Emit countChanged on layoutChanged (!261) · Merge requests · Plasma / libplasma · GitLab

Konrad Materka requested to merge work/kmaterka/437519_emit_countChanged_on_layoutChanged into master May 23, 2021

We need to emit countChanged every time size of the model changes. Usually listening on rowsInserted and rowsRemoved is enought, but if source model is of type QSortFilterProxyModel then it is possible that rows are removed but layoutChanged is emitted. Check: https://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/itemmodels/qsortfilterproxymodel.cpp?h=5.15.2#n1473
