Member Function Documentation
ResourceMap::ResourceMap(QObject *parent = nullptr)
Constructs with the given parent object.
QString ResourceMap::errorString() const
Returns an user readable description of the last error occurred.
The error string may be set by the updateMapping() call.
LiveDocument ResourceMap::toDocument(const QString &resource) const
Returns the document that maps to the given resource or a null LiveDocument if no corresponding mapping exists.
This is a low level API. LiveDocument provides more convenient API.
QString ResourceMap::toResource(const LiveDocument &document) const
Returns the resource that maps to the given document or an empty QString if no corresponding mapping exists.
This is a low level API. LiveDocument provides more convenient API.
bool ResourceMap::updateMapping(const LiveDocument &qrcDocument, QIODevice *qrcFile)
Updates mapping from the given .qrc document
Old mappings for the given qrcDocument will be removed, then new mappings will be added based on the content of the qrcFile.
Returns true on success. Otherwise errorString() is set and false returned.
