Detailed Description

../../_images/windows-tableview.png

A QTableView implements a table view that displays items from a model. 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 Model/View Classes and is part of Qt’s 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.

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 showGrid property.

The items shown in a table view, like those in the other item views, are rendered and edited using standard 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 setIndexWidget() function, and later retrieved with indexWidget() .

qtableview-resized1

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 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.

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.
