Add Options flags similar to QFileDialog: - DontWatch: Do not use file system watchers for simple use cases like line edit completion. This brings it closer to QDirModel, which then can be deprecated. - DontResolveSymlinks: Similar to QFileDialog::DontResolveSymlinks. - DontUseCustomDirectoryIcons: matching QFileIconProvider::DontUseCustomDirectoryIcons for convenience. Task-number: QTBUG-76493 Change-Id: I09d3cb73ef902a700e6ebfba427e2d990fce4b4c Reviewed-by: Qt CI Bot <qt_ci_bot@qt-project.org> Reviewed-by: Volker Hilsheimer <volker.hilsheimer@qt.io>
