# findWrapPos

`open static fun findWrapPos(text: String, width: Int, startPos: Int): Int`

Finds the next text wrap position after `startPos` for the text in `text` with the column width `width`. The wrap point is the last position before startPos+width having a whitespace character (space, \n, \r). If there is no whitespace character before startPos+width, it will return startPos+width.

### Parameters

`text` - The text being searched for the wrap position

`width` - width of the wrapped text

`startPos` - position from which to start the lookup whitespace character

Return
position on which the text must be wrapped or -1 if the wrap position is at the end of the text
