In kde 4.6.1 I want to use http://api.kde.org/4.x-api/kdelibs-apidocs/kio/html/classKAbstractFileItemActionPlugin.html

because:

However if you need some dynamic logic, like "only show this item if two files are selected", or "show a submenu with a variable number of actions", then you have to implement a KAbstractFileItemActionPlugin subclass.

But I don't find any script with this fonction.
Can you help me?

thank

It seems that Dolphin and Konqueror both support this, although I couldn't find any examples in KDE source repositories. http://lxr.kde.org/ident?i=KAbstractFil ... tionPlugin

According to that documentation, you need to subclass and then reimplement actions() in that subclass.
