QTableWidget ¶

概要 ¶

详细描述 ¶

Table widgets provide standard table display facilities for applications. The items in a QTableWidget are provided by QTableWidgetItem .

若希望表格使用您自己的数据模型，应使用 QTableView 而不是此类。

可以采用所需行数和列数构造表格 Widget：

tableWidget = new QTableWidget(12, 3, this);
											

另外，可以在不给定尺寸的情况下构建表格并稍后重置尺寸：

tableWidget = new QTableWidget(this);
tableWidget->setRowCount(10);
tableWidget->setColumnCount(5);
											

Items are created outside the table (with no parent widget) and inserted into the table with setItem() :

QTableWidgetItem *newItem = new QTableWidgetItem(tr("%1").arg(
    (row+1)*(column+1)));
tableWidget->setItem(row, column, newItem);
											

If you want to enable sorting in your table widget, do so after you have populated it with items, otherwise sorting may interfere with the insertion order (see setItem() 了解细节)。

Tables can be given both horizontal and vertical headers. The simplest way to create the headers is to supply a list of strings to the setHorizontalHeaderLabels() and setVerticalHeaderLabels() functions. These will provide simple textual headers for the table’s columns and rows. More sophisticated headers can be created from existing table items that are usually constructed outside the table. For example, we can construct a table item with an icon and aligned text, and use it as the header for a particular column:

QTableWidgetItem *cubesHeaderItem = new QTableWidgetItem(tr("Cubes"));
cubesHeaderItem->setIcon(QIcon(QPixmap(":/Images/cubed.png")));
cubesHeaderItem->setTextAlignment(Qt::AlignVCenter);
											

The number of rows in the table can be found with rowCount() , and the number of columns with columnCount() . The table can be cleared with the clear() 函数。
