Qt: How to display a QComboBox inside a QTableWidgetItem?

Question

Im trying to display a QComboBox inside a QTableWidgetItem by setting it as its child using this code:

QComboBox* qcb;
int r,c;
//......
qcb->setParent((QWidget*)tableWidget->item(r,c));

but it did not help.

so how to fix it? thank.

Answer 1

You do this through the object itself QTableWidget.

• First, you create your QComboBox
• then call void QTableWidget::setCellWidget ( int row, int column, QWidget * widget )

Answer 2

Perhaps you want to add a widget to a QTableWidget using

void QTableWidget::setCellWidget ( int row, int column, QWidget * widget )

and access it using

QWidget * QTableWidget::cellWidget ( int row, int column ) const
