问题描述
是否可以在运行时在Qt中查找样式表值？
Is it possible to look up stylesheet values at runtime in Qt?
我正在使用一个来自QPushButton的自定义按钮，它有一些样式表属性设置。我想能够查找一些样式表设置，如边框宽度，边距，padding-top，padding-left，padding-right等。这是可能的，没有调用widget-> getStyleSheet（）和解析。
I'm working on a custom button derived from QPushButton that has some stylesheet properties set. I'd like to be able to look up some stylesheet settings like border width, margin, padding-top, padding-left, padding-right, etc. Is this at all possible to do without calling widget->getStyleSheet() and parsing out the values myself?
推荐答案
不要这样，你可以通过绘制代码来找到一些东西。但是解析和样式表的应用程序是非常优化的，并且使用了很多预处理。我甚至不认为你可以获得一个小部件的样式表，如果它实际上设置在父级。
Don't think so, you might be able to find something by stepping through the drawing code. But the parsing and the application of stylesheets is pretty optimised and uses a lot of preprocessing. I don't even think that you can get to the stylesheet of a widget if it was actually set in a parent.
