Question

I am trying to delete all rows from a QTableWidget . Here is what I tried.

for ( int i = 0; i < mTestTable->rowCount(); ++i )
{
    mTestTable->removeRo         


        

Answer 1

In order to prevent an app crash, disconnect all signals from the QTableView.

// Deselects all selected items
ui->tableWidget->clearSelection();

// Disconnect all signals from table widget ! important !
ui->tableWidget->disconnect();

// Remove all items
ui->tableWidget->clearContents();

// Set row count to 0 (remove rows)
ui->tableWidget->setRowCount(0);
