Member Function Documentation

QSafeLayoutFileReader::QSafeLayoutFileReader(const SafeRenderer::qchar *const filenameArg)

Constructs a safe layout file reader that reads the layout data from the 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, one of the following exceptions are thrown:

SafeRenderer::QSafeBitmapFileReader::BitmapFileReaderException::TooManyThe number of bitmaps exceeds the Constraints::MAX_AMOUNT_OF_BITMAPS value.
SafeRenderer::QSafeFile::FileException::SeekErrorSeek 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::QSafeLayout::LayoutException::DataSizeMismatchLayout file's size is more than buffer's size.
SafeRenderer::QSafeFile::FileException::ReadErrorThe requested number of bytes can not be read from the opened file.
SafeRenderer::QSafeLayout::LayoutException::SizeErrorWidthThe width of the layout size too long.
SafeRenderer::QSafeLayout::LayoutException::SizeErrorHeightThe height of the layout size too long.
SafeRenderer::QSafeLayout::LayoutException::DataSizeMismatchThe layout file size is not multiple of the layout data size or layout data size is too small, or has too many layouts
SafeRenderer::QSafeLayout::LayoutException::InvalidLayoutVersionLayout version is not supported.
SafeRenderer::QSafeLayout::LayoutException::CheckSumFailedLayout checksum value does not match with the data checksum.
SafeRenderer::QSafeLayout::LayoutException::TooLongFilenameBitmap's filename was too long to fit in buffer.
