Hi,
i´m new here and try to make a very simple tool to input some data.
On the first hand i was unsure wich views are safe to use over android and ios, but after some time it looks like the one i search for is missing anyway.
I need a button with 4 states - unselected, on, type a and type b. I want to display this with circles inside the button.
With a idea in my head i start to build something like that. I look at the forum how to draw what i need and at the beginning it looks "ok". But then i add a timer to roll through the options - and i see the old element is stay there... My "canvas.clearRect(rect)" makes nothing. Than i add a filled background to my button, so the dots, in the code later, should be over this. Short answer - no, it works the first time, after that ist stays in this position.
Can anybody tell me what is wrong in my head...
"Drawing" has only one view, a Pane named "pnlDrawing"
Thank you
Matze
