The TQUriDrag 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 > 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 > You can convert a list of file names to file URIs using
< a href = "#setFileNames" > setFileNames< / a > (), or into human-readble form with < a href = "#setUnicodeUris" > setUnicodeUris< / a > ().
< p > Static functions are provided to convert between filenames and
URIs, e.g. < a href = "#uriToLocalFile" > uriToLocalFile< / a > () and < a href = "#localFileToUri" > localFileToUri< / a > (), and to and from
human-readable form, e.g. < a href = "#uriToUnicodeUri" > uriToUnicodeUri< / a > (), < a href = "#unicodeUriToUri" > unicodeUriToUri< / a > ().
You can also decode URIs from a mimesource into a list with
< a href = "#decodeLocalFiles" > decodeLocalFiles< / a > () and < a href = "#decodeToUnicodeUris" > decodeToUnicodeUris< / a > ().

< h3 class = fn > < a name = "TQUriDrag" > < / a > TQUriDrag::TQUriDrag ( < a href = "ntqstrlist.html" > TQStrList< / a > uris, < a href = "tqwidget.html" > TQWidget< / a > * dragSource = 0, const char * name = 0 )
< / h3 >
Constructs an object to drag the list of URIs in < em > uris< / em > . The < em > dragSource< / em > and < em > name< / em > arguments are passed on to < a href = "qstoreddrag.html" > TQStoredDrag< / a > .
Note that URIs are always in escaped UTF8 encoding.
< h3 class = fn > < a name = "TQUriDrag-2" > < / a > TQUriDrag::TQUriDrag ( < a href = "tqwidget.html" > TQWidget< / a > * dragSource = 0, const char * name = 0 )
< / h3 >
Constructs an object to drag. You must call < a href = "#setUris" > setUris< / a > () before you
start the < a href = "ntqdragobject.html#drag" > drag< / a > (). Passes < em > dragSource< / em > and < em > name< / em > to the
< a href = "qstoreddrag.html" > TQStoredDrag< / a > constructor.
< h3 class = fn > < a name = "~TQUriDrag" > < / a > TQUriDrag::~TQUriDrag ()
< / h3 >
Destroys the object.
< h3 class = fn > bool < a name = "canDecode" > < / a > TQUriDrag::canDecode ( const < a href = "qmimesource.html" > TQMimeSource< / a > * e )< tt > [static]< / tt >
< / h3 >
Returns TRUE if < a href = "#decode" > decode< / a > () would be able to decode < em > e< / em > ; otherwise
returns FALSE.
< h3 class = fn > bool < a name = "decode" > < / a > TQUriDrag::decode ( const < a href = "qmimesource.html" > TQMimeSource< / a > * e, < a href = "ntqstrlist.html" > TQStrList< / a > & l )< tt > [static]< / tt >
< / h3 >
Decodes URIs from < em > e< / em > , placing the result in < em > l< / em > (which is first
cleared).
< p > Returns TRUE if < em > e< / em > contained a valid list of URIs; otherwise
returns FALSE.
< p > Example: < a href = "dirview-example.html#x1707" > dirview/dirview.cpp< / a > .
< h3 class = fn > bool < a name = "decodeLocalFiles" > < / a > TQUriDrag::decodeLocalFiles ( const < a href = "qmimesource.html" > TQMimeSource< / a > * e, < a href = "ntqstringlist.html" > TQStringList< / a > & l )< tt > [static]< / tt >
< / h3 >
Decodes URIs from the mime source event < em > e< / em > , converts them to
local files if they refer to local files, and places them in < em > l< / em >
(which is first cleared).
< p > Returns TRUE if < em > contained< / em > a valid list of URIs; otherwise
returns FALSE. The list will be empty if no URIs were local files.
< p > Example: < a href = "fileiconview-example.html#x873" > fileiconview/qfileiconview.cpp< / a > .
< h3 class = fn > bool < a name = "decodeToUnicodeUris" > < / a > TQUriDrag::decodeToUnicodeUris ( const < a href = "qmimesource.html" > TQMimeSource< / a > * e, < a href = "ntqstringlist.html" > TQStringList< / a > & l )< tt > [static]< / tt >
< / h3 >
Decodes URIs from the mime source event < em > e< / em > , converts them to
Unicode URIs (only useful for displaying to humans), placing them
in < em > l< / em > (which is first cleared).
< p > Returns TRUE if < em > contained< / em > a valid list of URIs; otherwise
returns FALSE.
< h3 class = fn > < a href = "ntqcstring.html" > TQCString< / a > < a name = "localFileToUri" > < / a > TQUriDrag::localFileToUri ( const < a href = "ntqstring.html" > TQString< / a > & filename )< tt > [static]< / tt >
< / h3 >
Returns the URI equivalent to the absolute local file < em > filename< / em > .
< p > < p > See also < a href = "#uriToLocalFile" > uriToLocalFile< / a > ().
< h3 class = fn > void < a name = "setFileNames" > < / a > TQUriDrag::setFileNames ( const < a href = "ntqstringlist.html" > TQStringList< / a > & fnames )
< / h3 >
Sets the URIs to be the local-file URIs equivalent to < em > fnames< / em > .
< p > < p > See also < a href = "#localFileToUri" > localFileToUri< / a > () and < a href = "#setUris" > setUris< / a > ().

< / h3 >
< b > This function is obsolete.< / b > It is provided to keep old source working. We strongly advise against using it in new code.
< p > Use < a href = "#setFileNames" > setFileNames< / a > () instead (notice the N).
< h3 class = fn > void < a name = "setUnicodeUris" > < / a > TQUriDrag::setUnicodeUris ( const < a href = "ntqstringlist.html" > TQStringList< / a > & uuris )
< / h3 >
Sets the URIs in < em > uuris< / em > to be the Unicode URIs (only useful for
displaying to humans).
< p > < p > See also < a href = "#localFileToUri" > localFileToUri< / a > () and < a href = "#setUris" > setUris< / a > ().
