Hi Yuri,
I assume you're implementing a QSortFilterProxyModel for sorting and
filtering: you can reimplement QSortFilterProxyModel::lessThan()
<https://doc.qt.io/qt-5/qsortfilterproxymodel.html#lessThan>. Basically
you'll do the following (in pseudo code):
bool YourSortModel::lessThan(constQModelIndex <https://doc.qt.io/qt-5/qmodelindex.html>
&/source_left/, constQModelIndex <https://doc.qt.io/qt-5/qmodelindex.html>
&/source_right/)
{
auto left =/source_left.data(someRole);/
auto right=/source_right//.data(///someRole/);/
return (left.toByteArray() < right.toByteArray());
}
Mit freundlichen Grüßen | Kind regards,

Hi Thiago,
I am happy ro redesign my code, but how then sorting/filtering models
will work? As data() returns QVariant. Or you plan to use setSorting
based on lambda's and std::function to provide strict types sorting?
And what if from API point of view user want just to specify column
without aware of data types.
Am I missing something? Woukd really appreceate if you can point me to
some direction to look at.
Regards,
Yuri
Relational comparisons with QVariant are deprecated in 5.15 and will be
removed because they are a misfeaure. Redesign your code so your
question does
not need to be asked.
