Hi all,
How can I get current line text from QTextEdit?
Also, How can I get current line number and count of lines in component?

send me email
and I'll dig it up.

Oh... try to use QTextCursor and found that it is solution for me. Complete
example below:
---- cut here ----
QTextCursor cursor = fontfileEdit->textCursor();
// Current line text
QString cur_line_text = cursor.block().text().trimmed();
// Current line
int cur_line_number = cursor.blockNumber();
// Current column
int cur_line_column = cursor.columnNumber();
---- cut here ----
But I have one question, this functionality was added in QT 4.2 (as sayed in
documentation), but, how I can realise it on more older QT versions (4.1, 4.0)?
