Under the Advanced Button,
you will be able to change your Button
Size, Button Type
and Menu Spacing.
Button Size can be
Fixed, or Variable.
Fixed means width of all
buttons will be set to the default value, all their
widths will be equal. Setting to Variable
means the width of each button will depend on how long
its caption text is.
There are three Button Types
to choose from, Flat, 3D
and Gradient, which allows
you to set how the buttons look like.
Menu Spacing allows you
to adjust spacing between buttons with a pixel value.
