I want to design a UI for linux Desktop. For this i will be needing following widgets / controls. I have searched and gone through the Qt resources but did not
find any satisfactory solution yet.

I want to use a grid that provides features like "filtering" & "grouping".

- I could not find any such grid in standard Qt widget or Qt Quick controls neither any open source implementation of the same.
- I have found a option but that is paid - QtitanDataGrid http://www.devmachines.com/qtitandatagrid-overview.html

1. Is anything similar available under Qt quick or Qt Widget ?

2. Also for complex Desktop application with multiple windows, views, grids, multiple threads and controls like grid, docking controls like Visual studio, slider/ splitter , which will be best to use Qt Quick or Qt Widgets (Only Desktop version is required , no future Mobile migration will be needed) ?

Thanks
