We strongly advise against using it in new code. +<p> The QMultiLineEdit widget is a simple editor for inputting text. +<p> +<p> 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 +<a href="qtextedit.html">QTextEdit</a>, and provides enough of the old QMultiLineEdit API to keep old +applications working. +<p> If you implement something new with QMultiLineEdit, we suggest using +<a href="qtextedit.html">QTextEdit</a> instead and call <a href="qtextedit.html#setTextFormat">QTextEdit::setTextFormat</a>(Qt::PlainText). +<p> 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 (<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 QMultiLineEdit +should still work without problems. Some odd usage will require some +porting. In these cases, it may be better to use <a href="qtextedit.html">QTextEdit</a> now. +<p> <img src=qmlined-m.png> <img src=qmlined-w.png> +<p> <p>See also <a href="qtextedit.html">QTextEdit</a> and <a href="advanced.html">Advanced Widgets</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QMultiLineEdit"></a>QMultiLineEdit::QMultiLineEdit ( <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 ) +</h3> +Constructs a new, empty, QMultiLineEdit with parent <em>parent</em> called +<em>name</em>. + +<h3 class=fn>int <a name="alignment"></a>QMultiLineEdit::alignment () const +</h3><p>Returns the editor's paragraph alignment. +See the <a href="qmultilineedit.html#alignment-prop">"alignment"</a> property for details. +<h3 class=fn>bool <a name="atBeginning"></a>QMultiLineEdit::atBeginning () const +</h3><p>Returns TRUE if the cursor is placed at the beginning of the text; otherwise returns FALSE. +See the <a href="qmultilineedit.html#atBeginning-prop">"atBeginning"</a> property for details. +<h3 class=fn>bool <a name="atEnd"></a>QMultiLineEdit::atEnd () const +</h3><p>Returns TRUE if the cursor is placed at the end of the text; otherwise returns FALSE. +See the <a href="qmultilineedit.html#atEnd-prop">"atEnd"</a> property for details. +<h3 class=fn>bool <a name="autoUpdate"></a>QMultiLineEdit::autoUpdate () const +</h3> + +<b>This function is obsolete.</b> It is provided to keep old source working.
