MacOS X上的QScrollArea透明背景 [英] QScrollArea transparent background on MacOS X

问题描述

我有一个问题，使 QScrollArea 的内容不绘制背景。

I have a problem with making contents of QScrollArea to not draw a background.

初始图片，当我没有应用样式表：

你可以看到，滚动区域的内容比整体框架更暗。

So here is the initial picture, when I apply no stylesheet: You can see, that the contents of scroll area are darker then the overall frame.

我找到了可以应用于滚动区域的样式表，因此背景是透明的。这里是我使用的样式表：

I have found the stylesheet that I can apply to scroll area, so the background is transparent. Here's the stylesheet I use:

QScrollArea { background: transparent; }
QScrollArea > QWidget > QWidget { background: transparent; }

问题是，当我这样做，scrollarea的滚动条被搞砸了：

Problem is that when I do that, the scrollbar of scrollarea gets messed up:

你看到了吗？

如何使我的样式表不影响滚动条，同时仍然将其应用到 QScrollArea ？

How can I make my stylesheet not to affect the scrollbar, while still applying it to the QScrollArea? Or what different stylesheet should I apply instead?

推荐答案

尝试为滚动区域视口设置对象名称：

try to set an object name for the scroll area viewport:

pScrollArea->viewport()->setObjectName("myViewport");

然后使用样式表中的hashtag属性在您的屏幕截图中，您的目标是让它们透明）：

then address it using the hashtag property in the stylesheet (also add the groupbox since the way I see it in your screenshot, your goal is to make them transparent as well):

QScrollArea, #myViewport, QGroupBox { 
  background: transparent;
}
