QWidget背景图片适合 [英] QWidget background-image fit

问题描述

我正在使用Qt 4.7，我将QWidget的背景图像CSS设置为来自我的qrc的图像.

I'm working with Qt 4.7 , I set a QWidget's background-image CSS an image from my qrc.

问题是图像的分辨率很高，并且仅显示了图像的左上部分，我无法按比例缩小图像以适合显示.在CSS3中，我看到了"background-size:contain"属性，但我担心它在Qt 4.7中不起作用.

The problem is the image is High res , and only the upper left part of it is showing , I can't get it to scale down to fit. In CSS3 I saw a "background-size : contain" property but I fear it doesn't work in Qt 4.7.

找不到使图像适合窗口的方法.有任何想法吗 ? 我不介意以编程方式进行操作.

Couldn't find a way to make the image fit the window. Any ideas ? I don't mind doing it programmatically .

谢谢

推荐答案

如果QFrame与图像的宽高比相同，则可以在QFrame上使用CSS，如下所示:

If the QFrame is the same aspect ratio as the image you can use CSS on the QFrame like this:

QFrame
{
   border-image: url(:/images/myimage.png) 0 0 0 0 stretch stretch;
   border-width: 0px;
}
