Описание тега qtreewidget

This class uses a standard model to hold items, each of them being a QTreeWidgetItem.

Before adding data into the widget, a column count must be specified with setColumnCount() function. The widget can also have a header with a section for each of the columns. It also supports column-based sorting.

A simple example of using this class looks like this:

 //creating a widget
 QTreeWidget *myTreeWidget = new QTreeWidget();
 //adding a column to it
 myTreeWidget->setColumnCount(1);
 //creating a container to temporarily hold the items
 QList<QTreeWidgetItem *> itemList;
 //filling the container with items
 for (int i = 0; i < 10; ++i)
     itemList.append(new QTreeWidgetItem((QTreeWidget*)0, QStringList(QString("item: %1").arg(i))));
 //finally, setting the items into the widget.
 myTreeWidget->insertTopLevelItems(0, itemList);
