<p>model.isDir() does indeed, but this uses model.isDir, which is a data role. The FolderView::data() implementation already uses a cache. The cache is inserted into the first time isDir() is called and evicted e.g. on item deletion. It normally shouldn't stat.</p>
<p>This makes me wary of this patch because I don't want us to adopt an anti-pattern of caching model data as Qt Quick var copies. I expect Qt Quick to be smart enough to optimize model access.</p>
<p>I assume you did this based on profiling? Maybe data() is broken?</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R119 Plasma Desktop</div></div></div><br /><div><strong>BRANCH</strong><div><div>master</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D7204" rel="noreferrer">https://phabricator.kde.org/D7204</a></div></div><br /><div><strong>To: </strong>davidedmundson, mart<br /><strong>Cc: </strong>hein, plasma-devel, ZrenBot, progwolff, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, mart, lukas<br /></div>
