QTableView give columnwidth a percentage and keep percentage when table gets wider

Asimov

I have looked at various posts on this, but not found a solution.
I am using a model in a QTableView.

At the moment I am not setting column widths, but just stretching the righthand column.

ui->contentTable->horizontalHeader()->stretchLastSection();

What I really want to do is this. I have a two column table.
I want to give the first column 20% width and the second column 80% width.

When the table expands I want them to keep these width percentages, but expand.

I have tried

 ui->contentTable->horizontalHeader()->setSectionResizeMode(2, QHeaderView::Stretch);
  ui->contentTable->horizontalHeader()->setSectionResizeMode(3, QHeaderView::Stretch);

But this just make equal size columns.
By the way 2 and 3 is not an error, as the first column is hidden because that is where I store the id for sqlite.

I have tried setting the second column width like this

ui->contentTable->setColumnWidth(2,100);

but this isn't a percentage and stays fixed at this width.

So is there a way of using percentages for table column widths?

Hi,

The solution described here might be of interest.

@SGaist
Strangely enough I found this page while searching, but none of the solutions on the page seemed to work.

However I have re-looked at the page and this is my solution to my problem.

I set the last column to stretch like before

ui->contentTable->horizontalHeader()->setSectionResizeMode(3, QHeaderView::Stretch);

and then I use a bit of code off the other page you gave me.

void MainWindow::resizeEvent(QResizeEvent *event) {
    ui->contentTable->setColumnWidth(2, this->width()/5);
    QMainWindow::resizeEvent(event);
}

This gives me a wider first column which is column 2 and it stretches in proportion to the full screen.

Thanks, this is solved.
My new app is nearly finished.
