<h2>Detailed Description</h2>
|
|
<p>The Q3TextDrag class is a drag and drop object for transferring plain and Unicode text.</p>
|
|
<p>Plain text is passed in a <a href="qstring.html">QString</a> which may contain multiple lines (i.e. may contain newline characters). The drag target will receive the newlines according to the runtime environment, e.g. LF on Unix, and CRLF on Windows.</p>
|
|
<p>Qt provides no built-in mechanism for delivering only a single-line.</p>
|
|
<p>For more information about drag and drop, see the <a href="q3dragobject.html">Q3DragObject</a> class and the <a href="dnd.html">drag and drop documentation</a>.</p>
