In a dialog box, one button may be designated the
“default”
button (meaning, roughly,
“the one that gets invoked when the user presses <Enter>”).
active indicates that this is currently the default button;
normal means that it may become the default button, and
disabled means that it is not defaultable.
The default is normal.
Depending on the theme, the default button may be displayed with an extra highlight ring, or with a different border color.

- Database Class: Width
- If greater than zero, specifies how much space, in character widths, to allocate for the text label. If less than zero, specifies a minimum width. If zero or unspecified, the natural width of the text label is used. Note that some themes may specify a non-zero -width in the style.
WIDGET COMMAND
In addition to the standard cget, configure, identify, instate, and state commands, buttons support the following additional widget commands:
- pathName invoke
- Invokes the command associated with the button.
COMPATIBILITY OPTIONS

- Database Name: state
