The TQEditorFactory class is used to create editor widgets
for < a href = "ntqvariant.html" > TQVariant< / a > data types.
< p >
< p > Each editor factory provides the < a href = "#createEditor" > createEditor< / a > () function which
given a TQVariant will create and return a < a href = "tqwidget.html" > TQWidget< / a > that can edit
that TQVariant. For example if you have a TQVariant::String type, a
< a href = "tqlineedit.html" > TQLineEdit< / a > would be the default editor returned, whereas a
TQVariant::Int's default editor would be a < a href = "tqspinbox.html" > TQSpinBox< / a > .
< p > If you want to create different editors for fields with the same
data type, subclass TQEditorFactory and reimplement the
createEditor() function.
< p > See also < a href = "database.html" > Database Classes< / a > .

< h3 class = fn > < a name = "TQEditorFactory" > < / a > TQEditorFactory::TQEditorFactory ( < a href = "tqobject.html" > TQObject< / a > * parent = 0, const char * name = 0 )
< / h3 >
Constructs an editor factory with parent < em > parent< / em > , called < em > name< / em > .
< h3 class = fn > < a name = "~TQEditorFactory" > < / a > TQEditorFactory::~TQEditorFactory ()
< / h3 >
Destroys the object and frees any allocated resources.
< h3 class = fn > < a href = "tqwidget.html" > TQWidget< / a > * < a name = "createEditor" > < / a > TQEditorFactory::createEditor ( < a href = "tqwidget.html" > TQWidget< / a > * parent, const < a href = "ntqvariant.html" > TQVariant< / a > & v )< tt > [virtual]< / tt >
< / h3 >
Creates and returns the appropriate editor for the < a href = "ntqvariant.html" > TQVariant< / a > < em > v< / em > .
If the TQVariant is invalid, 0 is returned. The < em > parent< / em > is passed
to the appropriate editor's constructor.
< p > Reimplemented in < a href = "tqsqleditorfactory.html#createEditor" > TQSqlEditorFactory< / a > .
< h3 class = fn > < a href = "tqeditorfactory.html" > TQEditorFactory< / a > * < a name = "defaultFactory" > < / a > TQEditorFactory::defaultFactory ()< tt > [static]< / tt >
< / h3 >
Returns an instance of a default editor factory.
< h3 class = fn > void < a name = "installDefaultFactory" > < / a > TQEditorFactory::installDefaultFactory ( < a href = "tqeditorfactory.html" > TQEditorFactory< / a > * factory )< tt > [static]< / tt >
< / h3 >
Replaces the default editor factory with < em > factory< / em > .
< em > TQEditorFactory takes ownership of factory, and destroys it when it is no longer needed.< / em >
