Get background color of QPushbutton

Hi,all.

I have designed some QPushbutton controls using QT designer ,and set background color of the push-buttons to some color. Just like:
Attachment 10022, Now i only can get Qstring about background color by code:

Code:

---

QString str=ui->btn_curveColor->styleSheet();
    cout<<str.toAscii().data()<<endl;

---

.
it gives me :

Code:

---

background-color: rgb(0, 0, 255);

---

is there a simple way to get background-color in QColor format? I don't want to convert the string to color.

best wishes.

You could try through the button's palette. see QWidget::palette() and QPalette

hi ,anda_skoa :

i use code :

Code:

---

curveColor=ui->btn_curveColor->palette().button().color();
    //curveColor=ui->btn_curveColor->palette().color(QPalette::Button);  // have the same effect as the above.
    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;

---

however, i only get the output result :

Code:

---

r=236	g=233	b=216	a=255

---

that's the push-button's default background color, not the result

Code:

---

r=0 	g=0	b=255	a=255

---

as i except. how can i do?

best wishes.

Have you tried the Background or Window roles?

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 :

Code:

---

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;

---

I get :

Code:

---

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

---

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 :

Code:

---

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;
