Hello,

we are developing Qt applications. kdevelops debugger offers a watch where=
=20
it can display QStrings. I am more the commandline user and have found a=20
nice function that prints QStrings with gdb:

define pqs
    set $i=3D0
    set $unicode=3D$arg0.d->unicode

    printf "Getting QString...\n"
    while $i < $arg0.d->len
        set $c=3D$unicode[$i++].ucs
        if $c < 32=20
          printf "\\0%o", $c
        else
          if $c <=3D 127
            printf "%c", $c
          else=20
            printf "\\0%o", $c
          end=20
        end
    end
    echo \n
end

(gdb) pqs oszPrinterLine
Getting QString...

Works fine - except that it takes ages (25s) ! Kdevelop displays the=20
QStrings in an instant. Now I wonder if there is a faster way of getting=20
this information in gdb - and maybe even to "display oszPrinterLine" which=
=20
makes sense only if printing is fast... ?

Mit freundlichen Gr=FC=DFen
