in kde how can I get the current activity name by command line in konsole?
the one shown by the “cashwe” or what else its name placed in the upper right corner of screen :slight_smile:
many thanks, ciao, pier :slight_smile:

Why do you want that?

You can get the ID of the current activity e.g. via:

qdbus org.kde.ActivityManager /ActivityManager/Activities CurrentActivity

You can get the name of a certain activity like this:

qdbus org.kde.ActivityManager /ActivityManager/Activities ActivityName *$ID*

($ID specifies the ID of the activity from which you want to get the name)

Combine this to get the name of the current activity:

qdbus org.kde.ActivityManager /ActivityManager/Activities ActivityName `qdbus org.kde.ActivityManager /ActivityManager/Activities CurrentActivity`

:wink:

Maaanythanks, at the end wasn’t so easy :-), I want to have the activity name showed in a more readable way and I cannot easy modify the object in the upper right of the screen, so I will do a plasmoid that shows the activity name… :slight_smile: or is there a better way??

Well, if you are going to write a plasmoid, you could probably use DBUS directly instead of by calling the program “qdbus”.

Depending on which language you use, you could probably also use Plasma’s functions directly.

But as this question is completely KDE specific (rather low-level even) and has nothing to do with openSUSE, you should probably better ask in the KDE forums/mailinglists…

uh, I’m not so skilly to kwon what to do to write a plasmoid…:), I only modify a python plasmoid

I found in the net or use stdin-plasmoid, but it could be a good idea to ask to kde people …:slight_smile:
