set QProgressDialog. progress indicator color?

[qlands]

Do you mean the progress bar on the QProgressDialog? If so, you can set its palette Highlight color to the color you want.

Maybe QProgressDialog constructs the progress bar with a default bar. To replace it just create a new QProgressBar* , change its color and replace it with setBar ( QProgressBar * bar )

QProgressBar * myBar = new QProgressBar(this);
 
QPalette palette1;
        QBrush brush2(QColor(192, 0, 0, 255)); //Some red color
        brush2.setStyle(Qt::SolidPattern);
        palette1.setBrush(QPalette::Active, QPalette::Highlight, brush2);
        palette1.setBrush(QPalette::Inactive, QPalette::Highlight, brush2);
        QBrush brush3(QColor(204, 199, 197, 255));
        brush3.setStyle(Qt::SolidPattern);
        palette1.setBrush(QPalette::Disabled, QPalette::Highlight, brush3);
        myBar->setPalette(palette1);
 
MyProgressDialog.setBar(myBar);

QProgressBar * myBar = new QProgressBar(this);

QPalette palette1;
        QBrush brush2(QColor(192, 0, 0, 255)); //Some red color
        brush2.setStyle(Qt::SolidPattern);
        palette1.setBrush(QPalette::Active, QPalette::Highlight, brush2);
        palette1.setBrush(QPalette::Inactive, QPalette::Highlight, brush2);
        QBrush brush3(QColor(204, 199, 197, 255));
        brush3.setStyle(Qt::SolidPattern);
        palette1.setBrush(QPalette::Disabled, QPalette::Highlight, brush3);
        myBar->setPalette(palette1);

MyProgressDialog.setBar(myBar);
