+ \class Q3DataTable
+ \brief The Q3DataTable class provides a flexible SQL table widget that supports browsing and editing.
+
+ \compat
+
+ Q3DataTable supports various functions for presenting and editing
+ SQL data from a \l Q3SqlCursor in a table.
+
+ If you want a to present your data in a form use QDataBrowser, or
+ for read-only forms, use QDataView instead.
+
+ When displaying data, Q3DataTable only retrieves data for visible
+ rows. If the driver supports the 'query size' property the
+ Q3DataTable will have the correct number of rows and the vertical
+ scroll bar will accurately reflect the number of rows displayed in
+ proportion to the number of rows in the dataset. If the driver
+ does not support the 'query size' property, rows are dynamically
+ fetched from the database on an as-needed basis with the scroll bar
+ becoming more accurate as the user scrolls down through the
+ records. This allows extremely large queries to be displayed as
+ quickly as possible, with minimum memory usage.
+
+ Q3DataTable inherits Q3Table's API and extends it with functions to
+ sort and filter the data and sort columns. See setSqlCursor(),
+ setFilter(), setSort(), setSorting(), sortColumn() and refresh().
+
+ When displaying editable cursors, cell editing will be enabled.
+ (For more information on editable cursors, see \l Q3SqlCursor).
+ Q3DataTable can be used to modify existing data and to add new
+ records. When a user makes changes to a field in the table, the
+ cursor's edit buffer is used. The table will not send changes in
+ the edit buffer to the database until the user moves to a
+ different record in the grid or presses Enter. Cell editing is
+ initiated by pressing F2 (or right clicking and then clicking the
+ appropriate popup menu item) and canceled by pressing Esc. If
+ there is a problem updating or adding data, errors are handled
+ automatically (see handleError() to change this behavior). Note
+ that if autoEdit() is false navigating to another record will
+ cancel the insert or update.
+
+ The user can be asked to confirm all edits with setConfirmEdits().
+ For more precise control use setConfirmInsert(),
+ setConfirmUpdate(), setConfirmDelete() and setConfirmCancels().
+ Use setAutoEdit() to control the behavior of the table when the
+ user edits a record and then navigates. (Note that setAutoDelete()
+ is unrelated; it is used to set whether the Q3SqlCursor is deleted
+ when the table is deleted.)
+
+ Since the data table can perform edits, it must be able to
+ uniquely identify every record so that edits are correctly
+ applied. Because of this the underlying cursor must have a valid
+ primary index to ensure that a unique record is inserted, updated
+ or deleted within the database otherwise the database may be
+ changed to an inconsistent state.
+
+ Q3DataTable creates editors using the default \l Q3SqlEditorFactory.
+ Different editor factories can be used by calling
+ installEditorFactory(). A property map is used to map between the
+ cell's value and the editor. You can use your own property map
+ with installPropertyMap().
+
+ The contents of a cell is available as a QString with text() or as
+ a QVariant with value(). The current record is returned by
+ currentRecord(). Use the find() function to search for a string in
+ the table.
+
+ Editing actions can be applied programmatically. For example, the
+ insertCurrent() function reads the fields from the current record
+ into the cursor and performs the insert. The updateCurrent() and
+ deleteCurrent() functions perform similarly to update and delete
+ the current record respectively.
+
+ Columns in the table can be created automatically based on the
+ cursor (see setSqlCursor()). Columns can be manipulated manually
+ using addColumn(), removeColumn() and setColumn().
+
+ The table automatically copies many of the properties of the
+ cursor to format the display of data within cells (alignment,
+ visibility, etc.). The cursor can be changed with setSqlCursor().
+ The filter (see setFilter()) and sort defined within the table are
+ used instead of the filter and sort set on the cursor. For sorting
+ options see setSort(), sortColumn(), sortAscending() and
+ sortDescending(). Note that sorting operations will not behave as
+ expected if you are using a QSqlSelectCursor because it uses
+ user-defined SQL queries to obtain data.
+
+ The text used to represent NULL, true and false values can be
+ changed with setNullText(), setTrueText() and setFalseText()
+ respectively. You can change the appearance of cells by
+ reimplementing paintField().
+
+ Whenever a new row is selected in the table the currentChanged()
+ signal is emitted. The primeInsert() signal is emitted when an
+ insert is initiated. The primeUpdate() and primeDelete() signals
+ are emitted when update and deletion are initiated respectively.
+ Just before the database is updated a signal is emitted;
+ beforeInsert(), beforeUpdate() or beforeDelete() as appropriate.
