.SH DESCRIPTION
|
|
The QSqlEditorFactory class is used to create the editors used by QDataTable and QSqlForm.
|
|
.PP
|
|
QSqlEditorFactory is used by QDataTable and QSqlForm to automatically create appropriate editors for a given QSqlField. 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 QSqlEditorFactory and reimplement the createEditor() function.
|
|
.PP
|
|
See also QDataTable, QSqlForm, and Database Classes.
|
|
.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "QSqlEditorFactory::QSqlEditorFactory ( QObject * parent = 0, const char * name = 0 )"
|
|
Constructs a SQL editor factory with parent \fIparent\fR, called \fIname\fR.
|
|
.SH "QSqlEditorFactory::~QSqlEditorFactory ()"
|
|
Destroys the object and frees any allocated resources.
|
|
.SH "QWidget * QSqlEditorFactory::createEditor ( QWidget * 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 QEditorFactory.
|
|
.SH "QWidget * QSqlEditorFactory::createEditor ( QWidget * parent, const QSqlField * 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 QSqlField \fIfield\fR.
|
|
.SH "QSqlEditorFactory * QSqlEditorFactory::defaultFactory ()\fC [static]\fR"
|
|
Returns an instance of a default editor factory.
|
|
.SH "void QSqlEditorFactory::installDefaultFactory ( QSqlEditorFactory * factory )\fC [static]\fR"
|
|
Replaces the default editor factory with \fIfactory\fR. All
|
|
QDataTable and QSqlForm instantiations will use this new factory
|
|
for creating field editors. \fIQSqlEditorFactory takes ownership of \a factory, and destroys it when it is no longer needed.\fR
