Hi there
I would like to make a circular button lets say with a radius=1cm and after the user press it a ring will appear with the center be the same as the buttons center. After that I would like a glow effect follow the ring and after that when the user touches the ring lets say at 30 degrees and while he is draging his finger until lets say 120 degrees then the section of the ring from 30 to 120 degrees will change color.
Can anyone give me a hand here. I guess that in order to make the ring I will have to build a circle with the fill color to be trasparent and the strokewidth to be around 4. Unfortunately the rest like the glow effect that follus the ring and color change from the users touch and drag are totally out of my knowledge .
Eventually my coal is to build a clock style schedule in which some one can add an appointment by draging his finger on the ring lets say from 12:00 to 2:00 o clock and then this part of the ring will have a different color and a note relevant with the appointment.
