QProgressBar 3Color



  • Hello Qt community,
    can anyone tell me if it's possible to have several color in one progressbar and how to do that, as i know we can change the color and the background color using setstylesheet. so anyone have any idea how to do that.

    thank's for your help :)

  • Hi @benamiar , do you want something like this:-

    0_1560427795577_32f16319-5e08-4b99-838d-c6b0e9b5a269-image.png

    Here is the code for that:-

    QProgressBar *progbar = new QProgressBar;
    progbar->setStyleSheet("::chunk {"
                       "background-color: "
                       "qlineargradient(x0: 0, x2: 1, "
                       "stop: 0 green, stop: 0.6 green, "
                       "stop: 0.61 orange, stop: 0.8 orange, "
                       "stop: 0.81 red, stop: 1 red"
                       ")}");
    progbar->setValue(90);

    hello , tnx for your reply , so i think it's kind of what i want as i understood from what you did:

    set value will act on the 3 colors so we will have the 60% of 90% will be green , 20% of 90% will be orange and the rest will be red.

    for the background it's default one . am I wrong ?

    so qlinearGradient is the one who will allow us to have several color, i have another question is their anyway to do that withot the setstylesheet because behind it's using a parser so i don't know if their is a faster way to do that :) ?

    if for exemple i want to stay in 90% and want to change the % of the green without having the stylestyle what should i do ?
