Converting From Hexadecimal to QString



  • Hi Guys,
    This is my first post here and I'm hoping you can help me out. I've a project in which I have to implement unions so I'm doing so with a packed representation and component-wise representation of a hexadecimal color. The code below will clear things up but basically I'm stuck on how to convert from the hexadecimal to a QString so that I can use it in the stylesheet. If you have any ideas I'd really appreciate your help cause I've been unable to find an answer for the past few hours.

    //union
    typedef union color4bTag
        {
        unsigned int      c;    // packed representation
        struct argbTag          // component-wise representation
            {
            unsigned char b;    // (reversed for intel storage order)
    
            unsigned char g;
            unsigned char r;
            unsigned char a;
            } argb;
        } COLOR4B;
    
    
    //setting color.c
        color4bTag color;
        color.c = 0x000000FF;
    
    //stylesheet
        QString styleSheet(
          "QMainWindow{background-color: %1;}
        );
    
    //seting background color
    QString varBGColour(/*What do I put here to get #000000FF*/);
    
    setStyleSheet(styleSheet.arg(varBGColour));

    What's the point of c here?
