qdbus has no such helpfull interface, but this is the
command I use in
the script:
Cmd="/usr/bin/qdbus org.kde.kmail /KMail org.kde.kmail.kmail.checkMail"
There is a whole lot you can do with KMailIface,
kmail-mainwindow#1
(the current window), and MainApplication-Interface -- but
unfortunately there is nothing menu specific. It is pretty amazing all
that is there, but no rabbit to pull out of the dcop hat for kmail
menus.
We should grow a qdbus with those listing capabilities. The above one
liner, works about 99.99% of the time.
