Command-Line Name: -command
Database Name: command
Database Class: Command: A script to evaluate when the widget is invoked.
Command-Line Name: -default
Database Name: default
Database Class: 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 normal.

Depending on the theme, the default button may be displayed with an extra highlight ring, or with a different border color.

Command-Line Name: -width
Database Name: width
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:

COMPATIBILITY OPTIONS

Command-Line Name: -state
Database Name: state
Database Class: State: May be set to normal or disabled to control the disabled state bit. This is a

“write-only” option: setting it changes the widget state, but the state widget command does not affect the state option.
