Hi guys, I'm really stuck with this.
Can anyone help? ---------- Forwarded message --------- Van: Ralf Van Bogaert <ralf.vanboga...@gmail.com> Date: wo 1 jun. 2022 om 16:15 Subject: QWaylandCompositor question To: <interest@qt-project.org> Hello, I am developing a Qt-based desktop environment, and would like to use QWaylandCompositor to provide built-in compositing. I am looking at several QML-based examples like Pure QML <https://code.qt.io/cgit/qt/qtwayland.git/tree/examples/wayland/pure-qml?h=5.15>, but I would like to implement it using the C++ classes only. So I've rewritten it to the best of my ability, and it actually works - application windows show up in the compositor - except that they do not update their content. Applications do respond to clicks, and even show popup menus - but it's hard to tell since the window's content does not show any feedback. These same applications work fine in the Pure QML example. The problem is (I suspect) I am not handling the QWaylandXdgShell::toplevelCreated(QWaylandXdgToplevel*,QWaylandXdgSurface*) signal correctly. Currently the slot it connects to looks like this: void Compositor::onToplevelCreated(QWaylandXdgToplevel *toplevel,QWaylandXdgSurface *xdgSurface) { QQuickWindow *outputWindow=static_cast<QQuickWIndow*>(defaultOutput()->window()); QWaylandQuickShellSurfaceItem item(outputWindow->contentItem()); item->setShellSurface(xdgSurface); } It is unclear to me how the QML version handles this, since this functionality is hidden under all that nice syntactic sugar. Is anyone able to help? Regards Ralf
