Solved QTableView give columnwidth a percentage and keep percentage when table gets wider
-
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,

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.
