  • Shift-Tab binding not working

    From Luc@21:1/5 to All on Tue Dec 5 22:32:04 2023
    I have a long series of text widget boxes.

    When I press Tab, the focus jumps from one box to the next one.

    When I press Shift+Tab, the focus jumps from one box to the previous one.

    Other things happen too, but they are not relevant now except that they
    only happen when I jump forward, never when I jump backwards.

    Jump forward and jump backwards have different proc sections and I could determine that the jump backwards section is never run.

    These are my bindings:

    bind [set ::target_$x] <Tab> {p.navigate "down"; break}
    bind [set ::target_$x] <Shift_R><Tab> {p.navigate "up"; break}

    Any idea on how I can find out why one section is never run? They are
    stated one right after the other and there is no 'return' or loop break/continue command involved.

    In fact, I put a debug statement right at the fiirst line of the proc
    like puts $action and the "up" action never turns up. The "down" action
    turns up every time.

    The second binding is not working. Why?

    Since you should use <Shift><Tab> instead. <Shift_R> is the actual key,
    but <Shift> the qualifier state.

    Hi

    Try:

    ## script start
    pack [entry .en]
    bind .en <Key> "tuwas %K"

    proc tuwas {args} {
    puts "the key is $args"
    }


    ## script end

    Now fous .en

    Press <Shift><Tab>

    Now you'll see the keysum.

    I my case on linux it's ISO_Left_Tab


    Regards

    No.

    bad event type or keysym "Shift"
    while executing
    "bind [set ::target_$x] <Shift><Tab> {p.navigate "up"; break}"

    Yes. That works.

    A little strange that both the left and the right Shift keys generate ISO_Left_Tab.

    But OK, that works for me.

    Problem solved. Thank you.

    That is because it is not referring to the key, but rather the action
    the key signifies. It is indicating do the action of "tabbing to the
    left".

    Hello

    ##
    pack [entry .en]
    bind .en <Key> "tuwas %K"

    proc tuwas {key} {
    if {$key eq "Shift_L"} {set ::mylastshiftkey Shift_L}
    if {$key eq "Shift_R"} {set ::mylastshiftkey Shift_R}
    if {$key ne "ISO_Left_Tab" || $::mylastshiftkey ne "Shift_L"} {return}
    ##Your code##
    puts "<Shift-Left><Tab> pressed"
    }
    ##

    With this code only <Shift_L><Tab> works

    regards

    Manfred
