Hi,

I want to make the green circle move through the big grey circle as if it is a progress bar...

i am not at all sure how to accomplish this,for my part i think it would be somehow through QPainterPath,its what i think....

also i cannot understand the CubicTo() function of QpainterPath..the diagram in the document http://doc.trolltech.com/4.4/qpainterpath.html#cubicTo

makes it even more confusing for me..any help ..atleast on the first question

Hi,
Thanks ..but there is no function as pointAt ...i found a function named as pointAtPercent()... http://doc.trolltech.com/4.4/qpainterpat…#pointAtPercent..
also the green circle which i want to move is the painterPath while i have drawn the grey circle as a Painter..

correct me if i am wrong...what you mean here is that green circle and grey circle both should be Graphics Item ? also i cannot find path() function which you mentioned in
greenCircle->setPos( greyCircle->path().pointAtPercent( pc ) ) .. and can you be more clear with the last part of this statment ...
i mean ->path().pointAtPercent( pc )..
Thanks Again..

are you sure that path() function should be used...because
path does this function..'Returns the path. This may contain symbolic links, but never contains redundant ".", ".." or multiple separators.'..chk out the link

Thanks for your reply...can you please also clear that green circle and grey circle both should be Graphics Item ?..beacuse upuntil now i have drawn green circle with the help of QPainterPath and using fill path() as you can see below...so do i have to change the below code ...

void ProgressWidget::paint(QPainter *painter, const QStyleOptionGraphicsItem *option,
QWidget *widget)
{
painter->save();
painter->setPen(QPen(QBrush(Qt::gray,Qt:: solidPattern),30,Qt:: solidLine,Qt::FlatCap,Qt::MiterJoin));
painter->drawEllipse(0, 0, 200, 200);
painter->restore();
painter->fillPath( path, QBrush( Qt::green, Qt:: solidPattern ) );
}
