Помогите вставить в модель QSplitter

[Jake Morgan]

Помогите вставить QSplitter в модель, не понимаю как с этим работать. И почему view1 и view2 не имеют цвет?

#include "sliderdelegate.h"
#include <QApplication>
#include <QStyleOptionProgressBar>
#include <QGraphicsView>
#include <QSplitter>
#include <QGraphicsScene>
#include <QOpenGLWidget>
SliderDelegate::SliderDelegate(QObject *parent) : QStyledItemDelegate (parent)
{

}

QWidget *SliderDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{

    QGraphicsView* view1 = new QGraphicsView(parent);

    view1->setBackgroundBrush(QBrush(Qt::green, Qt::SolidPattern));

    QGraphicsView* view2 = new QGraphicsView(parent);
    view2->setBackgroundBrush(QBrush(Qt::green, Qt::SolidPattern));


    QSplitter* splitter = new QSplitter(Qt::Horizontal);
    splitter->addWidget(view1);
    splitter->addWidget(view2);

    return splitter;

}

void SliderDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
{
    QSplitter *splitter = static_cast<QSplitter*>(editor);

    int value = index.model()->data(index, Qt::EditRole).toInt();

}

void SliderDelegate::setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const
{

    QSplitter* splitter = static_cast<QSplitter*>(editor);

}

void SliderDelegate::updateEditorGeometry(QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    editor->setGeometry(option.rect);
}

void SliderDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    

    //QApplication::style()->drawControl(QStyle::CE_ProgressBar, &progressBar, painter);
}
