virtual bool iimg::CBitmapLoaderComp::GetFileExtensions ( QStringList &  result,
const istd::IChangeable dataObjectPtr = NULL,
int  flags = -1,
bool  doAppend = false 
) const
virtual

Get file extensions supported by this loader.

Parameters
resultlist of extensions, e.g. {"txt", "doc"}.
dataObjectPtroptional pointer to data object for which all possible extensions are requested. It can be NULL if any object is meant.
flagsset of flags
See Also
QueryFlags.
Parameters
doAppendif true, list of extensions should be appended to existing list.

Implements ifile::IFileTypeInfo.

virtual QString iimg::CBitmapLoaderComp::GetTypeDescription ( const QString *  extensionPtr = NULL) const
virtual

Get description of object type associated with single extension.

Implements ifile::IFileTypeInfo.

virtual bool iimg::CBitmapLoaderComp::IsOperationSupported ( const istd::IChangeable dataObjectPtr,
const QString *  filePathPtr = NULL,
int  flags = -1,
bool  beQuiet = true 
) const
virtual

Returns true if object dataObject can be loaded/saved.

Parameters
dataObjectPtroptional pointer to data object should be loaded/stored. It can be NULL if any object is meant.
filePathPtroptional pointer to file should be loaded/stored. It can be NULL if any file is meant. If it points at empty string, anonymous loading is mean.
flagscombination of flags defined in QueryFlags and ifile::IFileTypeInfo::QueryFlags.
beQuietif true, no user message output is allowed.

Implements ifile::IFilePersistence.
