Qt Wayland multi-process, can't acquire inputMethodHints of QWaylandQuickShellSurfaceItem's focused input

umed

Hey there,

I'm using wayland compositor in multi-process mode.

I want my compositor to access inputMethodHints of another process's focused input (i.e. TextInput).
Within compositor I've got focused QWaylandQuickShellSurfaceItem of that process.

To achieve that I'm doing following:

QInputMethodQueryEvent imQueryEvent(Qt::InputMethodQueries(Qt::ImHints));
QGuiApplication::sendEvent(waylandShellSurface, &imQueryEvent);
auto inputMethodHints = Qt::InputMethodHints(imQueryEvent.value(Qt::ImHints).toInt());

But as it turns out, imQueryEvent event hasn't been sent over wayland protocol, so my inputMethodHints is always equal to QFlags<Qt::InputMethodHint>(ImhNone).
Is there any other way to request focused input of QWaylandQuickShellSurfaceItem or to fix behavior of QGuiApplication::sendEvent to achieve that?
