color setting idiom

[ugluk]

As I cannot set the alpha channel in any constructor of the QColor class, I am reduced to the following color-setting idiom:

QColor color;
 
color.setRgba(QRgb(0x88FFFFFF));
glossyGradient.setColorAt(0, color);
 
color.setRgba(QRgb(0x55FFFFFF));
glossyGradient.setColorAt(.1f, color);
 
color.setRgba(QRgb(0x33FFFFFF));
glossyGradient.setColorAt(.5f, color);
 
...

QColor color;

color.setRgba(QRgb(0x88FFFFFF));
glossyGradient.setColorAt(0, color);

color.setRgba(QRgb(0x55FFFFFF));
glossyGradient.setColorAt(.1f, color);

color.setRgba(QRgb(0x33FFFFFF));
glossyGradient.setColorAt(.5f, color);

...

This really isn't something to look at. Do there exist other possibilities?
