That is strange because I think I have done that in 3.1.4 with kmail running and it didn't complain. Maybe you should post a bug or check if now we are supposed to do something like kontact --composer.

I can only check this later.

If you have kmail running, you can open a composer window with DCOP.
You can even prefill some fields.

#> dcop kmail default openComposer "" "" "" "" "" 0 ""
opens an empty composer

#> dcop kmail default openComposer "toaddress@somewhere.com" "" "" "DCOP rules" "" 0 ""

opens composer with To address and subject already set

dcop scripting can be really helpfull but there isn't much documentation around (I can be missing something).
Sometime ago there was a post about how to lock the screen from the shell. Again the solution was dcop.

Is there any standard way of knowing what can be used from an aplication? I have already used kdcop.
If an appliation provides dcop hooks why do they make them "secret"? (ATTENTION: kde API and development philosophy illiterate)

Thanks for the help, but I am still having trouble. I shoudl have mentioned this but I am using KDE 3.1 and the preliminary source version of Kontact (not the one that comes with KDE 3.2).

Here's what happens:
I type :
dcop kmail default openComposer "" "" "" "" "" 0 ""
I get the following msg:
object not accessible

Hmm, maybe the name is different.
#> dcop
will list all DCOP enabled applications currently available, perhaps the name of KMail has changed.

#> dcop processname
lists all interfaces available from this application, one is usually calles default, so it can be accessed through "default" and through its name.

#> dcop processname interfacename
lists all functions available in the interface.
Each function has some parameters, QString means you can use any text within "", int is a number and, as in openComposer, KURL can be set like a QString.

There is a grafical tool called kdcop to browse applications DCOP interfaces.

I am a newbie so perhaps I am not typiing this in exactly correctly, but I was also unaware of an openComposer command after kmail. I thought it was just "--composer." Thanks!

Both are ok. --composer is a commandline option to the kmail executable, passed to it on startup.
dcop can be used to communicate with an application that is already running.

Not sure why, but it's working for now. I know it's not the best solution, but what the heck.

Could corrupt your mail files/folders if both kmail instances try to access them at the same time.

Currently only through looking by yourself, with kdcop for example.

Unfortunatel there is currently no documentation of applications' DCOP interfaces other then the documentation in the header files.

I am sure any effort in this direction will be highly welcomed.
One would need the applications sources and look into any header file which contains the "k_dcop" keyword.
The functions are usually documented but in style for developers
