how to set the background color equal to background color of stylesheets

jsulm

@Qt-Enthusiast "This code is not working" - really, you should at least try to find out what is wrong in the code you get here!

I am getting black color as background color

I would understand if you get an unresolved overloaded function type error.
Because in the example I did not write rgb.red() as I should have but rgb.red, A clear sign, that I rely to heavily on Qt-Creators auto complete...

this works, I just tested this in a small example

QLabel *l = new QLabel();
    l->resize(50,50);
    l->show();
    QColor rgb(QWidget::palette().color(QWidget::backgroundRole()));
//    QColor rgb(150,150,150);
    QString style = QString("background-color: rgb(%1,%2,%3); border: 0px ;").arg(rgb.red()).arg(rgb.green()).arg(rgb.blue());
    l->setStyleSheet(style);
    connect(this, &Widget::destroyed, l, &QLabel::deleteLater);

What do you get as values, if you print your QColor in e.g. qDebug()?

My back ground color is wrong

color1.red 255 color gree 255 color blue 255 but in actual my background is grey how to get background color as grey

Eddy

the solution is in your previous post :
// QColor rgb(150,150,150);
but you commented it out

Do you understand the concept of RGB color values?

Qt Enthusiast

@Eddy I do understand the RGB values concept . but I do not want to set a harcorred color .,I want to keep the color of QLIneEdit same as that of it background , with out harding the RGB values my concern is
QColor rgb(QWidget::palette().color(QWidget::backgroundRole())); is not giving me proper background color of the frame ? how to get that

We already gave you the solution to that question in another post

Did you try it? What is not ok with that solution?

Qt Enthusiast

no the color mismacthes from background and it is not perfect macth

Eddy

Could you show us an image of the actual background with the lineedit in it?
What OS are you on?

You should do somethig like this

std:string clr = "background-color: rgb(" + std::to_string(color.red()) + "," + std::to_string(color.green()) + "," + std::to_string(color.blue()) + "); border: 0px;";
setStyleSheet(clr.c_str());

Another way:

setStyleSeet("background-color: transparent; border 0px;");

I will try
