WIDGET-SPECIFIC METHODS

pathName cget option
Returns the current value of the configuration option given by option. Option may have any of the values accepted by the finddialog command.

pathName clear
Clears the pattern in the entry field and the pattern matchin indicators in the text or scrolledtext widget.

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 available 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 finddialog command.

pathName find: Search for a specific text string in the text widget given by the -textwidget option. This method is the standard callback for the Find button. It is made available such that it can be bound to a find again action.
