addExtensionFromFilter()

QString QgsFileUtils::addExtensionFromFilter ( const QString &  fileName, const QString &  filter  )

static

Ensures that a fileName ends with an extension from the specified filter string.

E.g. a fileName of "d:/my_file" with a filter of "GeoTIFF Files (*.tiff *.tif)" will return "d:/my_file.tif", where as fileName of "d:/my_file.TIFF" or "d:/my_file.TIF" will be returned unchanged.

ensureFileNameHasExtension()

QString QgsFileUtils::ensureFileNameHasExtension ( const QString &  fileName, const QStringList &  extensions  )

static

Ensures that a fileName ends with an extension from the provided list of extensions.

E.g. if extensions contains "tif" and "tiff", then a fileName of "d:/my_file" will return "d:/my_file.tif". A fileName of "d:/my_file.TIFF" or "d:/my_file.TIF" will be returned unchanged.

extensionsFromFilter()

QStringList QgsFileUtils::extensionsFromFilter ( const QString &  filter )

static

Returns a list of the extensions contained within a file filter string.

E.g. a filter of "GeoTIFF Files (*.tiff *.tif)" would return a list containing "tiff", "tif". The initial '.' is stripped off the extension.

representFileSize()

QString QgsFileUtils::representFileSize ( qint64  bytes )

static

Returns the human size from bytes.

Definition at line 19 of file qgsfileutils.cpp.

stringToSafeFilename()

QString QgsFileUtils::stringToSafeFilename ( const QString &  string )

static

Converts a string to a safe filename, replacing characters which are not safe for filenames with an '_' character.

Warning

This method strips slashes from the filename, so it is safe to call with file names only, not complete paths.
