DESCRIPTION
The QUriDrag 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-readble form with setUnicodeUris().
Static functions are provided to convert between filenames and URIs,
e.g. uriToLocalFile() and localFileToUri(), and to and from human-
readable form, e.g. uriToUnicodeUri(), unicodeUriToUri(). You can also
decode URIs from a mimesource into a list with decodeLocalFiles() and
decodeToUnicodeUris().
See also Drag And Drop Classes.
MEMBER FUNCTION DOCUMENTATIONQUriDrag::QUriDrag ( QStrList uris, QWidget * dragSource = 0, const char *
name = 0 )
Constructs an object to drag the list of URIs in uris. The dragSource
and name arguments are passed on to QStoredDrag. Note that URIs are
always in escaped UTF8 encoding.
QUriDrag::QUriDrag ( QWidget * dragSource = 0, const char * name = 0 )
Constructs an object to drag. You must call setUris() before you start
the drag(). Passes dragSource and name to the QStoredDrag constructor.
QUriDrag::~QUriDrag ()
Destroys the object.
bool QUriDrag::canDecode ( const QMimeSource * e ) [static]
Returns TRUE if decode() would be able to decode e; otherwise returns
FALSE.
bool QUriDrag::decode ( const QMimeSource * e, QStrList & l ) [static]
Decodes URIs from e, placing the result in l (which is first cleared).
Returns TRUE if e contained a valid list of URIs; otherwise returns
FALSE.
Example: dirview/dirview.cpp.
bool QUriDrag::decodeLocalFiles ( const QMimeSource * e, QStringList & l )
[static]
Decodes URIs from the mime source event e, converts them to local files
if they refer to local files, and places them in l (which is first
cleared).
Returns TRUE if contained a valid list of URIs; otherwise returns
FALSE. The list will be empty if no URIs were local files.
Example: fileiconview/qfileiconview.cpp.
bool QUriDrag::decodeToUnicodeUris ( const QMimeSource * e, QStringList & l )
[static]
Decodes URIs from the mime source event e, converts them to Unicode
URIs (only useful for displaying to humans), placing them in l (which
is first cleared).
Returns TRUE if contained a valid list of URIs; otherwise returns
FALSE.
QCString QUriDrag::localFileToUri ( const QString & filename ) [static]
Returns the URI equivalent to the absolute local file filename.
See also uriToLocalFile().
void QUriDrag::setFileNames ( const QStringList & fnames )
Sets the URIs to be the local-file URIs equivalent to fnames.
See also localFileToUri() and setUris().
Example: dirview/dirview.cpp.
void QUriDrag::setFilenames ( const QStringList & fnames )
This function is obsolete. It is provided to keep old source working.
We strongly advise against using it in new code.
Use setFileNames() instead (notice the N).
void QUriDrag::setUnicodeUris ( const QStringList & uuris )
Sets the URIs in uuris to be the Unicode URIs (only useful for
displaying to humans).
See also localFileToUri() and setUris().
void QUriDrag::setUris ( QStrList uris ) [virtual]
Changes the list of uris to be dragged.
Note that URIs are always in escaped UTF8 encoding.
QCString QUriDrag::unicodeUriToUri ( const QString & uuri ) [static]
Returns the URI equivalent of the Unicode URI given in uuri (only
useful for displaying to humans).
See also uriToLocalFile().
QString QUriDrag::uriToLocalFile ( const char * uri ) [static]
Returns the name of a local file equivalent to uri or a null string if
uri is not a local file.
Note that URIs are always in escaped UTF8 encoding.
See also localFileToUri().
Example: dirview/dirview.cpp.
QString QUriDrag::uriToUnicodeUri ( const char * uri ) [static]
Returns the Unicode URI (only useful for displaying to humans)
equivalent of uri.
Note that URIs are always in escaped UTF8 encoding.
See also localFileToUri().
