Conception for a table with 1st row as a filter

[Ch4rles]

Hi,
I want to setup a table with a filter for each column. I want those filters (a regex string) to stay on the 1st row (or be direclty integrated in the header but I don't think that would be simplier).
I have a working QAbstractTable and a QTableView. And I would like to set the filters in a QAbstractProxyModel. I've been experimenting with QSortFilterProxyModel by adding a row and shifting the row index from/to the model. But those classes are made to hide data from the model not add to it. So I'm having troubles with index management. I keep looking and I might ask a question about that later.
But right now, I would like your thoughts on the conception/patterns. Is this the right way to do it ? Do you have other ideas ?
Thanks,

Square peg, round hole? :) You'd be better doing it in the header. But admit I don't know how to, how much can you do with QHeaderView?

Hi and welcome to devnet,

Do you mean you want to filter each column independently ?

[Ch4rles]

@SGaist To be honest the principle is the same as the filters you can set in LIbreoffice or Excel. The main difference is that I want to use regex.
So if any cell doesn't match to the filter of its column the whole row is hidden.

You might want to use a technique similar to the one shown in the frozen column example.

@SGaist Thanks, that's a great tip! I didn't know this example, I'll definitely use it in the end.
What about the idea of keeping the filters away from the model by using a proxy ? Do you think that's the right path ?
