how to disable selection of cells with widgets on qtablewidget

JoeCFD

I know how to make items unselectable on qtablewidget. I have a customized widget(button) and add it to some cells by calling setCellWidget(row, coln, widget);
However, clicking it will trigger table selection which I want to avoid. Any way to make these cells unselectable?

OS: Ubuntu 18 and QT: 5.15.2

It's unclear to me exactly what you are asking, but with my limited understanding...maybe implement setEnabled() for your custom widget, and disable the relevant ones.

Set its selection mode to QAbstractItemView::NoSelection.

Thanks for your help, guys.

My table is defined as

    m_tableWidget->setSelectionMode( QAbstractItemView::MultiSelection );
    m_tableWidget->setSelectionBehavior( QAbstractItemView::SelectRows );

    auto button = new MyButton( this );
    m_tableWidget-> setCellWidget(row, coln, button);

the row is selected when button is pressed. What I want is the row is not selected when button is pressed.

@JoeCFD said in how to disable selection of cells with widgets on qtablewidget:

auto button = new MyButton( this );
m_tableWidget-> setCellWidget(row, coln, button);

Adding a new item to the same cell solves the problem. cell widget seems to be laid out on top of the item.

    auto new_item = new QTableWidgetItem;
    new_item->setFlags( column_item->flags() & ~Qt::ItemIsSelectable );
    m_tableWidget->setItem( row, coln, new_item);
    auto button = new MyButton( this );
    m_tableWidget-> setCellWidget(row, coln, button);
