Creating online line using canvas
how can i a create a line between two dynamic point using canvas...
and also a want to have a point in middle of line for give curvature to it...
something like this shape with an ability to change zeros position....
I think "this":http://qt-project.org/doc/qt-5/qtquick-canvas-example.html might help you for drawing curves. And "this":http://www.w3schools.com/tags/canvas_lineto.asp for drawing line between two points.
