In Qt, how to resize icons in a table?

Question

I put icons as items in a table:

QTableWidget *table = new QTableWidget(this);
QTableWidgetItem *item = new QTableWidgetItem;
item->setSizeHint(QSize(100, 100));
item->setIcon(QIcon(fileName));
table->setItem(0, 0, item);

However no matter the icons' size, they are shown extremely small in the table.
I do not care about the text.

How can I get them bigger?

You need to change the size of the icons in the QTableWidget. You can do so using the iconSize property inherited from QAbstractItemView. See here.

QTableWidget *table = new QTableWidget(this);
table->setIconSize(QSize(100, 100));
QTableWidgetItem *item = new QTableWidgetItem;
item->setSizeHint(QSize(100, 100));
item->setIcon(QIcon(fileName));
table->setItem(0, 0, item);
