How to get selected text in QTableWidgetItem?

Question

Qt

There is a QTableWidgetItem. it is necessary to receive a part of the text from QTableWidgetItem which was selected by the user. How can this be done? or maybe replace QTableWidget with something else?
and question 2: in order for the text to become editable, you need to double-click on the QTableWidgetItem. Is there a way to make it enter edit mode right away?

Answer 1

one:

if (QLineEdit* cw = dynamic_cast<QLineEdit*>(m_tableWidget->cellWidget(m_tableWidget->currentRow(), m_tableWidget->currentColumn())))
      qDebug() << cw->selectedText();

2:

m_tableWidget->setEditTriggers(QAbstractItemView::AllEditTriggers);
