Member Function Documentation

QSafeLayoutFileReader::QSafeLayoutFileReader()

Constructs a safe layout file reader.

`[override virtual, since QtSafeRenderer 1.1]` const SafeRenderer::QSafeByteArray QSafeLayoutFileReader::readDataFromFile(const SafeRenderer::qchar const filenameArg*)

Reimplements: QSafeLayout::readDataFromFile(const SafeRenderer::qchar *const filenameArg).

Read file with filenameArg. Returns the pointer to the read data.

This function was introduced in QtSafeRenderer 1.1.

`[override virtual, since QtSafeRenderer 3.0]` void QSafeLayoutFileReader::readLayout(const SafeRenderer::qchar const filenameArg*)

Reads the layout data from the given file filenameArg.

The full path of the file can given to the filenameArg parameter. The bitmap data files must be located in the same path with the layout data file.

In case of a failure, an exception will be thrown:

Exception	Id	Description
SafeRenderer::QSafeLayoutException	SafeRenderer::QSafeLayoutException::LayoutException::InvalidFilename	Filename was not provided.
SafeRenderer::QSafeBitmapException	SafeRenderer::QSafeBitmapException::BitmapException::TooMany	The number of bitmaps exceeds the Constraints::MAX_AMOUNT_OF_BITMAPS value.
SafeRenderer::QSafeFileException	SafeRenderer::QSafeFileException::FileException::SeekError	Seek failed on opening the file. For example, the root cause for the error can be a filesystem error or a file that is a pipe.
SafeRenderer::QSafeLayoutException	SafeRenderer::QSafeLayoutException::LayoutException::DataSizeMismatch	Layout file's size is more than buffer's size.
SafeRenderer::QSafeFileException	SafeRenderer::QSafeFileException::FileException::ReadError	The requested number of bytes can not be read from the opened file.
SafeRenderer::QSafeLayoutException	SafeRenderer::QSafeLayoutException::LayoutException::SizeErrorWidth	The width of the layout size too long.
SafeRenderer::QSafeLayoutException	SafeRenderer::QSafeLayoutException::LayoutException::SizeErrorHeight	The height of the layout size too long.
SafeRenderer::QSafeLayoutException	SafeRenderer::QSafeLayoutException::LayoutException::DataSizeMismatch	The layout file size is not multiple of the layout data size or layout data size is too small, or has too many layouts.
SafeRenderer::QSafeLayoutException	SafeRenderer::QSafeLayoutException::LayoutException::InvalidLayoutVersion	Layout version is not supported.
SafeRenderer::QSafeLayoutException	SafeRenderer::QSafeLayoutException::LayoutException::CheckSumFailed	Layout checksum value does not match with the data checksum.
SafeRenderer::QSafeLayoutException	SafeRenderer::QSafeLayoutException::LayoutException::TooLongFilename	Bitmap's filename was too long to fit in buffer.

This function was introduced in QtSafeRenderer 3.0.
