Member Function Documentation

◆ addFileImport()

QTypeRevision QQmlImports::addFileImport	(	QQmlImportDatabase *	database,
		const QString &	uri,
		const QString &	prefix,
		QTypeRevision	version,
		ImportFlags	flags,
		quint16	precedence,
		QString *	localQmldir,
		QList< QQmlError > *	errors
	)

Adds information to database such that subsequent calls to resolveType() will resolve types qualified by prefix by considering types found at the given uri.

The uri is either a directory (if importType is FileImport), or a URI resolved using paths added via addImportPath() (if importType is LibraryImport).

The prefix may be empty, in which case the import location is considered for unqualified types.

The base URL must already have been set with Import::setBaseUrl().

Optionally, the qmldir the import resolved to can be returned by providing the localQmldir parameter. Not all imports will have a local qmldir. If there is none, the localQmldir parameter won't be set.

Returns a valid QTypeRevision on success, and an invalid one on failure. In case of failure, the errors array will filled appropriately.

◆ addImplicitImport()

QQmlImports::addImplicitImport	(	QQmlImportDatabase *	importDb,
		QString *	localQmldir,
		QList< QQmlError > *	errors
	)

inline

Adds an implicit "." file import. This is equivalent to calling addFileImport(), but error messages related to the path or qmldir file not existing are suppressed.

Additionally, this will add the import with lowest instead of highest precedence.
