## DESCRIPTION

The finddialog command creates a find dialog that works in conjunction with a text or scrolledtext widget to provide a means of performing search operations. The user is prompted for a text pattern to be found in the text or scrolledtext widget. The search can be for all occurances, by regular expression, considerate of the case, or backwards.

## METHODS

The finddialog command creates a new Tcl command whose name is pathName. This command may be used to invoke various operations on the widget. It has the following general form:

    pathName option ?arg arg ...?

Option and the args determine the exact behavior of the command. The following commands are possible for finddialog widgets:

## INHERITED METHODS

add invoke | buttonconfigure show | default | hide

See the "buttonbox" widget manual entry for details on the above inherited methods.

activate | center | deactivate |

See the "shell" widget manual entry for details on the above inherited methods.

## 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.
