--- Comment #8 from Guo Yunhe <i...@guoyunhe.me> --- Qt has officially ended support for Qt Quick Controls 1 https://bugreports.qt.io/browse/QTBUG-78117 We have to migrate the app to Qt Quick Controls 2. The TreeView seems not existing in Qt QuickControls 2. Maybe we have to redesign the component. -- You are receiving this mail because: You are watching all bug changes.
