Member Function Documentation


Constructs a QSafeBitmapResourceReader object.

[override virtual] const SafeRenderer::QSafeBitmap *QSafeBitmapResourceReader::getBitmapByID(const SafeRenderer::quint32 hash) const

Reimplements: QSafeBitmapReader::getBitmapByID(const SafeRenderer::quint32 hash) const.

Returns a pointer to the QSafeBitmap item. The hash value is the hash value of the bitmap file name. The hash can be calculated with qt_hash function.

[override virtual] void QSafeBitmapResourceReader::loadBitmapFile(const SafeRenderer::qchar *const file, const SafeRenderer::quint32 crc)

Reimplements: QSafeBitmapReader::loadBitmapFile(const SafeRenderer::qchar *const file, const SafeRenderer::quint32 crc).

Loads the bitmap file from the Qt resource data structure. The crc is ignored.
