## DESCRIPTION

The selectionbox command creates a scrolled list of items and a selection entry field. The user may choose any of the items displayed in the scrolled list of alternatives and the selection field will be filled with the choice. The user is also free to enter a new value in the selection entry field. Both the list and entry areas have labels. A child site is also provided in which the user may create other widgets to be used in conjunction with the selection box.

## METHODS

The selectionbox 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.

## 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 selectionbox command.
  pathName childsite
    Returns the child site widget path name.
  pathName clear component

  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 selectionbox command.
  pathName get
    Returns the current value of the selection entry widget.
