问：如何在QTableWidgetItem中显示QComboBox？

Question

I'm 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 that didn't the job.

so how to fix that? thanks.

Answer 1

You do this via the QTableWidget object itself.

1. Firstly you create your QComboBox
2. then call void QTableWidget::setCellWidget ( int row, int column, QWidget * widget )

Answer 2

Maybe you want to add a widget to a QTableWidget with

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

and accessing it by

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