How to change paragraph number in QTextEdit?

[jacek]

That means, if the capacity of the visible region of the textedit is 10 lines, at any time(even when scrollbar is dragged to middle of a large file) the variable para1 is holding the values from 1-10 because of which, the variable "line" is taking only those lines.

As the docs say:

int QTextEdit::paragraphAt ( const QPoint & pos ) const
Returns the paragraph which is at position pos (in contents coordinates).

You must first translate your mouse position (which is in vieport coordinates) to contents coordinates. Use QScrollView::viewportToContents() method.

hi jacek,
Its working man. Thanks a lot. So, I have added the following step at line5:

clickPos=te->viewportToContents(clickPos);

clickPos=te->viewportToContents(clickPos);

To copy to clipboard, switch view to plain text mode 

regards,
Sarma.
