I am facing a problem with a graphicsLineItem in a graphicsView. The lineItem is activated by a selection made on a tabWidget. The issue is that the lineItem is not highlighting when the appropriate item on the tabWidget is clicked, rather it highlights when the mouse hovers over the graphicsView.
I feel its cause the graphicsView is not refreshing, but use of update with sceneRect() as parameter is not solving te problem.
Need some suggestions and solutions for the same.
