void Four_in_a_row::resizeEvent(QResizeEvent *f)
{
 
    newwidth=f->size().width();
    newheigth=f->size().height();
    ui->mainframe->setGeometry(0,0,newwidth,newheigth);
    qView->setProperty("width", 500);
    qDebug()<<qView->width();

{
void Four_in_a_row::resizeEvent(QResizeEvent *f)
{
    
    newwidth=f->size().width();
    newheigth=f->size().height();
    ui->mainframe->setGeometry(0,0,newwidth,newheigth);

For example you can set a value for some property of an object which is exported to QML. If you bind this property from within QML with some other properties, they will be updated.

In general look here:
