--- Comment #10 from Tobias Doerffel tobias.doerffel@gmail.com --- Thanks for clarifying! Using Gtk is not an option for us (and actually we're quite satisfied with Qt ;-). As they dropped QX11Embed classes in Qt5 (and replaced it by a more generic approach in QWindow) I think it's the best solution to ship LMMS with a forked (and fixed) version of these classes. Would you mind helping us to fix the worst issues (e.g. the XEMBED_EMBEDDED_NOTIFY thing)?
