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