Detailed Description

The QFontEnginePlugin class is the base class for font engine factory plugins in Qt for Embedded Linux.

This function is under development and subject to change.

Since
4.3

QFontEnginePlugin is provided by font engine plugins to create instances of subclasses of QAbstractFontEngine.

The member functions create() and availableFontEngines() must be implemented.

Functions

◆ availableFontEngines()

QList< QFontEngineInfo > QFontEnginePlugin::availableFontEngines ( ) const
pure virtual

Implemented in subclasses to return a list of QFontEngineInfo objects that represents all font engines the plugin can create.

Implements QFontEngineFactoryInterface.

◆ create()

QAbstractFontEngine * QFontEnginePlugin::create ( const QFontEngineInfo info)
pure virtual

Implemented in subclasses to create a new font engine that provides a font that matches info.

Implements QFontEngineFactoryInterface.

◆ keys()

QStringList QFontEnginePlugin::keys ( ) const
virtual

Returns a list of foundries the font engine plugin provides.

The default implementation returns the foundry specified with the constructor.

Implements QFactoryInterface.
