Qt5 to Qt6 porting

Dariusz

Hey!

Sooo the time has come to port to Qt6... so how can I find functions/replacement functions for this mamoth task ?

Atm I'm in QTreeView and viewOptions() option is now gone with no hint to what has replaced it...

Can any1 hint me to how can I approach this task ?

Is there any documentation that explains what was removed/replaced/how to handle new api ?

TIA

It doesn't appear to have made it into the Qt 6 widgets changes documentation at https://doc.qt.io/qt-6/widgets-changes-qt6.html.

I used something like this:

QStyleOptionViewItem option;
#if QT_VERSION >= QT_VERSION_CHECK(6, 0, 0)
initViewItemOption(&option);
#else
option = viewOptions();
#endif

Compile your program with Qt5.15, fix all deprecation warnings and it will properly compile with Qt6.

@Jonas-Kvinge thanks! That looks good. Will work off that!

@Christian-Ehrlicher Yeh my bad I was on 5.15.1 or something like that, but I must have missed that warning.

All good danke all!

In this case I was wrong since the new virtual function could not be added to 5.15 since this would break binary compatibility. There was only a changelog entry for it: https://codereview.qt-project.org/c/qt/qtbase/+/310416

A section to this change will be added in the next Qt6 version: https://codereview.qt-project.org/c/qt/qtbase/+/341841
Thx for the hint.
