The left and right listboxes are instances of the ListboxWidget(n) class and have the Itcl component names left and right .

Example:

 
itk_component add dlist { 
    DoubleList $w_.dtlist \ 
    -lefttitle "Keep" \ 
    -righttitle "Don't Keep" \ 
    -hscroll 1 \ 
    -updown 1 \ 
    -selectmode extended 
} 
pack $itk_component(dlist) -fill both -expand 1 
 
[$itk_component(dlist) component left] set_contents \ 
    {one two three four five six} 
[$itk_component(dlist) component right] set_contents \ 
    {seven eight nine ten}
