\class QTableView
|

|
|
|
900 |
\brief The QTableView class provides a default model/view
|
|
|
901 |
implementation of a table view.
|
|
|
902 |
|
|
|
903 |
\ingroup model-view
|
|
|
904 |
\ingroup advanced
|
|
|
905 |
|
|
|
906 |
|
|
|
907 |
A QTableView implements a table view that displays items from a
|
|
|
908 |
model. This class is used to provide standard tables that were
|
|
|
909 |
previously provided by the QTable class, but using the more
|
|
|
910 |
flexible approach provided by Qt's model/view architecture.
|
|
|
911 |
|
|
|
912 |
The QTableView class is one of the \l{Model/View Classes}
|
|
|
913 |
and is part of Qt's \l{Model/View Programming}{model/view framework}.
|
|
|
914 |
|
|
|
915 |
QTableView implements the interfaces defined by the
|
|
|
916 |
QAbstractItemView class to allow it to display data provided by
|
|
|
917 |
models derived from the QAbstractItemModel class.
|
|
|
918 |
|
|
|
919 |
\section1 Navigation
|
|
|
920 |
|
|
|
921 |
You can navigate the cells in the table by clicking on a cell with the
|
|
|
922 |
mouse, or by using the arrow keys. Because QTableView enables
|
|
|
923 |
\l{QAbstractItemView::tabKeyNavigation}{tabKeyNavigation} by default, you
|
|
|
924 |
can also hit Tab and Backtab to move from cell to cell.
|
|
|
925 |
|
|
|
926 |
\section1 Visual Appearance
|
|
|
927 |
|
|
|
928 |
The table has a vertical header that can be obtained using the
|
|
|
929 |
verticalHeader() function, and a horizontal header that is available
|
|
|
930 |
through the horizontalHeader() function. The height of each row in the
|
|
|
931 |
table can be found by using rowHeight(); similarly, the width of
|
|
|
932 |
columns can be found using columnWidth(). Since both of these are plain
|
|
|
933 |
widgets, you can hide either of them using their hide() functions.
|
|
|
934 |
|
|
|
935 |
Rows and columns can be hidden and shown with hideRow(), hideColumn(),
|
|
|
936 |
showRow(), and showColumn(). They can be selected with selectRow()
|
|
|
937 |
and selectColumn(). The table will show a grid depending on the
|
|
|
938 |
\l showGrid property.
|
|
|
939 |
|
|
|
940 |
The items shown in a table view, like those in the other item views, are
|
|
|
941 |
rendered and edited using standard \l{QItemDelegate}{delegates}. However,
|
|
|
942 |
for some tasks it is sometimes useful to be able to insert widgets in a
|
|
|
943 |
table instead. Widgets are set for particular indexes with the
|
|
|
944 |
\l{QAbstractItemView::}{setIndexWidget()} function, and
|
|
|
945 |
later retrieved with \l{QAbstractItemView::}{indexWidget()}.
|
|
|
946 |
|
|
|
947 |
\table
|
|
|
948 |
\row \o \inlineimage qtableview-resized.png
|
|
|
949 |
\o By default, the cells in a table do not expand to fill the available space.
|
|
|
950 |
|
|
|
951 |
You can make the cells fill the available space by stretching the last
|
|
|
952 |
header section. Access the relevant header using horizontalHeader()
|
|
|
953 |
or verticalHeader() and set the header's \l{QHeaderView::}{stretchLastSection}
|
|
|
954 |
property.
|
|
|
955 |
|
|
|
956 |
To distribute the available space according to the space requirement of
|
|
|
957 |
each column or row, call the view's resizeColumnsToContents() or
|
|
|
958 |
resizeRowsToContents() functions.
|
|
|
959 |
\endtable
|
|
|
960 |
|
|
|
961 |
\section1 Coordinate Systems
|
|
|
962 |
|
|
|
963 |
For some specialized forms of tables it is useful to be able to
|
|
|
964 |
convert between row and column indexes and widget coordinates.
|
|
|
965 |
The rowAt() function provides the y-coordinate within the view of the
|
|
|
966 |
specified row; the row index can be used to obtain a corresponding
|
|
|
967 |
y-coordinate with rowViewportPosition(). The columnAt() and
|
|
|
968 |
columnViewportPosition() functions provide the equivalent conversion
|
|
|
969 |
operations between x-coordinates and column indexes.
|
|
|
970 |
|
|
|
971 |
\section1 Styles
|
|
|
972 |
|
|
|
973 |
QTableView is styled appropriately for each platform. The following images show
|
|
|
974 |
how it looks on three different platforms. Go to the \l{Qt Widget Gallery} to see
|
|
|
975 |
its appearance in other styles.
|
|
|
976 |
|
|
