Is it possible to move icon in QStandardItem?

TomNow99

Hi,

I have QStandardItemModel and I would like to add to this model items - QStandardItems and set this model in QComboBox.

My code:

    comboBox = new QComboBox(this);
    model = new QStandardItemModel;
    QStandardItem * newItem = new QStandardItem;
    newItem->setText("another text");
    newItem->setFlags(Qt::ItemIsUserCheckable | Qt::ItemIsEnabled);
    newItem->setData(Qt::Unchecked, Qt::CheckStateRole);
    QIcon icon(R"(pathTopng\another.png)");
    newItem->setIcon(icon);

    newItem->setSelectable(true);
    model->setItem(0, 0, newItem);

    comboBox->setModel(model);
    comboBox->resize(200,20);

My item looks like this:

I would like to move icon like this:

How Can I do this?

@TomNow99
Subject to being corrected, I don't think you can do that (certainly there is nothing obvious). You may be able to use a QStyledItemDelegate to achieve this, assuming it can be done.

@JonB I try with a QItemDelegate. Have I to draw it? Or is there a better way?

Use a delegate:

class StyledItemDelegate: public QStyledItemDelegate{
public:
   using QStyledItemDelegate::QStyledItemDelegate;
protected:
    void initStyleOption(QStyleOptionViewItem *option, const QModelIndex &index) const{
        QStyledItemDelegate::initStyleOption(option, index);
        option->decorationPosition = QStyleOptionViewItem::Right;
    } 
};

@eyllanesc Perfect!

@JonB @eyllanesc I have second question about similar problem.

No I would like to write our mousePressEvent() function in class which inherits QComboBox, but when I click in the popup view().

When I do that I only get clicks on dropdown menu and don't get clicks on popup (view()).

I know that I should do something with comboBox->view(), but I don't know what.

EDIT:

view()->viewport()->installEventFilter(this);
