The QMultiLineEdit widget is a simple editor for inputting text.
The QMultiLineEdit was a simple editor widget in former Qt versions. Qt 3.0 includes a new richtext engine which obsoletes QMultiLineEdit. It is still included for compatibility reasons. It is now a subclass of QTextEdit, and provides enough of the old QMultiLineEdit API to keep old applications working.
If you implement something new with QMultiLineEdit, we suggest using QTextEdit instead and call QTextEdit::setTextFormat(Qt::PlainText).
Although most of the old QMultiLineEdit API is still available, there is a few difference. The old QMultiLineEdit 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 (numLines(), textLine(), etc.) that operated on lines, now operate on paragraphs. Further, getString() has been removed completely. It revealed too much of the internal data structure.
Applications which made normal and reasonable use of QMultiLineEdit should still work without problems. Some odd usage will require some porting. In these cases, it may be better to use QTextEdit now.

bool QMultiLineEdit::hasMarkedText | ( | ) | const |
Returns TRUE if there is selected text.
void QMultiLineEdit::home | ( | bool | mark = FALSE | ) | [protected, virtual] |
Moves the text cursor to the left end of the line. If mark is TRUE, text is selected toward the first position. If it is FALSE and the cursor is moved, all selected text is unselected.
virtual void QMultiLineEdit::home | ( | bool | mark = FALSE | ) | [protected, virtual] |
Inserts str at the current cursor position and selects the text if mark is TRUE.
Reimplementado de QTextEdit.
virtual void QMultiLineEdit::insertAt | ( | const QString & | text, |
int | para, | ||
int | index | ||
) | [inline, virtual] |

Reimplementado de QTextEdit.
Inserts string s at paragraph number line, after character number col in the paragraph. If s contains newline characters, new lines are inserted. If mark is TRUE the inserted string will be selected.
The cursor position is adjusted.
Inserts txt at paragraph number line. If line is less than zero, or larger than the number of paragraphs, the new text is put at the end. If txt contains newline characters, several paragraphs are inserted.
The cursor position is not changed.

This is the same as QTextEdit's "modifed" property.
int QMultiLineEdit::numLines [read] |
the number of paragraphs in the editor
The count includes any empty paragraph at top and bottom, so for an empty editor this method returns 1.
