<p>So the signal blocker cannot be removed on Linux at least.</p>
<p>I wonder though, isn't there a risk anyway of these functions calling each other in a loop? Couldn't both functions just check if the given widget is already current (or given view is already the active one) and return immediately if that's the case?<br />
Removing the signal blocker would still lead to activeView() being called twice in that case, but at least the 2nd invocation shouldn't do anything in that case.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R33 KDevPlatform</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D7179" rel="noreferrer">https://phabricator.kde.org/D7179</a></div></div><br /><div><strong>To: </strong>rjvbb, KDevelop<br /><strong>Cc: </strong>kfunk, kdevelop-devel, geetamc, Pilzschaf, akshaydeo, surgenight, arrowdodger<br /></div>
