I am using Qt to display a bunch of information in a table. I have a QTableWidget object and some of the header titles I want to include are longer than what I want the cell sizes to be. For example, I would like to have 

<html> <br>Acceleration <br> (m/s^2) </html>

instead of having both on the same line. I know there is a word wrap capability in the cells, but I would like to keep the titles in the header so they can be distinguished more easily. HTML in the strings doesn’t seem to work in the header either so I can’t use a <br>. Is there a way to get text to wrap, or manually break lines within the title?

    You could use a simple \n to manually break your header title:

    #include <QApplication>
#include <QTableWidget>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QTableWidget w(2, 2);
    w.setHorizontalHeaderLabels(QStringList() << "FOO\nBAR" << "FOOBAR");
    w.show();

    return app.exec();
}
