isZipFile()

bool QgsZipUtils::isZipFile

(

const QString &

filename

)

Returns true if the file name is a zipped file ( i.e with a '.qgz' extension, false otherwise.

Parameters

filename

The name of the file

Returns

true if the file is zipped, false otherwise

Definition at line 32 of file qgsziputils.cpp.

unzip()

bool QgsZipUtils::unzip	(	const QString &	zip,
		const QString &	dir,
		QStringList &	files
	)

Unzip a zip file in an output directory.

Parameters

zip	The zip filename
dir	The output directory
files	The absolute path of unzipped files

Returns

false if the zip filename does not exist, the output directory does not exist or is not writable.

zip()

bool QgsZipUtils::zip	(	const QString &	zip,
		const QStringList &	files
	)

Zip the list of files in the zip file.

If the zip file already exists or is empty, an error is returned. If an input file does not exist, an error is also returned.

Parameters

zip	The zip filename
files	The absolute path to files to embed within the zip
