I would like to add a GroupSummaryView like component that could contains Widget instead of only render numbers.
I digged into the code to find out a solution but the only thing I found yet is adding html code in the doGroupEnd() method of the GroupingView class.
I want to put a button at the end of each group in my grid. So, I still need to find out how to attach listener to this html rendered button.
It would be appreciated if someone has a more elegant solution for adding a GXT button (or any other GXT widget) directly instead.
