在QT中从样式表访问填充 [英] Accessing padding from stylesheet in QT

问题描述

我有一个自定义的QWidget子类，该子类列出了许多子级.在我的样式表中，我定义了一个背景，效果很好.我还定义了填充，这是行不通的.我显然需要为此提供支持.

I have a custom QWidget subclass that lays out a number of children. In my stylesheet I define a background, which works fine. I also define padding, which doesn't work. I clearly need to provide support for this myself.

要做到这一点，我需要能够找出在我的小部件的样式表中设置了哪些填充.我不想自己解析样式表，这没有多大意义.如何访问样式表中的顶部，左侧，底部和右侧填充?

To do that, I need to be able to find out what padding is set in the stylesheet for my widget. I do not wish to parse the stylesheet myself, that would not make much sense. How can I access the top, left, bottom and right padding set in the stylesheet?

预先感谢
