Hello, thank you for your answer. But it's not. I have read all installer framework documentation and found nothing. And there is not a radio button, because it can be the third component C that haven't some connection with A and B. Moreover, it can be a set of components that have some subset F that should auto enable A or be enabled by A. And another subset G that can have elements from F, but enable B or be enabled by B. Auto-dependenecy in this case is simply remove all checkboxes(what a shame). Or some elements can be added dynamically to repository, it's online installer. I don't see any necessary of custom UI creation of page that already exist. What i want is some method to interact with checkboxes on Component Selection Page. I know that scripts should be helpful, but doesn't understand how to interact with checkboxes throw it. I try to find some signal but doesn't succeed. It seems that creation of my own online installer will be more quicker than understanding of qt.
P.S. Please don't send me Dependency Solving Example page, it's not what I needed. It can't work with subsets.
P.P.S. And I don't want duplicate components without greater need.
