MVC pattern with QGraphicsItem
-
Hi, I have made a simple MVC with a box that contains text. I have controller, which handles all the requests from outside, the model which stores the data and view which represents the cube itself on QGraphicsScene. My question is how to register a double-click, or mouse release on the view, when it cannot send signals, nor can include the controller, because of circular include?

No but QGraphicsObject Class adds just that if it's what you are missing.

Hi and welcome to devnet,
Why do you have circular dependencies ?
What type of item are you using ?
-
@SGaist No circular dependencies just yet - that was just a horrible idea I had and thankfully did not implement :D So far there is a QGraphicsItem that is the view, with another class, of QWidget, which is supposed to be the controller. I am just curious how to detect on the controller, that the view was double-clicked for example.
-
Emit a signal from the view that you will connect on the controller.
