usual

usual declaration for the standard Tk button widget: 
usual Button {
    keep -background -cursor -foreground -font
    keep -activebackground -activeforeground -disabledforeground
    keep -highlightcolor -highlightthickness
    rename -highlightbackground -background background Background
}

Only the options that would be common to all buttons in a single mega-widget are kept or renamed. Options like "-text" that would be unique to a particular button are ignored.

 

usual :  access default option-handling commands.
