Question

I’m using Qt with C++ using Qt Creator. I have a QGraphicsView in my window named render and I wish to set its scene programatically. In window.cpp:

QGraphicsScene* scene = new QGraphicsScene();
ui->render->scene(scene*);

I have included QtGui and QGraphicsView.

When I attempt to compile the program I get:

error: expected primary-expression before ')' token

Does anybody have any advice with regards to this issue?

Answer 1

QGraphicsView::scene() returns the scene, use setScene(QGraphicsScene* scene) to set it. You are also adding an asterisk after scene, which when used after an object usually means to multiply it – that’s why it’s expecting another something before ‘)’.
