I have an application that has a number of built in shortcuts. I am adding a new one for showing / hiding the application at the OS level (for example Ctrl+Shift+D would open my app even if it's not in focus) - this short cut is user editable, so it can be defined as whatever people like.

I don't want this user defined shortcut to conflict with any we are already using.

So my question is, is there a way in Qt to get the list of already registered shortcuts? Or do I need to start manually maintaining an in-use shortcut list?
