--- Comment #6 from Nicolas Bigaouette <nbigaouette gmail com>  2010-08-31 19:36:24 ---
I am highly interested in such a feature. I'm using KDE 4.4.5 for now. I have
many virtual desktops and open files mostly from the command line. I want to
open the files in the session on the actual desktop.

This is a wish I had for a long time (pre KDE4) and IIRC, at some point (maybe
4.3 or 4.2?) the behavior seemed to have been what I wanted and I though it was
fixed. I though people had worked on this and so I forgot about it. But now, if
I open a file from a terminal, it will always open it in the first session
reported by dbus. For example:
$ kate file.txt
org.kde.kate-17443running instance:Session 1
org.kde.kate-14557running instance:Session 2
will always open the file in "Session 1".

Now I have hacked something in bash to open a file in kate window of the active
desktop. Basically I find the PID of kate that runs on the current desktop and
launch kate using "--pid":
#!/bin/bash

current_desktop=`wmctrl -d | grep "*" | awk '{print $1}'`
echo "current_desktop = ${current_desktop}"

pid=`wmctrl -l -p | grep Kate | sed "s|.*  ${current_desktop} \([0-9]*\)
.*|\1|g" | grep -v 0x`
echo "Kate on current desktop has PID ${pid}"

if [[ "x${pid}" == "x" ]]; then
    kate ${@}
else
    kate --pid ${pid} ${@}
fi

I now have a bash alias pointing to that script.

Couldn't something similar be included directly in kate? I tried to do the same
thing using qdbus but couldn't not find how (don't know much about dbus/qdbus).
But if it's possible to get that information from dbus, couldn't kate use that
information?

Bug #128193 should be merged here I think.
