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