hello, anda_skoa:

According to your opinion ,i use Background or Window roles. however, i don't get the result as i except.

my code is :

QPalette::ColorRole role=ui->btn_curveColor->backgroundRole();
    curveColor=ui->btn_curveColor->palette().color(role);
    int r=curveColor.red();
    int g=curveColor.green();
    int b=curveColor.blue();
    int a=curveColor.alpha();
 
    QString role1=ui->btn_curveColor->windowRole();
 
    cout<<"Use backgroundRole :  r="<<r<<"\tg="<<g<<"\tb="<<b<<"\ta="<<a<<endl;
    cout<<"Use windowRole :  "<<role1.toAscii().data()<<endl;

QPalette::ColorRole role=ui->btn_curveColor->backgroundRole();
    curveColor=ui->btn_curveColor->palette().color(role);
    int r=curveColor.red();
    int g=curveColor.green();
    int b=curveColor.blue();
    int a=curveColor.alpha();

    QString role1=ui->btn_curveColor->windowRole();

    cout<<"Use backgroundRole :  r="<<r<<"\tg="<<g<<"\tb="<<b<<"\ta="<<a<<endl;
    cout<<"Use windowRole :  "<<role1.toAscii().data()<<endl;

To copy to clipboard, switch view to plain text mode 

I get :

Use backgroundRole :  r=236	g=233	b=216	a=255
Use windowRole :

Use backgroundRole :  r=236	g=233	b=216	a=255
Use windowRole :

To copy to clipboard, switch view to plain text mode 

in debug mode. i check the value of role is Button(1), and the role1 is a empty string.

help me please.

Seems the style sheet does not change the palette but somehow overrides it.

Too bad, seems you have to parse the stylesheet string yourself.

hi, anda_skoa.thank you all the same. i have to set the flat and AutoFillBackground attributes to true .so i get the result as i except.

code is :

ui->setupUi(this);
    ui->btn_curveColor->setFlat(true);
    ui->btn_curveColor->setAutoFillBackground(true);
    curveColor=ui->btn_curveColor->palette().color(QPalette::Button);
 
    int r=curveColor.red();
    int g=curveColor.green();
    int b=curveColor.blue();
    int a=curveColor.alpha();
 
    cout<<"r="<<r<<"\tg="<<g<<"\tb="<<b<<"\ta="<<a<<endl;

ui->setupUi(this);
    ui->btn_curveColor->setFlat(true);
    ui->btn_curveColor->setAutoFillBackground(true);
    curveColor=ui->btn_curveColor->palette().color(QPalette::Button);

    int r=curveColor.red();
    int g=curveColor.green();
    int b=curveColor.blue();
    int a=curveColor.alpha();

    cout<<"r="<<r<<"\tg="<<g<<"\tb="<<b<<"\ta="<<a<<endl;
