文章标签： qt识别html style

作者在使用Python和Qt4.8创建GUI时，尝试通过CSS为QLabel内的表格元素赋予不同颜色，但发现类选择器并未被Qt识别。文章探讨了可能的原因，是否是Qt对CSS选择器支持的限制，或者使用方法上的误解。

I have a QLabel in my Python/Qt 4.8 GUI, which contains a table. I'd like to style elements of this table with different colours. I realise I can use tags but it seems a little more elegant to use classes and CSS. I want it to look like this:

My HTML looks like this:

Wavelength:	{0:.2f} µm
Bandwidth:	{1:.2f} µm
Power:	{2:.1f} mW
{3:.0f} sec stability:	{4:.1%} rms
	{5:.1%} p2p

And my CSS like this:

#oldPM {color: #333333}

#spec {color: blue}

#newPM {color: #333333}

But Qt doesn't seem to recognise the class selectors. Is this a fundamental limitation of the Qt styling, or am I doing something wrong? I can get it to change the style of the whole QLabel, using QLabel as a selector, but I want different parts of it to be styled differently.
