Qt样式表和“一个论点”问题

Question

I usually find a workaround for this, however it is getting on my nerves lately and I cannot find any information regarding it anywhere on the internet.

Right, I want to change the property of a progress bar I have in Qt and have set the initial values in the form designer.

This is what I have in my initial (and working) style sheet configuration:

QProgressBar {
    border: 2px solid grey;
    border-radius: 7px;
}

QProgressBar::chunk {
    background-color: #05B8CC;
    width: 20px;
}

(NOTE: Bare in mind that I have done it in the Form Designer, which is the inbuilt drag and drop graphical designer for Qt)

However, I want to change it programmatically within the code by doing this:

ui->progressBar->styleSheet("QProgressBar::chunk { background-color: #05B8CC; width: 20px;}"); 

According to the documentation for style sheets , it should be working with not problem whatsoever, but I get the following non-nonsensical error:

D:\Qt Projects\test\mainwindow.cpp:165: error: C2660: 'QWidget::styleSheet' : function does not take 1 arguments

Any ideas on what might be causing this?
