SetHorizontalScrollBar deletes the scrollbar instead of the former scrollbar and has no effect in my QGraphicsview
I have added a new Qt Designer Form Class by Template QTabWidget and in the center of it I have placed a QGraphicsview to which I would like to replace the horizontal and vertical ScrollBars with other scrollbars in my layout.
I have highlighted the QGraphicsview and scrollbars in the image below!http://tech-it.gr/Screenshot1.JPG(Layout Screenshot)!
The problem is that the following command line, instead of replacing the horizontal scroll bar with the one I have in my layout, it deletes my horizontalscrollbar.
Could anyone tell me why could this be happening?
I have uploaded the project zip here "Your text to link here...":http://tech-it.gr/example.zip
