Ok. Adding a method to KGlobalAccel would make it possible to do what you want. But with a major 
problem. You use the method by using internal and private kwin information. Internal Information 
like the component name and the actions objectname. Those become more or less part the public api of 

Currently kwin can decide to change one or the other and only has to worry about kglobalaccel and 
remove the old registrations. If we add such a function this is no longer true.

Example given: One of these days i would like to move the "block global shortcuts" action from kwin 
to kglobalaccel. Your app would silently stop to work if that was the shortcut you look for.

This would break applications using that method silently. No error. You just get back an empty 
shortcut because the method cannot assume not finding the asked for shortcut is an error.

That's why i'm kind of cautios with adding such a method to our public api.

If both parts of code are more or less considered part of the same program i would propose the 
kaction hack. But i guess ksysguard and kwin cannot be considered the same app or evgen tightly 

If we would talk about an class and someone wanted to have access to an internal kaction i would say 
provide an api to get it. The equivalent here would be to add such an api to kwin (probably over 
dbus). Which sounds equally dumb and not really right but if you ask me the most correct solution. 
You want access to an kwin internal. And kwin will know you do.

But i won't reserve the right to decide here. So everyone with an opinion should chip in. I guess 
the problem will come up from time to time so we should 

We could say changing the component name is higly unlikely. With the exception of plasma it never 
happened as far as i know. Changing the objectname of a global shortcut is equally unlikely but not 

So the question is. Which bad do we chose?
