I don't know about sqlite, but in derby I use byte[] to save image with a blob
field. I'm using this method to convert QImage to byte[].
public byte[] getImageBytes(QImage image) {
QByteArray ba = new QByteArray();
QBuffer buffer = new QBuffer(ba);
buffer.open(OpenModeFlag.WriteOnly);
if (image != null) {
image.save(buffer, "JPG");
image = null;
}
byte[] returnbyteArray = ba.toByteArray();
return returnbyteArray;
}
I thing that cause less troubles than using QByteArray.
If you are curious, I'm using eclipseLink for the persistence management
instead of QtSql.
