pathName cget option

Returns the current value of the configuration option given by

option. Option may have any of the values accepted by the mes- sagedialog command.
pathName configure ?option? ?value option value ...?

Query or modify the configuration options of the widget. If no

option is specified, returns a list describing all of the avail- able options for pathName (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no option is specified). If one or more option-value pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the messagedialog command.
