i mostly like this patch ...

however, QueryActionPool doesn't seem to actually be used; where it is used, it seems to be an implementation detail and therefore shouldn't need to be exported .. but even more evident is that it probably isn't needed at all?

what plans do you have for QueryActionPool, if any?

(without QueryActionPool, QueryAction seems unecessary as well?)

    setting a title on a QMenu doesn't actually do anything unless the menu is put into a submenu; KMenu lets you put a visible title in a menu, if that's what you're looking for.
    
    if the menu title is visible in the menu itself (as opposed to a sub-menu entry that shows the menu), it should contain the name of the action. i18n("Actions For '%1'", name()) or something like that ...

    for applications that use runners internally, versus an application like krunner which is only about runners, the constructor will be used (think of multiple kickoff applets, for instance?); perhaps the apidox should be altered to make self() sound less required =)

    "current" sounds like an iterator; perhaps "selected" or "active"? setSelectedAction sounds good to me ..

The object of the action would be a directory. I'm still looking for ways to implement this. One way would be to have a set of core runners designated as object providers (e.g. Places, Contacts) and run a secondary query on a specific runner.

After creation, QueryActions must be registered with QueryActionPool, the global action registry. This allows QueryActions to only be created once during the lifetime of a runner. This also allows runners to add actions that belong to different runners. However, correct execution of the action is left up to the runner in the exec method. I'll provide an example of how to do this soon.

Note, the temporary solution triggers the action upon selection the action in the context menu. Pressing enter or clicking on the icon will cause the action to be performed again.
