you need this you will have to create a dummy group with just one child.
