<hr><a name="details"></a><h2>Detailed Description</h2>





<p> The QDataTable class provides a flexible SQL table widget that supports browsing and editing.
<p> QDataTable supports various functions for presenting and editing SQL
data from a <a href="qsqlcursor.html">QSqlCursor</a> in a table.
<p> If you want a to present your data in a form use <a href="qdatabrowser.html">QDataBrowser</a>, or
for read-only forms, <a href="qdataview.html">QDataView</a>.
<p> When displaying data, QDataTable only retrieves data for visible rows.
If the driver supports the 'query size' property the QDataTable will
have the correct number of rows and the vertical scrollbar 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 scrollbar 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.
<p> QDataTable inherits <a href="qtable.html">QTable</a>'s API and extends it with functions to
sort and filter the data and sort columns. See <a href="#setSqlCursor">setSqlCursor</a>(),
<a href="#setFilter">setFilter</a>(), <a href="#setSort">setSort</a>(), <a href="qtable.html#setSorting">setSorting</a>(), <a href="#sortColumn">sortColumn</a>() and <a href="#refresh">refresh</a>().
<p> When displaying editable cursors, cell editing will be enabled. (For
more information on editable cursors, see <a href="qsqlcursor.html">QSqlCursor</a>).  QDataTable
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 Return. Cell editing is initiated by pressing F2 (or right
clicking and then clicking the appropriate popup menu item) and
cancelled by pressing Esc. If there is a problem updating or adding
data, errors are handled automatically (see <a href="#handleError">handleError</a>() to change
this behavior). Note that if <a href="#autoEdit">autoEdit</a>() is FALSE navigating to another
record will cancel the insert or update.
<p> The user can be asked to confirm all edits with <a href="#setConfirmEdits">setConfirmEdits</a>().
For more precise control use <a href="#setConfirmInsert">setConfirmInsert</a>(), <a href="#setConfirmUpdate">setConfirmUpdate</a>(),
<a href="#setConfirmDelete">setConfirmDelete</a>() and <a href="#setConfirmCancels">setConfirmCancels</a>(). Use <a href="#setAutoEdit">setAutoEdit</a>() to
control the behaviour of the table when the user edits a record and
then navigates. (Note that <a href="#setAutoDelete">setAutoDelete</a>() is unrelated; it is used
to set whether the <a href="qsqlcursor.html">QSqlCursor</a> is deleted when the table is deleted.)
<p> 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.
<p> QDataTable creates editors using the default <a href="qsqleditorfactory.html">QSqlEditorFactory</a>.
Different editor factories can be used by calling
<a href="#installEditorFactory">installEditorFactory</a>(). A property map is used to map between the
cell's value and the editor. You can use your own property map with
<a href="#installPropertyMap">installPropertyMap</a>().
<p> The contents of a cell is available as a <a href="qstring.html">QString</a> with <a href="#text">text</a>() or as a
<a href="qvariant.html">QVariant</a> with <a href="#value">value</a>(). The current record is returned by
<a href="#currentRecord">currentRecord</a>(). Use the <a href="#find">find</a>() function to search for a string in
the table.
<p> Editing actions can be applied programatically. For example, the
<a href="#insertCurrent">insertCurrent</a>() function reads the fields from the current record
into the cursor and performs the insert. The <a href="#updateCurrent">updateCurrent</a>() and
<a href="#deleteCurrent">deleteCurrent</a>() functions perform similarly to update and delete the
current record respectively.
<p> Columns in the table can be created automatically based on the
cursor (see <a href="#setSqlCursor">setSqlCursor</a>()). Columns can be manipulated manually using
<a href="#addColumn">addColumn</a>(), <a href="#removeColumn">removeColumn</a>() and <a href="#setColumn">setColumn</a>().
<p> 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 <a href="#setFilter">setFilter</a>()) and sort defined within the table
are used instead of the filter and sort set on the cursor. For sorting
options see <a href="#setSort">setSort</a>(), <a href="#sortColumn">sortColumn</a>(), <a href="#sortAscending">sortAscending</a>() and
<a href="#sortDescending">sortDescending</a>().
<p> The text used to represent NULL, TRUE and FALSE values can be
changed with <a href="#setNullText">setNullText</a>(), <a href="#setTrueText">setTrueText</a>() and <a href="#setFalseText">setFalseText</a>()
respectively. You can change the appearance of cells by
reimplementing <a href="#paintField">paintField</a>().
<p> Whenever a new row is selected in the table the <a href="#currentChanged">currentChanged</a>()
signal is emitted. The <a href="#primeInsert">primeInsert</a>() signal is emitted when an
insert is initiated. The <a href="#primeUpdate">primeUpdate</a>() and <a href="#primeDelete">primeDelete</a>() signals are
emitted when update and deletion are initiated respectively. Just
before the database is updated a signal is emitted; <a href="#beforeInsert">beforeInsert</a>(),
<a href="#beforeUpdate">beforeUpdate</a>() or <a href="#beforeDelete">beforeDelete</a>() as appropriate.

