From 4625964bb1177df2c0cd463e16c36c9fa47db3e5 Mon Sep 17 00:00:00 2001 From: ispyisail Date: Thu, 18 Jun 2026 21:09:49 +1200 Subject: [PATCH] Fix #159: reset unused-element highlight when elements become used again ElementsCollectionModel::highlightUnusedElement() only ever painted the currently-unused elements red; it never cleared the background of items that were no longer unused. So when an element was re-added to a project and saved, its red 'unused' highlight persisted until the model was rebuilt from scratch. Reset every item's background before re-applying the highlight to the current unused set. --- sources/ElementsCollection/elementscollectionmodel.cpp | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/sources/ElementsCollection/elementscollectionmodel.cpp b/sources/ElementsCollection/elementscollectionmodel.cpp index a55eb523e..ae687da72 100644 --- a/sources/ElementsCollection/elementscollectionmodel.cpp +++ b/sources/ElementsCollection/elementscollectionmodel.cpp @@ -538,6 +538,11 @@ QList ElementsCollectionModel::project() const */ void ElementsCollectionModel::highlightUnusedElement() { + //Reset the background of every item first, so elements that are no + //longer unused lose their previous red highlight (issue #159). + for (ElementCollectionItem *eci : items()) + eci->setBackground(QBrush()); + QList unused; foreach (QETProject *project, m_project_list)
