[SOLVED] QTreeview Double Clicked "The program unexpectedly finished"

[takoo]

hi ```

I get error (QSortFilterProxyModel: index from wrong model passed to mapToSource)
void MainWindow::on_treeView_doubleClicked(const QModelIndex &index)
{

if(index.isValid())
{
QModelIndex mapped=filter->mapToSource(model->index(dir));

    qDebug()<<model->filePath(mapped);
 }

}

[mrjj]

oh
maybe its
mapToSource(index)

[takoo]

Thanks everybody
