问题描述
我知道有一个函数 QWidget :: setWindowOpacity（qreal level）但是在文档中写的这只适用于窗口。
I know that there is a function QWidget::setWindowOpacity(qreal level) but as written in the documentation this does only work for windows.
有一种方法可以让布局中的窗口部件不透明吗？
Is there a way to make widgets that are lying inside layouts opaque too?
我想做的是一个动画小部件正在消失。我曾经使用一个首选项对话框，并且它工作。
What I'm trying to do is an animation where widgets are fading in. I once did that with a preferences-dialog and there it worked.
因此，你认为有一种方法或解决方法来实现不透明度对于布局内的小部件？
So do you think there is a way or a work-around to achieve opacity for widgets inside layouts? How would you do that?
提前感谢！