<hr><h2>Member Type Documentation</h2>
<h3 class=fn><a name="Refresh-enum"></a>QDataTable::Refresh</h3> 
<p> This enum describes the refresh options.
<p> The currently defined values are:
<ul>
<li><tt>QDataTable::RefreshData</tt> - refresh the data, i.e. read it from the database
<li><tt>QDataTable::RefreshColumns</tt> - refresh the list of fields, e.g. the column headings
<li><tt>QDataTable::RefreshAll</tt> - refresh both the data and the list of fields
</ul>
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QDataTable"></a>QDataTable::QDataTable ( <a href="qwidget.html">QWidget</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;name = 0 )
</h3> Constructs a data table which is a child of <em>parent</em>, with the
name <em>name</em>.
<p> 
<h3 class=fn><a name="QDataTable-2"></a>QDataTable::QDataTable ( <a href="qsqlcursor.html">QSqlCursor</a>&nbsp;*&nbsp;cursor, bool&nbsp;autoPopulate = FALSE, <a href="qwidget.html">QWidget</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;name = 0 )
</h3>  Constructs a data table which is a child of <em>parent</em>, with the
name <em>name</em> using the cursor <em>cursor</em>.
<p> If <em>autoPopulate</em> is TRUE (the default is FALSE), columns are
automatically created based upon the fields in the <em>cursor</em> record.
Note that <em>autoPopulate</em> only governs the creation of columns; to
load the cursor's data into the table use <a href="#refresh">refresh</a>().
<p> If the <em>cursor</em> is read-only, the table also becomes read-only.  In
addition, the table adopts the cursor's driver's definition for
representing NULL values as strings.

<h3 class=fn><a name="~QDataTable"></a>QDataTable::~QDataTable ()
</h3> Destroys the object and frees any allocated resources.
<p> 
<h3 class=fn>void <a name="addColumn"></a>QDataTable::addColumn ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;fieldName, const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;label = QString::null, int&nbsp;width = -1, const&nbsp;<a href="qiconset.html">QIconSet</a>&nbsp;&amp;&nbsp;iconset = QIconSet ( ) )<tt> [virtual]</tt>
</h3>  Adds the next column to be displayed using the field <em>fieldName</em>, column label <em>label</em>, width <em>width</em> and iconset <em>iconset</em>.
<p> If <em>label</em> is specified, it is used as the column's header label,
otherwise the field's display label is used when <a href="#setSqlCursor">setSqlCursor</a>() is
called. The <em>iconset</em> is used to set the icon used by the column
header; by default there is no icon.
<p> <p>See also <a href="#setSqlCursor">setSqlCursor</a>() and <a href="#refresh">refresh</a>().

<p> 
<p>Examples: <a href="sql.html#x2369">sql/overview/subclass1/main.cpp</a>, <a href="sql.html#x2372">sql/overview/subclass3/main.cpp</a>, <a href="sql.html#x2328">sql/overview/table2/main.cpp</a> and <a href="sqltable-example.html#x2633">sql/sqltable/main.cpp</a>.
<h3 class=fn>bool <a name="autoDelete"></a>QDataTable::autoDelete () const
</h3> Returns TRUE if the table will automatically delete the cursor
specified by <a href="#setSqlCursor">setSqlCursor</a>(), otherwise returns FALSE.

