    Hi guys,

    I’m looking for two things.

    The first is a curved line, along the lines of defining a start point and an end point and between points to ‘curve’. Is there anything like this in Felgo/Qt Quick?

    The second is to take this curved line, and draw it in a ‘dashed’ mode, rather than one solid line.

    Cheers in advance!

    The QML Canvas type allows to draw curves, for example with the bezierCurveTo(…) method.
    I don’t know of a simple way to make dashed lines though. Maybe you can find a custom solution online that works for you.





    Hi, KoolBanana. This function works for drawing dashed lines on a canvas: https://davidowens.wordpress.com/2010/09/07/html-5-canvas-and-dashed-lines/ Instead of adding the function to the context prototype, just set it on the context directly: context.dashedLineTo = function(...){...} Note that after drawing your line(s) you need to call context.stroke() in order to make them visible on your canvas.

    That doesn’t help you directly with curved dashed lines, but perhaps it’ll give you a start? Good luck.



    Hi Nathan,

    Much appreciated. I’ll definitely check this out and post any updates!




    Please do! If you get a working curved dotted line version, I’ll be interested to see it. 🙂 Good luck
