This works by +associating SQL editor class names to the properties used to +insert and extract values to/from the editor. +<p> For example, a <a href="qlineedit.html">QLineEdit</a> can be used to edit text strings and +other data types in QDataTables or QSqlForms. Several properties +are defined in QLineEdit, but only the <em>text</em> property is used to +insert and extract text from a QLineEdit. Both <a href="qdatatable.html">QDataTable</a> and +<a href="qsqlform.html">QSqlForm</a> use the global QSqlPropertyMap for inserting and +extracting values to and from an editor widget. The global +property map defines several common widgets and properties that +are suitable for many applications. You can add and remove widget +properties to suit your specific needs. +<p> If you want to use custom editors with your QDataTable or +QSqlForm, you must install your own QSqlPropertyMap for that table +or form. Example: +<p> <pre> + QSqlPropertyMap *myMap = new QSqlPropertyMap(); + <a href="qsqlform.html">QSqlForm</a> *myForm = new <a href="qsqlform.html">QSqlForm</a>( this ); + MyEditor myEditor( this ); + + // Set the QSqlForm's record buffer to the update buffer of + // a pre-existing QSqlCursor called 'cur'. + myForm-><a href="qsqlform.html#setRecord">setRecord</a>( cur->primeUpdate() ); + + // Install the customized map + myMap-><a href="#insert">insert</a>( "MyEditor", "content" ); + myForm-><a href="qsqlform.html#installPropertyMap">installPropertyMap</a>( myMap ); // myForm now owns myMap + ... + // Insert a field into the form that uses a myEditor to edit the + // field 'somefield' + myForm-><a href="qsqlform.html#insert">insert</a>( &myEditor, "somefield" ); + + // Update myEditor with the value from the mapped database field + myForm-><a href="qsqlform.html#readFields">readFields</a>(); + ... + // Let the user edit the form + ... + // Update the database fields with the values in the form + myForm-><a href="qsqlform.html#writeFields">writeFields</a>(); + ... + </pre> + +<p> You can also replace the global QSqlPropertyMap that is used by +default. (Bear in mind that QSqlPropertyMap takes ownership of the +new default map.) +<p> <pre> + QSqlPropertyMap *myMap = new QSqlPropertyMap; + + myMap-><a href="#insert">insert</a>( "MyEditor", "content" ); + QSqlPropertyMap::<a href="#installDefaultMap">installDefaultMap</a>( myMap ); + ... + </pre> + +<p> <p>See also <a href="qdatatable.html">QDataTable</a>, <a href="qsqlform.html">QSqlForm</a>, <a href="qsqleditorfactory.html">QSqlEditorFactory</a>, and <a href="database.html">Database Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QSqlPropertyMap"></a>QSqlPropertyMap::QSqlPropertyMap () +</h3> +<p> Constructs a QSqlPropertyMap. +<p> The default property mappings used by Qt widgets are: +<center><table cellpadding="4" cellspacing="2" border="0"> +<tr bgcolor="#a2c511"> <th valign="top">Widgets <th valign="top">Property +<tr bgcolor="#f0f0f0"> <td valign="top"><a href="qcheckbox.html">QCheckBox</a>, +<a href="qradiobutton.html">QRadioButton</a> +<td valign="top">checked +<tr bgcolor="#d0d0d0"> <td valign="top"><a href="qcombobox.html">QComboBox</a>, +<a href="qlistbox.html">QListBox</a> +<td valign="top">currentItem +<tr bgcolor="#f0f0f0"> <td valign="top"><a href="qdateedit.html">QDateEdit</a> +<td valign="top">date +<tr bgcolor="#d0d0d0"> <td valign="top"><a href="qdatetimeedit.html">QDateTimeEdit</a> +<td valign="top">dateTime +<tr bgcolor="#f0f0f0"> <td valign="top"><a href="qtextbrowser.html">QTextBrowser</a> +<td valign="top">source +<tr bgcolor="#d0d0d0"> <td valign="top"><a href="qbutton.html">QButton</a>, +<a href="qdial.html">QDial</a>, +<a href="qlabel.html">QLabel</a>, +<a href="qlineedit.html">QLineEdit</a>, +<a href="qmultilineedit.html">QMultiLineEdit</a>, +<a href="qpushbutton.html">QPushButton</a>, +<a href="qtextedit.html">QTextEdit</a>, +<td valign="top">text +<tr bgcolor="#f0f0f0"> <td valign="top"><a href="qtimeedit.html">QTimeEdit</a> +<td valign="top">time +<tr bgcolor="#d0d0d0"> <td valign="top"><a href="qlcdnumber.html">QLCDNumber</a>, +<a href="qscrollbar.html">QScrollBar</a> +<a href="qslider.html">QSlider</a>, +<a href="qspinbox.html">QSpinBox</a> +<td valign="top">value +</table></center> + +<h3 class=fn><a name="~QSqlPropertyMap"></a>QSqlPropertyMap::~QSqlPropertyMap ()<tt> [virtual]</tt> +</h3> +Destroys the QSqlPropertyMap. +<p> Note that if the QSqlPropertyMap is installed with +installPropertyMap() the object it was installed into, e.g. the +<a href="qsqlform.html">QSqlForm</a>, takes ownership and will delete the QSqlPropertyMap when +necessary. + +<h3 class=fn><a href="qsqlpropertymap.html">QSqlPropertyMap</a> * <a name="defaultMap"></a>QSqlPropertyMap::defaultMap ()<tt> [static]</tt> +</h3> +Returns the application global QSqlPropertyMap. + +<h3 class=fn>void <a name="insert"></a>QSqlPropertyMap::insert ( const <a href="qstring.html">QString</a> & classname, const <a href="qstring.html">QString</a> & property ) +</h3> +Insert a new classname/property pair, which is used for custom SQL +field editors.
