The launched KWin instance connects to your Wayland server, binds to the Shell and will create a ShellSurface. That you will get through a signal on m_shell - compare wayland_server.cpp:148. I would as a next step try to hook into this and see whether the surface gets created. Once you have that you can look into rendering it.</p>
<p>For that the ShellSurfaceInterface is connected to a SurfaceInterface. The rendering happens on the SurfaceInterface. There's a damaged signal which you should use to trigger a repaint of your QQuickItem. When rendering you can access the buffer on the SurfaceInterface. If KWin uses KWIN_COMPOSE=Q you can access the buffer as a QImage and just render it. Pretty straight forward - hopefully. But first try to see whether you get the ShellSurface created. If not we need to look into what goes wrong.</p></div>

<p>I've added the slot for checking if surface gets created but signal doesn't get emitted. Would you please show me the way to proceed further now.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>rKWIN KWin</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D1989" rel="noreferrer">https://phabricator.kde.org/D1989</a></div></div><br /><div><strong>EMAIL PREFERENCES</strong><div><a href="https://phabricator.kde.org/settings/panel/emailpreferences/" rel="noreferrer">https://phabricator.kde.org/settings/panel/emailpreferences/</a></div></div><br /><div><strong>To: </strong>bdhruve, bshah, Plasma on Wayland, graesslin<br /><strong>Cc: </strong>bshah, graesslin, plasma-devel, kwin, hardening, jensreuterberg, abetts, sebas<br /></div>
