How can I find subitems in a QTreeWidget using findItems?

In order to find subitems in a QTreeWidget using findItems() [doc.qt.nokia.com] you need to specify the Qt::MatchRecursive [qt.nokia.com] flag.

The following example illustrates how this can be done:

#include <QtGui>
int main( int argc, char** argv )
{
QApplication app( argc, argv );
QTreeWidget* treeWidget = new QTreeWidget;
treeWidget->setWindowTitle("Test");
treeWidget->setColumnCount(4);
QTreeWidgetItem* item = NULL;
for (int l=0; l<10; l++)
{
item = new QTreeWidgetItem(treeWidget);
item->setText(0, QString::number(l));
item->setText(1, QString::number(l));
item->setText(2, QString::number(l));
item->setText(3, "test");
item->setFlags( Qt::ItemIsUserCheckable | Qt::ItemIsSelectable | Qt::ItemIsEnabled );
item->setCheckState(0, Qt::Unchecked);
}
QList<QTreeWidgetItem*> items = treeWidget->findItems("test",Qt::MatchExactly, 3);
int num = items.count();
qDebug("first time: %d", num);
for (int l=0; l<5; l++)
{
item = new QTreeWidgetItem(treeWidget->topLevelItem(4));
item->setText(0, QString::number(l));
item->setText(1, QString::number(l));
item->setText(2, QString::number(l));
item->setText(3, "test");
item->setFlags( Qt::ItemIsUserCheckable | Qt::ItemIsSelectable | Qt::ItemIsEnabled );
item->setCheckState(0, Qt::Unchecked);
}
treeWidget->show();
items = treeWidget->findItems("test", Qt::MatchExactly, 3);
items = treeWidget->findItems("test", Qt::MatchExactly | Qt::MatchRecursive, 3);
num = items.count();
qDebug("Second time: %d", num);
return app.exec();
}
