Qt jpg图片显示 [英] Qt jpg image display

问题描述

我想在 Qt UI 中显示 .jpg 图像.我在网上查了一下，发现 http://qt-project.org/doc/qt-4.8/widgets-imageviewer.html.我认为 Graphics View 会做同样的事情，而且它还有用于显示视频的编解码器.如何使用图形视图显示图像?我浏览了图书馆，但因为我是 Qt 的新手，我找不到开始的线索.你能告诉我一些关于如何在 Qt 中加载和显示图像的资源/示例吗?

I want to display .jpg image in an Qt UI. I checked it online and found http://qt-project.org/doc/qt-4.8/widgets-imageviewer.html. I thought Graphics View will do the same, and also it has codec to display video. How to display images using Graphics View? I went through the libraries, but because I am a totally newbie in Qt, I can't find a clue to start with. Can you direct me to some resources/examples on how to load and display images in Qt?

谢谢.

推荐答案

#include ...

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QGraphicsScene scene;
    QGraphicsView view(&scene);
    QGraphicsPixmapItem item(QPixmap("c:\test.png"));
    scene.addItem(&item);
    view.show();
    return a.exec();
}
