|
|---|
| 55 |
|
|---|
| 56 |
|
|---|
| 57 | <p> The QTextDrag class is a drag and drop object for
|
|---|
| 58 | transferring plain and Unicode text.
|
|---|
| 59 | <p>
|
|---|
| 60 | <p> Plain text is passed in a <a href="qstring.html">QString</a> which may contain multiple lines
|
|---|
| 61 | (i.e. may contain newline characters). The drag target will receive
|
|---|
| 62 | the newlines according to the runtime environment, e.g. LF on Unix,
|
|---|
| 63 | and CRLF on Windows.
|
|---|
| 64 | <p> Qt provides no built-in mechanism for delivering only a single-line.
|
|---|
| 65 | <p> For more information about drag and drop, see the <a href="qdragobject.html">QDragObject</a> class
|
|---|
| 66 | and the <a href="dnd.html">drag and drop documentation</a>.
|
|---|
| 67 | <p>See also <a href="draganddrop.html">Drag And Drop Classes</a>.

| 70 | <h3 class=fn><a name="QTextDrag"></a>QTextDrag::QTextDrag ( const <a href="qstring.html">QString</a> & text, <a href="qwidget.html">QWidget</a> * dragSource = 0, const char * name = 0 )
|
|---|
| 71 | </h3>
|
|---|
| 72 | 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.
|
|---|
| 73 |
|
|---|
| 74 | <h3 class=fn><a name="QTextDrag-2"></a>QTextDrag::QTextDrag ( <a href="qwidget.html">QWidget</a> * dragSource = 0, const char * name = 0 )
|
|---|
| 75 | </h3>
|
|---|
| 76 | Constructs a default text drag object. <em>dragSource</em> must be the
|
|---|
| 77 | drag source; <em>name</em> is the object name.
|
|---|
| 78 |
|
|---|
| 79 | <h3 class=fn><a name="~QTextDrag"></a>QTextDrag::~QTextDrag ()
|
|---|
| 80 | </h3>
|
|---|
| 81 | Destroys the text drag object and frees up all allocated
|
|---|
| 82 | resources.
|
|---|
| 83 |
|
|---|
| 84 | <h3 class=fn>bool <a name="canDecode"></a>QTextDrag::canDecode ( const <a href="qmimesource.html">QMimeSource</a> * e )<tt> [static]</tt>
|
|---|
| 85 | </h3>
|
|---|
| 86 | Returns TRUE if the information in <em>e</em> can be decoded into a
|
|---|
| 87 | <a href="qstring.html">QString</a>; otherwise returns FALSE.
|
|---|
| 88 | <p> <p>See also <a href="#decode">decode</a>().
|
|---|
| 89 |
|
|---|
| 90 | <p>Example: <a href="simple_dd-example.html#x2827">iconview/simple_dd/main.cpp</a>.
|
|---|
| 91 | <h3 class=fn>bool <a name="decode"></a>QTextDrag::decode ( const <a href="qmimesource.html">QMimeSource</a> * e, <a href="qstring.html">QString</a> & str )<tt> [static]</tt>
|
|---|
| 92 | </h3>
|
|---|
| 93 | Attempts to decode the dropped information in <em>e</em> into <em>str</em>.
|
|---|
| 94 | Returns TRUE if successful; otherwise returns FALSE.
|
|---|
| 95 | <p> <p>See also <a href="#canDecode">canDecode</a>().
|
|---|
| 96 |
|
|---|
| 97 | <p>Example: <a href="simple_dd-example.html#x2828">iconview/simple_dd/main.cpp</a>.
|
|---|
| 98 | <h3 class=fn>bool <a name="decode-2"></a>QTextDrag::decode ( const <a href="qmimesource.html">QMimeSource</a> * e, <a href="qstring.html">QString</a> & str, <a href="qcstring.html">QCString</a> & subtype )<tt> [static]</tt>
|
|---|
| 99 | </h3>
|
|---|
| 100 | This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|---|
| 101 | <p> Attempts to decode the dropped information in <em>e</em> into <em>str</em>.
|
|---|
| 102 | Returns TRUE if successful; otherwise returns FALSE. If <em>subtype</em>
|
|---|
| 103 | is null, any text subtype is accepted; otherwise only the
|
|---|
| 104 | specified <em>subtype</em> is accepted.
|
|---|
| 105 | <p> <p>See also <a href="#canDecode">canDecode</a>().
|
|---|
| 106 |
|
|---|
| 107 | <h3 class=fn>void <a name="setSubtype"></a>QTextDrag::setSubtype ( const <a href="qcstring.html">QCString</a> & st )<tt> [virtual]</tt>
|
|---|
| 108 | </h3>
|
|---|
| 109 | Sets the MIME subtype of the text being dragged to <em>st</em>. The
|
|---|
| 110 | default subtype is "plain", so the default MIME type of the text
|
|---|
| 111 | is "text/plain". You might use this to declare that the text is
|
|---|
| 112 | "text/html" by calling <a href="#setSubtype">setSubtype</a>("html").
|
|---|
| 113 |
|
|---|
| 114 | <h3 class=fn>void <a name="setText"></a>QTextDrag::setText ( const <a href="qstring.html">QString</a> & text )<tt> [virtual]</tt>
|
|---|
| 115 | </h3>
|
|---|
| 116 | Sets the text to be dragged to <em>text</em>. You will need to call this
|
|---|
| 117 | if you did not pass the text during construction.
