QColor with style sheets

I have a question about how to use QColor with style sheets.
Normally I would color my text by doing:

Code:

---

QLabel Label;
     Label->setStyleSheet( "color: rgb(100,200,200);" );

---

Now I'd like to specify the rgb color in QColor format (as shown below) but that won't work:

Code:

---

QLabel Label;
     mycolor = QColor(100,200,200); 
     x1Label->setStyleSheet( "color: mycolor;" );

---

I think I can not put QColor directly into the stylesheet.
So I also tried color: mycolor.toRgb(); but still didn't get it to work

So you want to dynamically specify colors... Well, you can't do it like that.
You can do it with a QString and placeholders:

Code:

---

QString style = "color: rgb(%1, %2, %3);";
label->setStyleSheet(style.arg(myColor.red()).arg(myColor.green()).arg(myColor.blue()));

Thanks Marcel,

I got your code to work but I don't know what the syntax is to combine what you suggested into the same style sheet with the other style declarations. For example both of the style sheet declarations below work but I can't put them together into one. What is the syntax? Thanks a lot!

Code:

---

mycolor = QColor(100,200,200);
 
     QString style = "background: rgb(%1, %2, %3);";
 
     drawButton->setStyleSheet(style.arg(mycolor.red()).arg(mycolor.green()).arg(mycolor.blue())); 
 
 
     drawButton->setStyleSheet(
                               "color:black; font-size:12px;"
                               "font-weight:bold;"
                               );

With the label colour it would be much simpler to use the palette...

Code:

---

QLabel label;
QPalette palette = label.palette();
palette.setColor(QPalette::Foreground, mycolor);
label.setPalette(palette);

Because the style sheet parameter is a QString, you can use all QString features, like the "+" and "+=" operators:

Code:

---

mycolor = QColor(100,200,200);
QString style = "background: rgb(%1, %2, %3);";
style = style.arg(mycolor.red()).arg(mycolor.green()).arg(mycolor.blue());
style += "color:black; font-size:12px;";
style += "font-weight:bold;";
drawButton->setStyleSheet(style);
