|---|---|---|
| -command | command | Command |
| A script to evaluate when the widget is invoked. | ||
| -default | default | Default |
| May be set to one of normal, active, or disabled.
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 disabled.
Depending on the theme, the default button may be displayed with an extra highlight ring, or with a different border color. |

| Specifies the name of variable, whose value will be used in place of the -text resource. | ||
| -underline | underline | Underline |
| Specifies the integer index (0-based) of a character to underline in the widget. The underlined character is used for mnemonic activation (see keynav(n)). | ||
| -width | width | 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. | ||
