take screenshots. On Wayland we addressed this by making the screenshot<br />
process interactive. The user has to confirm explicitly that a<br />
screenshot is taken. But our API still allows to create a screenshot and<br />
save it directly to a temporary file. It shows a notification, but<br />
nevertheless it is a small security issue.</p>
<p>Thus this change addresses it by sending a dbus error in case the<br />
methods are called on Wayland.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Run nested session before and after change and used qdbusviewer<br />
to call screenshot. Before path was returned, after change no path was returned.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R108 KWin</div></div></div><br /><div><strong>BRANCH</strong><div><div>screenshot-unsupported-wayland</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D22209">https://phabricator.kde.org/D22209</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>effects/screenshot/screenshot.cpp</div></div></div><br /><div><strong>To: </strong>graesslin, KWin<br /><strong>Cc: </strong>kwin, LeGast00n, sbergeron, jraleigh, fbampaloukas, GB_2, mkulinski, ragreen, jackyalcine, Pitel, iodelay, crozbo, bwowk, ZrenBot, ngraham, alexeymin, himcesjf, lesliezhai, ali-mohamed, hardening, jensreuterberg, abetts, sebas, apol, mart<br /></div>
