All QStyleOptionButton in listview sunken when clicking one of them

[jiveaxe]

This is my constructor:

ItemDelegate::ItemDelegate(QObject *parent) :
    QAbstractItemDelegate(parent)
{
    _state =  QStyle::State_Enabled;
}

ItemDelegate::ItemDelegate(QObject *parent) :
    QAbstractItemDelegate(parent)
{
    _state =  QStyle::State_Enabled;
}

Thanks for your patience

I solved changing approach; I'm not using anymore _state member but int _currRow to track clicked button; here it is a sample code:

ItemDelegate::ItemDelegate(QObject *parent) :
    QAbstractItemDelegate(parent)
{
    _currRow = -1;
}
 
void ItemDelegate::paint ( QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index ) const
{
    if (!index.isValid())
        return;
 
    QApplication::style()->drawPrimitive(QStyle::PE_PanelItemViewItem, &option, painter, 0);
 
    ...
 
    QStyleOptionButton button;
    button.rect = buttonRect;
    button.features |= QStyleOptionButton::Flat;
 
    if(_currRow == index.row())
        button.state = QStyle::State_Sunken | QStyle::State_Enabled;
    else
        button.state = QStyle::State_Raised | QStyle::State_Enabled;
 
    QApplication::style()->drawControl(QStyle::CE_PushButton, &button, painter);
}
 
bool ItemDelegate::editorEvent(QEvent *event, QAbstractItemModel *model, const QStyleOptionViewItem &option, const QModelIndex &index)
{
    Q_UNUSED(model)
 
    if( event->type() != QEvent::MouseButtonPress &&
        event->type() != QEvent::MouseButtonRelease ) {
        return true;
    }
 
    if( event->type() == QEvent::MouseButtonPress)
        _currRow = index.row();
    else
        _currRow = -1;
 
    ...
 
    QMouseEvent* mouseEvent = static_cast<QMouseEvent*>(event);
    if( !buttonRect.contains( mouseEvent->pos()) ) {
        return true;
    }
 
    if( event->type() == QEvent::MouseButtonRelease) {
        // call slot
    }
 
    return true;
}

ItemDelegate::ItemDelegate(QObject *parent) :
    QAbstractItemDelegate(parent)
{
    _currRow = -1;
}

void ItemDelegate::paint ( QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index ) const
{
    if (!index.isValid())
        return;

    QApplication::style()->drawPrimitive(QStyle::PE_PanelItemViewItem, &option, painter, 0);

    ...

    QStyleOptionButton button;
    button.rect = buttonRect;
    button.features |= QStyleOptionButton::Flat;

    if(_currRow == index.row())
        button.state = QStyle::State_Sunken | QStyle::State_Enabled;
    else
        button.state = QStyle::State_Raised | QStyle::State_Enabled;

    QApplication::style()->drawControl(QStyle::CE_PushButton, &button, painter);
}

bool ItemDelegate::editorEvent(QEvent *event, QAbstractItemModel *model, const QStyleOptionViewItem &option, const QModelIndex &index)
{
    Q_UNUSED(model)

    if( event->type() != QEvent::MouseButtonPress &&
        event->type() != QEvent::MouseButtonRelease ) {
        return true;
    }

    if( event->type() == QEvent::MouseButtonPress)
        _currRow = index.row();
    else
        _currRow = -1;

    ...

    QMouseEvent* mouseEvent = static_cast<QMouseEvent*>(event);
    if( !buttonRect.contains( mouseEvent->pos()) ) {
        return true;
    }

    if( event->type() == QEvent::MouseButtonRelease) {
        // call slot
    }

    return true;
}
