Unsolved QprogressBar minValue and maxvalue changes different color

[benamiar]

Hello guys,
i need to create a QProgressBar where we can choose a range and also the minimim ans the maximum value.

the white value can change

 setStyleSheet(QString("QProgressBar{background-color: %2; border: 2px solid %2; border-radius: 1px; margin: 0px; text-align: center;}"
                          "Q2ProgressBar:disabled{background-color: %3; border: 2px solid %3; border-radius: 1px; margin: 0px; text-align: center;}"
                      "QProgressBar::chunk{background-color: qlineargradient(x0: 0, x2: 1, stop : 0 %1, stop: %5 %1, stop: 0.%6 %4, stop: 1 %4); margin: 0px}"
                         ).arg(Q2UiColorsLocator::get().getDispText().name(),
                               Q2UiColorsLocator::get().getDispText().name(),
                               Q2UiColorsLocator::get().getDisabled().name(),
                               Q2UiColorsLocator::get().getDispBackground().name())
                              .arg(min+0.00001)
                              .arg(((min)+0.00002)));

but seems to be like like a diy solution because each time we should add 0.0000001 to not have a gradiant color and also not working 100% so if you have any idea i'll take it thanks so much
