Detailed Description

The QSupportedWritingSystems class is used when registering fonts with the internal Qt fontdatabase.

Since

4.8

Its to provide an easy to use interface for indicating what writing systems a specific font supports.

setSupported()

void QSupportedWritingSystems::setSupported	(	QFontDatabase::WritingSystem	writingSystem,
		bool	support = true
	)

Sets the supported state of the writing system given by writingSystem to the value specified by support.

A value of true indicates that the writing system is supported; a value of false indicates that it is unsupported.
