Canvas / Context2D in Qt4.8

Mark81

With a project I need to use the very old Qt4.8 and I cannot use the Canvas object to draw with Context2D. I tried to search in the docs but I'm not sure what was the right method on that release.

Hi,

What are you trying to do ?

Something like this:

Canvas {
        id: canvas
        anchors.fill: parent

        onPaint: {
            var ctx = canvas.getContext('2d');
            ctx.reset();

            ctx.lineWidth = 4;
            ctx.strokeStyle = "red"
            ctx.beginPath()
            ctx.moveTo(root.width / 2, 24)
            ctx.lineTo(root.width * 0.9, 24)
            ctx.stroke()

            ctx.beginPath()
            ctx.fillStyle = "red"
            ctx.arc(root.width * 0.9, 24, 6, 0, 360)
            ctx.fill()
     }
}

You'll have to do a "reverse port". See here for the differences between QtQuick 1 and 2

Most of the link lead to error 404. I will try to Google them. Thanks

The documentation has changed a bit. The links have been updated.
