How to check if no treeitem is selected in the tree view
-
Assuming a QTreeView, I believe selectionModel() is not relevant. The inherited abstract class contains direct access to currentIndex() and the returned object contains status methods for the index.
-
This is how i get the selected item in the tree view.
QModelIndex index = currentTreeView->selectionModel()->currentIndex();How would i get to know if no item is selected in the tree view.

@Kent-Dorfman may know more than I, but be careful: in Qt current items are not necessarily the same as selected items....You can try his way. For my part I would first have looked at
currentTreeView->selectionModel()->selectedIndexes().count() == 0, or directly fromcurrentTreeView->selectedIndexes().count() == 0. -

correct, and it's also explained in the docs: https://doc.qt.io/qt-5/model-view-programming.html#current-item-and-selected-items
