< p > The TQMultiLineEdit widget is a simple editor for inputting text.
< p >
< p > The TQMultiLineEdit was a simple editor widget in former TQt versions. TQt
3.0 includes a new richtext engine which obsoletes TQMultiLineEdit. It is
still included for compatibility reasons. It is now a subclass of
< a href = "tqtextedit.html" > TQTextEdit< / a > , and provides enough of the old TQMultiLineEdit API to keep old
applications working.
< p > If you implement something new with TQMultiLineEdit, we suggest using
< a href = "tqtextedit.html" > TQTextEdit< / a > instead and call < a href = "tqtextedit.html#setTextFormat" > TQTextEdit::setTextFormat< / a > (TQt::PlainText).
< p > Although most of the old TQMultiLineEdit API is still available, there is
a few difference. The old TQMultiLineEdit operated on lines, not on
paragraphs. As lines change all the time during wordwrap, the new
richtext engine uses paragraphs as basic elements in the data structure.
All functions (< a href = "#numLines" > numLines< / a > (), < a href = "#textLine" > textLine< / a > (), etc.) that operated on lines, now
operate on paragraphs. Further, getString() has been removed completely.
It revealed too much of the internal data structure.
< p > Applications which made normal and reasonable use of TQMultiLineEdit
should still work without problems. Some odd usage will require some
porting. In these cases, it may be better to use < a href = "tqtextedit.html" > TQTextEdit< / a > now.
