Qt - QGraphicsView没有ScrollBar [英] Qt - QGraphicsView without ScrollBar

问题描述

我想使用QGraphicsScene显示一个图片在其全视图。但是，当我把QgraphicsScene里面的QGraphicsView，我得到一个滚动条。我试过这么多方式，但都是去静脉。因此，任何人都可以告诉我如何获得没有滚动条的完整视图。

I am trying to show a picture in it's full view using QGraphicsScene. But when ever I put the QgraphicsScene inside the QGraphicsView, I am getting a scroll bar. I tried so many ways But all are went to veins. So can anybody tell me how to obtain the full view without the scrollbar.

推荐答案

QGraphicsView v;
v.setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
v.setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);

要在隐藏后以编程方式调整滚动，请使用 v.ensureVisible（）。

To adjust the scrolling programmatically once these have been hidden, use one of the overloads of v.ensureVisible().
