faster printing of QStrings

[Markus.Grunwald@pruftechnik.com]

Hello,

we are developing Qt applications. kdevelops debugger offers a watch where 
it can display QStrings. I am more the commandline user and have found a 
nice function that prints QStrings with gdb:

define pqs
    set $i=0
    set $unicode=$arg0.d->unicode

    printf "Getting QString...\n"
    while $i < $arg0.d->len
        set $c=$unicode[$i++].ucs
        if $c < 32 
          printf "\\0%o", $c
        else
          if $c <= 127
            printf "%c", $c
          else 
            printf "\\0%o", $c
          end 
        end
    end
    echo \n
end

(gdb) pqs oszPrinterLine
Getting QString...

Works fine - except that it takes ages (25s) ! Kdevelop displays the 
QStrings in an instant. Now I wonder if there is a faster way of getting 
this information in gdb - and maybe even to "display oszPrinterLine" which 
makes sense only if printing is fast... ?
