ReproducibleScript:
    set test "This entry can be activated and altered by pressing <TAB>"
    frame .f1
    frame .f2
    entry .f1.e -textvariable test
    button .f2.b -text "exit" -command "destroy .f1"
    pack .f1 -fill x
    pack .f2
    pack .f1.e -fill x
    pack .f2.b
    grab .f2
    tkwait window .f1
    puts $test
    exit
    
    Description: see below
    



ObservedBehavior:
    There is a grab on the frame of the Exit-Button. It should not be
    possible to alter the entry. It is in fact not possible to activate the
    entry by clicking on it, but if you press TAB, the entry becomes
    activated.
    
    I have a script, that starts a procedure, when you press <RETURN> in an
    entry. This should not happen, since I am trying to finish another
    activity (I have
    a grab on the necessary widgets), that should not be influenced by the
    other
    procedure (started by pressing <RETURN>).
    



DesiredBehavior:
    If there is a grab on a part of a window, it should not be possible to
    interact
    with other parts of the window!
    




The error the user reported is a litle mis guided, however it does reval a problem with grab on Windows.  Running the provided script on Unix and Windows will show the diufference.  Related bu ID 1268.  03/25/1999 15:49 - surles -

Comment:
Grabs don't affect keyboard focus (well, not really) and this is due to the way that Tk manages focus (the easiest alternative is *much* worse, as users of the Athena widget set can attest.)  Hence you have to take care of making sure that the focus is correctly managed yourself.
