The drag target will receive the newlines according to the runtime environment, e.g. LF on Unix, and CRLF on Windows. <p> TQt provides no built-in mechanism for delivering only a single-line. <p> For more information about drag and drop, see the <a href="ntqdragobject.html">TQDragObject</a> class and the <a href="dnd.html">drag and drop documentation</a>. <p>See also <a href="draganddrop.html">Drag And Drop Classes</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="TQTextDrag"></a>TQTextDrag::TQTextDrag ( const <a href="ntqstring.html">TQString</a> & text, <a href="ntqwidget.html">TQWidget</a> * dragSource = 0, const char * name = 0 ) </h3> Constructs a text drag object and sets its data to <em>text</em>. <em>dragSource</em> must be the drag source; <em>name</em> is the object name. <h3 class=fn><a name="TQTextDrag-2"></a>TQTextDrag::TQTextDrag ( <a href="ntqwidget.html">TQWidget</a> * dragSource = 0, const char * name = 0 ) </h3> Constructs a default text drag object. <em>dragSource</em> must be the drag source; <em>name</em> is the object name. <h3 class=fn><a name="~TQTextDrag"></a>TQTextDrag::~TQTextDrag () </h3> Destroys the text drag object and frees up all allocated resources. <h3 class=fn>bool <a name="canDecode"></a>TQTextDrag::canDecode ( const <a href="qmimesource.html">TQMimeSource</a> * e )<tt> [static]</tt> </h3> Returns TRUE if the information in <em>e</em> can be decoded into a <a href="ntqstring.html">TQString</a>; otherwise returns FALSE. <p> <p>See also <a href="#decode">decode</a>(). <p>Example: <a href="simple_dd-example.html#x2827">iconview/simple_dd/main.cpp</a>. <h3 class=fn>bool <a name="decode"></a>TQTextDrag::decode ( const <a href="qmimesource.html">TQMimeSource</a> * e, <a href="ntqstring.html">TQString</a> & str )<tt> [static]</tt> </h3> Attempts to decode the dropped information in <em>e</em> into <em>str</em>.

The default subtype is "plain", so the default MIME type of the text is "text/plain".
