clearSpans() for selected spans

[alex333]

Hi all!

clearSpans() in QTableView - removes all row and column spans in the table view.
How I can remove only selected spans?

Does calling setSpan(row, column, 1, 1) on the span you want to remove work?

Yes, it works...
but if I have selection, I can`t del span by this method (only using 'brute force of loop').
So, I think the best way - just clear all spans and rebuild it again without selected.

Why are you trying so hard to avoid looping over the cells in the selection, determining which ones are the top-leftmost in spanned cells, and resetting those? It seems your alternate is to iterate the entire to table to find which items are the top-leftmost item in a spanned area, storing those somewhere, clear all spans, then reinstate all the stored spans except those that would fall inside the selection. Perhaps I don't understand.

Why are you trying so hard

Good question.
This is because I have additional structure storing the spans. I don't need iterate entire table. So, rebuilding - wery simple for me, may be not most efficient, but simple.

Fair enough. That helps
