.SH DESCRIPTION
The TQSqlEditorFactory class is used to create the editors used by TQDataTable and TQSqlForm.
.PP
TQSqlEditorFactory is used by TQDataTable and TQSqlForm to automatically create appropriate editors for a given TQSqlField. For example if the field is a QVariant::String a QLineEdit would be the default editor, whereas a QVariant::Int's default editor would be a QSpinBox.
.PP
If you want to create different editors for fields with the same data type, subclass TQSqlEditorFactory and reimplement the createEditor() function.
.PP
See also TQDataTable, TQSqlForm, and Database Classes.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "TQSqlEditorFactory::TQSqlEditorFactory ( TQObject * parent = 0, const char * name = 0 )"
Constructs a SQL editor factory with parent \fIparent\fR, called \fIname\fR.
.SH "TQSqlEditorFactory::~TQSqlEditorFactory ()"
Destroys the object and frees any allocated resources.
.SH "TQWidget * TQSqlEditorFactory::createEditor ( TQWidget * parent, const QVariant & variant )\fC [virtual]\fR"
Creates and returns the appropriate editor widget for the QVariant \fIvariant\fR.
.PP
The widget that is returned has the parent \fIparent\fR (which may be zero). If \fIvariant\fR is invalid, 0 is returned.
.PP
Reimplemented from TQEditorFactory.
.SH "TQWidget * TQSqlEditorFactory::createEditor ( TQWidget * parent, const TQSqlField * field )\fC [virtual]\fR"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Creates and returns the appropriate editor for the TQSqlField \fIfield\fR.
.SH "TQSqlEditorFactory * TQSqlEditorFactory::defaultFactory ()\fC [static]\fR"
Returns an instance of a default editor factory.
.SH "void TQSqlEditorFactory::installDefaultFactory ( TQSqlEditorFactory * factory )\fC [static]\fR"
Replaces the default editor factory with \fIfactory\fR. All
TQDataTable and TQSqlForm instantiations will use this new factory
for creating field editors. \fIQSqlEditorFactory takes ownership of &#92;a factory, and destroys it when it is no longer needed.\fR
