Line Height, Cursor Position and Flickable Issue in TextEdit

[Anonymous Mayank]

Thank you..But how do i move flick line by line of textedit content. Should i consider current position and use line height of content ?

And how to use line-height in TextEdit or TextArea since we do not have that property directly?
Also please tell me how to make flickable scroll to a new line whenever enter is pressed in TextArea?
