QTableWidget display certain number of rows at a time

Question

I have a large qtablewidget. Let's say 200 rows. In QListWidget, there is setMaxVisibleItems(30), which is extremely useful. What's the equivalent for a qtablewidget, except for rows. Ie. setMaxVisibleRows?

I considered setting a max height for my window. However, this application can be used on varying DPIs. So, it may be small for some. Plus, that felt like a needless restriction.

I also saw this: How to show only 30 rows and hide the remaining rows of QTableWidget

However, it isn't the same by any means.

Thank you very much in advanced!

Answer 1

The best way I would do it is to use Qt's void QTableView::setRowHidden(int row, bool hide)

void QTableView::setRowHidden(int row, bool hide):

If hide is true row will be hidden, otherwise it will be shown.

If you know the count of your table you can use that othewise you will have to use a model and use rowCount() .

Then the for loop should be easy:

for(int i = startHidingHere; i < numOfRows; i++)
    myTable->setRowHidden(i, true);

You can obviously do a similar method to un-hide them. This method also works great for filters if needed in the future.

Other possible useful methods:

bool QTableView::isRowHidden(int row);

void QTableView::setColumnHidden(int column, bool hide);

void QTableView::setModel(QAbstractItemModel *model);
->   int QAbstractItemModel::rowCount(const QModelIndex & parent = QModelIndex()) const
