Draw bezier curve in qt

[illunara]

Hi everybody
How can i draw a bezier curve in QT?, is QPainterPath the one i need? Also, can i use a SVG file as a QRect?

Thanks

Ya, QPainterPath provides "cubicTo":

http://qt-project.org/doc/qt-4.8/qpainterpath.html#cubicTo

"Adds a cubic Bezier curve between the current position and the given endPoint using the control points specified by c1, andc2."

What do you mean by using an SVG as a QRect? Do you meant to get a bounding box from it?

QSvgRenderer has a boundsOnElement() method which gives you the bounding box of a specific element in an svg file:

Oh, it returns an QRectF, so we can use it later. As always, thank Justin XD
