[Interest] Gradient Line

Try setting the finalStop constructor argument to QPointF(0.0, opt.rect.height() - 2). From the documentation:

Note: The expected parameter values are in pixels.

Hi.

Is it possible to draw single line with gradient?

I've tried something like this:

QLinearGradient g( QPointF( 0.0, 0.0 ), QPointF( 0.0, 1.0 ) );

g.setCoordinateMode( QGradient::ObjectBoundingMode );

g.setColorAt( 0.0, QColor( 50, 50, 60 ) );

g.setColorAt( 0.5, QColor( 140, 140, 150 ) );

g.setColorAt( 1.0, QColor( 50, 50, 60 ) );



p->setPen( QPen( QBrush( g ), 1.0 ) );

p->drawLine( 1, 2, 1, opt.rect.height() - 2 );

But this draws line with average color of gradient: QColor( 105, 105, 115 )
