QComboBox listview in separate dialog

[pkj]

QComboBox::model(). Use it to get the model and have a independent QListView in your dialog. Set the model of this QListView to the model from QCombobox.

Thanks for the hint.
I tried changing the dialog constructor to this:

ComboList::ComboList(QWidget *parent, QAbstractItemModel *pListModel, QString strTitle):
    DialogExt(parent)

ComboList::ComboList(QWidget *parent, QAbstractItemModel *pListModel, QString strTitle):
    DialogExt(parent)

To copy to clipboard, switch view to plain text mode 

And set up the model like this:

m_pList = new QListView(this);
    m_pList->setModel(pListModel);

m_pList = new QListView(this);
    m_pList->setModel(pListModel);

To copy to clipboard, switch view to plain text mode 

This however gives the same result as initially. The dialog view is populated correctly, but the selected item is not set in the dialog list. And when selecting something here, the original combobox does not show the changed item.

If you need the selected items to be in sync then you need to share the selection model. A selection model belonging to one view can be obtained using the view's selectionModel() function, and shared between many views with setSelectionModel().
Get QComboBox::view()::selectionModel(). Then QListView::setSelectionModel(...)
