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.

Member Function Documentation

TQEditorFactory::TQEditorFactory ( TQObject * parent = 0, const char * name = 0 )

Constructs an editor factory with parent parent, called name.

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]

Returns an instance of a default editor factory.

void TQEditorFactory::installDefaultFactory ( TQEditorFactory * factory ) [static]

Replaces the default editor factory with factory. TQEditorFactory takes ownership of factory, and destroys it when it is no longer needed.
