Could you help me? I want the user to be able to erase or edit the drawing they have done in the canvas area.

I have tried to work it out- no luck. I created a canvas area and a colour select button- thanks to your great little app you sent me. I want the users to be able to erase/ edit their drawing by tapping an erase button. Thanks for your help!

To allow the user to erase what they drew, you can use the SetEraseMode behavior (in the "Drawing" behaviors category). Within this behavior, you can select whether you are turning the eraser on or off. So for example the eraser button could have a Tap-SetEraseMode (on) action set, and it can switch with another button that shows that the eraser is on and will turn the eraser off when it is tapped.

Let us know if you'd like to see a sample app of this effect.
