<h2>Detailed Description</h2>
<p>The Q3UriDrag class provides a drag object for a list of URI references.</p>
<p>URIs are a useful way to refer to files that may be distributed across multiple machines. A URI will often refer to a file on a machine local to both the drag source and the drop target, so the URI can be equivalent to passing a file name but is more extensible.</p>
<p>Use URIs in Unicode form so that the user can comfortably edit and view them. For use in HTTP or other protocols, use the correctly escaped ASCII form.</p>
<p>You can convert a list of file names to file URIs using <a href="q3uridrag.html#setFileNames">setFileNames</a>(), or into human-readable form with <a href="q3uridrag.html#setUnicodeUris">setUnicodeUris</a>().</p>
<p>Static functions are provided to convert between filenames and URIs; e.g. <a href="q3uridrag.html#uriToLocalFile">uriToLocalFile</a>() and <a href="q3uridrag.html#localFileToUri">localFileToUri</a>(). Static functions are also provided to convert URIs to and from human-readable form; e.g. <a href="q3uridrag.html#uriToUnicodeUri">uriToUnicodeUri</a>() and <a href="q3uridrag.html#unicodeUriToUri">unicodeUriToUri</a>(). You can also decode URIs from a MIME source into a list with <a href="q3uridrag.html#decodeLocalFiles">decodeLocalFiles</a>() and <a href="q3uridrag.html#decodeToUnicodeUris">decodeToUnicodeUris</a>().</p>
