@innermous There are two other places where QByteArray() are used, which might need changing too:

• https://github.com/sqlitebrowser/sqlitebrowser/blob/master/src/EditDialog.cpp#L44
• https://github.com/sqlitebrowser/sqlitebrowser/blob/master/src/EditDialog.cpp#L149

I don't really grok the difference (yet), so am unsure. What do you think?

So, I tried setting those other two lines to QVariant(), to see what would happen.

The build barfs complaining there's no valid conversion type. QHexEdit::setData() really wants a QByteArray() for those two. 😄

With the one changed in this PR, it's a different setData(). This one is QAbstractItemModel::setData(), which prefers QVariant().

With the aid of F2 in Qt Creator (to show the definition under the cursor), I think I'm learning. 😉

Thanks for pointing this out @innermous. 😄
