Description

The iwidgets::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 conjunc- tion with the selection box.

Methods

The iwidgets::selectionbox command creates a new Tcl command

whose name is pathName. This command may be used to invoke vari- ous 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.

pathName clear component
