       in the list.

       in rows.  [-postcommand postCommand] A Tcl script to evaluate immediately before displaying the listbox.  The -postcommand script may spec-
       ify  the  -values  to  display.	 [-state state]  One of normal, readonly, or disabled.	In the readonly state, the value may not be edited
       directly, and the user can only select one of the -values from the dropdown list.   In  the  normal  state,  the  text  field  is  directly
       editable.  In the disabled state, no interaction is possible.  [-textvariable textVariable] Specifies the name of a variable whose value is
