QHash ordered by value

[Lele]

Hi all,
I'd need to have a QHash where the elements are ordered by a certain filed inside the value.

struct MyData
	{
		MyData(): bitmap(0), weight(0)  {}
		MyData(qint64 b, qint32 w) : bitmap(b), weight(w) {}
 
		qint64 bitmap;
		qint32 weight;
	};
 
	QHash<qint32, MyData> mCurrentCache;

struct MyData
	{
		MyData(): bitmap(0), weight(0)  {}
		MyData(qint64 b, qint32 w) : bitmap(b), weight(w) {}

		qint64 bitmap;
		qint32 weight;
	};

	QHash<qint32, MyData> mCurrentCache;

To copy to clipboard, switch view to plain text mode 

In my case I would like to order the elements depending on MyData::weight.
Is there a smart way to do that or do I have to resort to an additional QHash<qint32, qint32> as a look up table?

Thanks for any help
bye
