Summary: disabled listbox error

Initial Comment:
Summary:
Listbox new disabled state seems not tested inside lisbox.tcl.

Test code:
  set ::listvar {a b c d e f g h i j}
  pack [listbox .lb -state disabled -listvar ::listvar -selectmode 
extended]

Result:
Browsing the listbox give an error:
expected boolean value but got ""
    while executing
"if {[$w selection includes anchor]} {
    $w selection clear $i $el
    $w selection set anchor $el
      } else {
    $w selection clear $i $el
    $w selecti..."
    ("extended" arm line 7)
    invoked from within
"switch [$w cget -selectmode] {
  browse {
      $w selection clear 0 end
      $w selection set $el
      set Priv(listboxPrev) $el
      event generate $w..."
    (procedure "tk::ListboxMotion" line 7)
    invoked from within
"tk::ListboxMotion .lb [.lb index @39,79]

Correction:
Don't know.
Should all events disabled when the listbox is disabled?

A workaround is to remove all bindings at disable:

        .lb configure -state disabled
        bindtags .lb {none}

and restore them at enable:

        .lb configure -state normal
        bindtags .lb {.lb Listbox . all}

Correction:
I written a clone of the Tk listbox.
It has not the problem because [cget -takefocus] returns false if 
the state is disabled.
