#include <Q3UriDrag>This class is part of the Qt 3 support library. It is provided to keep old source code working. We strongly advise against using it in new code. See Porting to Qt 4 for more information.

The Q3UriDrag class provides a drag object for a list of URI references.
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.
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.
You can convert a list of file names to file URIs using setFileNames(), or into human-readable form with setUnicodeUris().
Static functions are provided to convert between filenames and URIs; e.g. uriToLocalFile() and localFileToUri(). Static functions are also provided to convert URIs to and from human-readable form; e.g. uriToUnicodeUri() and unicodeUriToUri(). You can also decode URIs from a MIME source into a list with decodeLocalFiles() and decodeToUnicodeUris().
Constructs an object to drag the list of uris. The dragSource and name are passed to the Q3StoredDrag constructor.
Note that URIs are always in escaped UTF8 encoding.
Constructs an object to drag with the given name. You must call setUris() before you start the drag(). Both the dragSource and the name are passed to the Q3StoredDrag constructor.
Destroys the URI drag object.
Returns true if decode() can decode the MIME source; otherwise returns false.
Decodes URIs from the MIME source, placing the result in the list. The list is cleared before any items are inserted.
Returns true if the MIME source contained a valid list of URIs; otherwise returns false.
Decodes URIs from the MIME source, converting them to local filenames where possible, and places them in the list (which is first cleared).
Returns true if the MIME source contained a valid list of URIs; otherwise returns false. The list will be empty if no URIs referred to local files.
Decodes URIs from the MIME source, converting them to Unicode URIs (only useful for displaying to humans), and places them in the list (which is first cleared).
Returns true if the MIME source contained a valid list of URIs; otherwise returns false.
Returns the URI equivalent to the absolute local filename.
See also uriToLocalFile().
Sets the URIs to be local file URIs equivalent to the filenames.
See also localFileToUri() and setUris().
Same as setFileNames(QStringList(name)).
Same as setFileNames(QStringList(name)).
Sets the URIs in the list to be Unicode URIs (only useful for displaying to humans).
See also localFileToUri() and setUris().
Changes the list of URIs to be dragged.
Note that URIs are always in escaped UTF8 encoding.
Returns the URI equivalent of the Unicode URI given in the string (only useful for displaying to humans).
See also uriToLocalFile().
Returns the name of a local file equivalent to the URI given in the string, or an empty string if it does not refer to a local file.
Note that URIs are always in escaped UTF8 encoding.
See also localFileToUri().
Returns the Unicode URI (only useful for displaying to humans) equivalent of the URI given in the string.
Note that URIs are always in escaped UTF8 encoding.
See also localFileToUri().