<h3 class=fn>bool <a name="autoEdit"></a>QDataTable::autoEdit () const
</h3><p>Returns TRUE if the data table automatically applies edits; otherwise returns FALSE.
See the <a href="qdatatable.html#autoEdit-prop">"autoEdit"</a> property for details.
<h3 class=fn>void <a name="beforeDelete"></a>QDataTable::beforeDelete ( <a href="qsqlrecord.html">QSqlRecord</a>&nbsp;*&nbsp;buf )<tt> [signal]</tt>
</h3> 
This signal is emitted just before the currently selected record is
deleted from the database. The <em>buf</em> parameter points to the edit
buffer being deleted. Connect to this signal to, for example, copy
some of the fields for later use.
<p> 
<h3 class=fn>void <a name="beforeInsert"></a>QDataTable::beforeInsert ( <a href="qsqlrecord.html">QSqlRecord</a>&nbsp;*&nbsp;buf )<tt> [signal]</tt>
</h3> 
This signal is emitted just before the cursor's edit buffer is
inserted into the database. The <em>buf</em> parameter points to the edit
buffer being inserted. Connect to this signal to, for example,
populate a key field with a unique sequence number.

<h3 class=fn>void <a name="beforeUpdate"></a>QDataTable::beforeUpdate ( <a href="qsqlrecord.html">QSqlRecord</a>&nbsp;*&nbsp;buf )<tt> [signal]</tt>
</h3> 
This signal is emitted just before the cursor's edit buffer is updated
in the database. The <em>buf</em> parameter points to the edit buffer being
updated. Connect to this signal when you want to transform
the user's data behind-the-scenes.

<h3 class=fn>bool <a name="beginInsert"></a>QDataTable::beginInsert ()<tt> [virtual protected]</tt>
</h3> Protected virtual function called when editing is about to begin on
a new record.  If the table is read-only, or if there's no cursor or
the cursor does not allow inserts, nothing happens.
<p> Editing takes place using the cursor's edit buffer(see
<a href="qsqlcursor.html#editBuffer">QSqlCursor::editBuffer</a>()).
<p> When editing begins, a new row is created in the table marked with
an asterisk '*' in the row's vertical header column, i.e. at the left
of the row.
<p> 
<h3 class=fn><a href="qwidget.html">QWidget</a>&nbsp;* <a name="beginUpdate"></a>QDataTable::beginUpdate ( int&nbsp;row, int&nbsp;col, bool&nbsp;replace )<tt> [virtual protected]</tt>
</h3> Protected virtual function called when editing is about to begin on
an existing row.  If the table is read-only, or if there's no cursor,
nothing happens.
<p> Editing takes place using the cursor's edit buffer (see
<a href="qsqlcursor.html#editBuffer">QSqlCursor::editBuffer</a>()).
<p> <em>row</em> and <em>col</em> refer to the row and column in the QDataTable.
<p> (<em>replace</em> is provided for reimplementors and reflects the API of
<a href="qtable.html#beginEdit">QTable::beginEdit</a>().)
<p> 
<h3 class=fn><a href="qsql.html#Confirm-enum">QSql::Confirm</a> <a name="confirmCancel"></a>QDataTable::confirmCancel ( <a href="qsql.html#Op-enum">QSql::Op</a>&nbsp;m )<tt> [virtual protected]</tt>
</h3>  Protected virtual function which returns a confirmation for
cancelling an edit mode of <em>m</em>.  Derived classes can reimplement
this function to provide their own cancel dialog.  The default
implementation uses a message box which prompts the user to confirm
the cancel.
<p> 
<h3 class=fn>bool <a name="confirmCancels"></a>QDataTable::confirmCancels () const

<p>The table's sort affects the order in which data records are displayed
in the table.  To apply a sort, use <a href="#refresh">refresh</a>().
<p> When examining the sort property, a string list is returned with each
item having the form 'fieldname order' (e.g., 'id ASC', 'surname DESC').
<p> There is no default sort.
<p> Note that if you want to iterate over the sort list, you should
iterate over a copy, e.g.
<pre>
    <a href="qstringlist.html">QStringList</a> list = myDataTable.sort();
    QStringList::Iterator it = list.<a href="qvaluelist.html#begin">begin</a>();
    while( it != list.<a href="qvaluelist.html#end">end</a>() ) {
        myProcessing( *it );
        ++it;
    }
    </pre>
