Equivalent function

hi,
There is a function in Qt 3.3.4 for QTextEdit like:
te->text(int line)
which returns the text at "line". What is its equivalent function in Qt 4.0.1

Also tell me the equivalent function for :
1) "te->paragraphs()" which gives the no.of paragraphs in the textedit.
2) "te->setSelection(int parafrom ,int indexfrom ,int parato ,int indexto)"

Thanks & regards,
Sarma.

kindly mention any url where I can have the comparisions between the old methods and the newer ones that I have to use.
