QTableView row height

Perdrix

I want to shrink the row height for all rows in the table view as there's more vertical white space around the contents than I would like:

something more like this is what I'm after:

I rapidly found setRowHeight() but that just sets it for ONE row, not all rows.

How should I do this please?
Thanks, David

Hi had the same problem but I just did a loop for all the rows, e.g.

int rowHeight = 28;
for (int r = 0; (r < ui->myTableWidget->rowCount()); ++r)
        ui->myTableWidget->setRowHeight(r,rowHeight);

@Perdrix , @hskoglund
To do this fixed for all rows --- so that e.g. it also applies whenever a new row is inserted --- you do it on QTableView->verticalHeader(). See https://stackoverflow.com/a/19304739 for example/discussion.

Thanks @JonB good to know

Except that my tableview doesn't have a vertical header... (or doesn't that matter)?

Every tableview has a vertical and a horizontal header.

So is this right?

//
// Reduce the row height somewhat
//
QHeaderView* verticalHeader = pictureList->tableView->verticalHeader();
double height = verticalHeader->defaultSectionSize();
height *= 0.8;
//verticalHeader->setSectionResizeMode(QHeaderView::Fixed);
verticalHeader->setDefaultSectionSize(height);

or do also need the setSectionResizeMode?

@Perdrix said in QTableView row height:

How do I find the default row height before any rows have been added?

Reading a documentation seems to be really hard for a lot of people... https://doc.qt.io/qt-6/qheaderview.html#defaultSectionSize-prop

@Perdrix
tableWidget->verticalHeader()->defaultSectionSize();
for me it's 30 pixels.

It's more a case of understanding WHERE you need to look - once you have the CORRECT part of the docs located, it's fine. Sometimes it's not always obvious.

PS I changed my post so it's now asking a different Q (that change crossed with your post).
