< p > The TQTextDrag class is a drag and drop object for
transferring plain and Unicode text.
< p >
< p > Plain text is passed in a < a href = "tqstring.html" > TQString< / a > which may contain multiple lines
(i.e. may contain newline characters). The drag target will receive
the newlines according to the runtime environment, e.g. LF on Unix,
and CRLF on Windows.
< p > TQt provides no built-in mechanism for delivering only a single-line.
< p > For more information about drag and drop, see the < a href = "tqdragobject.html" > TQDragObject< / a > class
and the < a href = "dnd.html" > drag and drop documentation< / a > .
< p > See also < a href = "draganddrop.html" > Drag And Drop Classes< / a > .

< h3 class = fn > < a name = "TQTextDrag" > < / a > TQTextDrag::TQTextDrag ( const < a href = "tqstring.html" > TQString< / a > & text, < a href = "tqwidget.html" > TQWidget< / a > * dragSource = 0, const char * name = 0 )
< / h3 >
Constructs a text drag object and sets its data to < em > text< / em > . < em > dragSource< / em > must be the drag source; < em > name< / em > is the object name.
< h3 class = fn > < a name = "TQTextDrag-2" > < / a > TQTextDrag::TQTextDrag ( < a href = "tqwidget.html" > TQWidget< / a > * dragSource = 0, const char * name = 0 )
< / h3 >
Constructs a default text drag object. < em > dragSource< / em > must be the
drag source; < em > name< / em > is the object name.
< h3 class = fn > < a name = "~TQTextDrag" > < / a > TQTextDrag::~TQTextDrag ()
< / h3 >
Destroys the text drag object and frees up all allocated
resources.
< h3 class = fn > bool < a name = "canDecode" > < / a > TQTextDrag::canDecode ( const < a href = "tqmimesource.html" > TQMimeSource< / a > * e )< tt > [static]< / tt >
< / h3 >
Returns TRUE if the information in < em > e< / em > can be decoded into a
< a href = "tqstring.html" > TQString< / a > ; otherwise returns FALSE.
< p > < p > See also < a href = "#decode" > decode< / a > ().
< p > Example: < a href = "simple_dd-example.html#x2827" > iconview/simple_dd/main.cpp< / a > .

< / h3 >
Attempts to decode the dropped information in < em > e< / em > into < em > str< / em > .
Returns TRUE if successful; otherwise returns FALSE.
< p > < p > See also < a href = "#canDecode" > canDecode< / a > ().
< p > Example: < a href = "simple_dd-example.html#x2828" > iconview/simple_dd/main.cpp< / a > .
< h3 class = fn > bool < a name = "decode-2" > < / a > TQTextDrag::decode ( const < a href = "tqmimesource.html" > TQMimeSource< / a > * e, < a href = "tqstring.html" > TQString< / a > & str, < a href = "tqcstring.html" > TQCString< / a > & subtype )< tt > [static]< / tt >
< / h3 >
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
< p > Attempts to decode the dropped information in < em > e< / em > into < em > str< / em > .
Returns TRUE if successful; otherwise returns FALSE. If < em > subtype< / em >
is null, any text subtype is accepted; otherwise only the
specified < em > subtype< / em > is accepted.
< p > < p > See also < a href = "#canDecode" > canDecode< / a > ().
< h3 class = fn > void < a name = "setSubtype" > < / a > TQTextDrag::setSubtype ( const < a href = "tqcstring.html" > TQCString< / a > & st )< tt > [virtual]< / tt >
< / h3 >
Sets the MIME subtype of the text being dragged to < em > st< / em > . The
default subtype is "plain", so the default MIME type of the text
is "text/plain". You might use this to declare that the text is
"text/html" by calling < a href = "#setSubtype" > setSubtype< / a > ("html").
< h3 class = fn > void < a name = "setText" > < / a > TQTextDrag::setText ( const < a href = "tqstring.html" > TQString< / a > & text )< tt > [virtual]< / tt >
< / h3 >
Sets the text to be dragged to < em > text< / em > . You will need to call this
if you did not pass the text during construction.
