Detailed Description
The TQEditorFactory class is used to create editor widgets
for TQVariant data types.
Each editor factory provides the createEditor() function which
given a TQVariant will create and return a TQWidget that can edit
that TQVariant. For example if you have a TQVariant::String type, a
TQLineEdit would be the default editor returned, 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 TQEditorFactory and reimplement the
createEditor() function.

TQEditorFactory::~TQEditorFactory ()
Destroys the object and frees any allocated resources.
TQWidget * TQEditorFactory::createEditor ( TQWidget * parent, const TQVariant & v ) [virtual]
Creates and returns the appropriate editor for the TQVariant v.
If the TQVariant is invalid, 0 is returned. The parent is passed
to the appropriate editor's constructor.
Reimplemented in TQSqlEditorFactory.
TQEditorFactory * TQEditorFactory::defaultFactory () [static]
