示例1: addError
void addError( PlugPtr plug, const std::string &error )
{
PlugEntry &entry = m_errors[plug];
entry.error = error;
if( !entry.parentChangedConnection.connected() )
{
entry.parentChangedConnection = plug->parentChangedSignal().connect( boost::bind( &ErrorGadget::parentChanged, this, ::_1 ) );
}
m_image->setVisible( true );
}示例2: addError
void addError( PlugPtr plug, const std::string &error )
{
PlugEntry &entry = m_errors[plug];
if( entry.error.empty() || !boost::ends_with( error, "Previous attempt to get item failed." ) )
{
// Update the error message. Unfortunately the IECore::LRUCache at the
// heart of Gaffer's caching does not remember the details of exceptions that
// occurred when the cache entry is in error - instead it throws a different
// exception saying "Previous attempt to get item failed.". We ignore these less
// helpful messages in favour of a previous messages if one exists.
/// \todo Improve LRUCache behaviour and remove this workaround.
entry.error = error;
