Database name: underline
Database class: Underline

If option is specified with no value, then the command returns a list describing the named option: the elements of the list are the option name, database name, database class, default value, and current value. If no option is specified, returns a list describing all of the available options for pathName.
pathName cget option
Returns the current value of the configuration option given by option.
pathName identify element x y
Returns the name of the element under the point given by x and y, or an empty string if the point does not lie within any element. x and y are pixel coordinates relative to the widget. Some widgets accept other identify subcommands.
pathName instate statespec ?script?
Test the widget’s state. If script is not specified, returns 1 if the widget state matches statespec and 0 otherwise. If script is specified, equivalent to
pathName state ?stateSpec?
Modify or inquire widget state. If stateSpec is present, sets the widget state: for each flag in stateSpec, sets the corresponding flag or clears it if prefixed by an exclamation point. Returns a new state spec indicating which flags were changed:
