  • Error in capturing selection

    From Luc@21:1/5 to All on Thu Feb 2 03:43:50 2023
    $::bottomtextbox insert end "\n[$::HASFOCUS tag ranges sel]"

    Type abcdef

    Highlight. It prints:

    1.0 1.6

    So it doesn't give me the text. It gives me the indices of the
    selection. OK then:

    $::bottomtextbox insert end "\n[$::HASFOCUS get [$::HASFOCUS tag ranges sel]]"

    Can't even type. It throws an error:

    bad text index ""
    while executing
    "$::HASFOCUS get [$::HASFOCUS tag ranges sel]"


    What am I doing wrong this time?

    The get requires 2 arguments and the 'tag ranges sel' returns a list of 2 items so you need the {*} operator to expand the list into 2 arguments
    [$::HASFOCUS get {*}[$::HASFOCUS tag ranges sel]]
