I'm trying to draw string on a canvas. It is very long and it gets cut off because its not fitting into the screen. Please help me with any sample code that would draw a long string on a canvas and wrap it so that it won't get cut of and also implement vertical scrolling of the string. Thanks.

You'll have to divide the long string into multiple lines based on how much the canvas width can take, then individually draw the lines on the canvas. Typically, you'll hold the lines in a vector. As for the scrolling part, you need to determine how many lines the canvas can display at a go, and use index shifting to determine what segment of the vector holding the lines should be drawn at any point. You could implement a line shifting or page shifting scrolling mechanism.

Check out this, it solves part 1, part 2 isn't that difficult.
