Vertical scrolling with the mouse wheel in QGraphicsView in versions 5.15.1 and 6.6.1

[VVS]

In version 5.15.1, if the mouse cursor is over a widget (as in the example below - QTextEdit), there is scrolling for the entire QGraphicsView. In version 6.6.1, scrolling only occurs when the mouse cursor is not over QTextEdit. Is it possible to achieve the behavior that was present in version 5.15.1 ?

#include <QGraphicsScene>
#include <QGraphicsView>
#include <QVBoxLayout>
#include <QTextEdit>
#include <QWidget>
#include <QGraphicsProxyWidget>
 
MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 
    QGraphicsScene*scene=new QGraphicsScene(1,1,109,1199);
 
    QGraphicsView* graphicsView = new QGraphicsView(scene);
 
    setCentralWidget(graphicsView);
 
    graphicsView->setFrameShape(QFrame::NoFrame);
 
    QTextEdit* textEdit = new QTextEdit();
 
    QGraphicsProxyWidget* proxyWidget = new QGraphicsProxyWidget();
    proxyWidget->setWidget(textEdit);
 
    scene->addItem(proxyWidget);
 
    textEdit->move(-100,500);
}

#include <QGraphicsScene>
#include <QGraphicsView>
#include <QVBoxLayout>
#include <QTextEdit>
#include <QWidget>
#include <QGraphicsProxyWidget>

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QGraphicsScene*scene=new QGraphicsScene(1,1,109,1199);

    QGraphicsView* graphicsView = new QGraphicsView(scene);

    setCentralWidget(graphicsView);

    graphicsView->setFrameShape(QFrame::NoFrame);

    QTextEdit* textEdit = new QTextEdit();

    QGraphicsProxyWidget* proxyWidget = new QGraphicsProxyWidget();
    proxyWidget->setWidget(textEdit);

    scene->addItem(proxyWidget);

    textEdit->move(-100,500);
}

Hello,
I had something similar.
What I did was define a new class daughter of QTextEdit, make sure that its parent is the QGraphicView, and redefine wheelEvent so that it calls the parent's wheelEvent.
In python :

from PySide6.QtWidgets import QTextEdit
 
class NewTextEdit(QTextEdit):
    def __init__(self, parent):
        super().__init__(parent)
        self.parent = parent
 
    def wheelEvent(self, event):
        self.parent.wheelEvent(event)
        return True

from PySide6.QtWidgets import QTextEdit

class NewTextEdit(QTextEdit):
    def __init__(self, parent):
        super().__init__(parent)
        self.parent = parent

    def wheelEvent(self, event):
        self.parent.wheelEvent(event)
        return True
