n-2204

I have two table table1 and table2
and in table1 i have option to add and del row so in table 2 i want rows as same as in table1 as if row added /del in table1 it should update in table2 as well
how to do this ?
thanks in advance

connect(ui.tableView_1->model(), &QAbstractItemModel::rowsInserted, ui.tableView_2->model(),[&](const QModelIndex& parent, int first, int last){ui.tableView_2->model()->insertRows(first,1+last-first,parent);});
and so on

VRonin

You just need to connect a slot to table1,&QAbstractItemModel::rowsRemoved/table1,&QAbstractItemModel::rowsInserted that deletes/inserts the coresponding row in table2

@VRonin said in Qtableview add rows based on other Qtableview:

QAbstractItemModel::rowsRemoved

you mean using removeRow()and insertRow ?
bool QAbstractItemModel::removeRow(int row, const QModelIndex &parent = QModelIndex())
bool QAbstractItemModel::insertRow(int row, const QModelIndex &parent = QModelIndex())

like this ??

connect(ui.tableView_1->model(), &QAbstractItemModel::rowsInserted, ui.tableView_1->model(), [ui.tableView_1- >model()](const QModelIndex& parent, int first, int last)
QAbstractItemModel* table1 = ui.tableView_1->model();
QAbstractItemModel* table2 = ui.tableView_2->model();
connect(table1, &QAbstractItemModel::rowsRemoved, table2, [table2](const QModelIndex& parent, int first, int last)

and so on
