This class is used to provide standard tables that were - previously provided by the QTable class, but using the more - flexible approach provided by Qt's model/view architecture. - - The QTableView class is one of the \l{Model/View Classes} - and is part of Qt's \l{Model/View Programming}{model/view framework}. - - QTableView implements the interfaces defined by the - QAbstractItemView class to allow it to display data provided by - models derived from the QAbstractItemModel class. - - \section1 Navigation - - You can navigate the cells in the table by clicking on a cell with the - mouse, or by using the arrow keys. Because QTableView enables - \l{QAbstractItemView::tabKeyNavigation}{tabKeyNavigation} by default, you - can also hit Tab and Backtab to move from cell to cell. - - \section1 Visual Appearance - - The table has a vertical header that can be obtained using the - verticalHeader() function, and a horizontal header that is available - through the horizontalHeader() function. The height of each row in the - table can be found by using rowHeight(); similarly, the width of - columns can be found using columnWidth(). Since both of these are plain - widgets, you can hide either of them using their hide() functions. - - Rows and columns can be hidden and shown with hideRow(), hideColumn(), - showRow(), and showColumn(). They can be selected with selectRow() - and selectColumn(). The table will show a grid depending on the - \l showGrid property. - - The items shown in a table view, like those in the other item views, are - rendered and edited using standard \l{QItemDelegate}{delegates}. However, - for some tasks it is sometimes useful to be able to insert widgets in a - table instead. Widgets are set for particular indexes with the - \l{QAbstractItemView::}{setIndexWidget()} function, and - later retrieved with \l{QAbstractItemView::}{indexWidget()}. - - \table - \row \o \inlineimage qtableview-resized.png - \o By default, the cells in a table do not expand to fill the available space. - - You can make the cells fill the available space by stretching the last - header section. Access the relevant header using horizontalHeader() - or verticalHeader() and set the header's \l{QHeaderView::}{stretchLastSection} - property. - - To distribute the available space according to the space requirement of - each column or row, call the view's resizeColumnsToContents() or - resizeRowsToContents() functions. - \endtable - - \section1 Coordinate Systems - - For some specialized forms of tables it is useful to be able to - convert between row and column indexes and widget coordinates. - The rowAt() function provides the y-coordinate within the view of the - specified row; the row index can be used to obtain a corresponding - y-coordinate with rowViewportPosition(). The columnAt() and - columnViewportPosition() functions provide the equivalent conversion - operations between x-coordinates and column indexes. - - \section1 Styles - - QTableView is styled appropriately for each platform. The following images show - how it looks on three different platforms. Go to the \l{Qt Widget Gallery} to see - its appearance in other styles. - - \table 100% - \row \o \inlineimage windowsxp-tableview.png Screenshot of a Windows XP style table view - \o \inlineimage macintosh-tableview.png Screenshot of a Macintosh style table view - \o \inlineimage plastique-tableview.png Screenshot of a Plastique style table view - \row \o A \l{Windows XP Style Widget Gallery}{Windows XP style} table view. - \o A \l{Macintosh Style Widget Gallery}{Macintosh style} table view. - \o A \l{Plastique Style Widget Gallery}{Plastique style} table view. - \endtable - - \sa QTableWidget, {View Classes}, QAbstractItemModel, QAbstractItemView, - {Chart Example}, {Pixelator Example}, {Table Model Example} -*/ - -/*! - Constructs a table view with a \a parent to represent the data. - - \sa QAbstractItemModel -*/ - -QTableView::QTableView(QWidget *parent) - : QAbstractItemView(*new QTableViewPrivate, parent) -{ - Q_D(QTableView);
