29 The QTextDrag class is a drag and drop object for transferring plain
30 and Unicode text.
31 Plain text is passed in a QString which may contain multiple lines
33 (i.e. may contain newline characters). The drag target will receive the
34 newlines according to the runtime environment, e.g. LF on Unix, and
35 CRLF on Windows.
36 Qt provides no built-in mechanism for delivering only a single-line.
38 For more information about drag and drop, see the QDragObject class and
40 the drag and drop documentation.
41 See also Drag And Drop Classes.
43
46 char * name = 0 )
47 Constructs a text drag object and sets its data to text. dragSource
48 must be the drag source; name is the object name.
49
51 Constructs a default text drag object. dragSource must be the drag
52 source; name is the object name.
53
55 Destroys the text drag object and frees up all allocated resources.
56
58 Returns TRUE if the information in e can be decoded into a QString;
59 otherwise returns FALSE.
60 See also decode().
62 Example: iconview/simple_dd/main.cpp.
64
66 Attempts to decode the dropped information in e into str. Returns TRUE
67 if successful; otherwise returns FALSE.
68 See also canDecode().
70 Example: iconview/simple_dd/main.cpp.
72
74 subtype ) [static]
75 This is an overloaded member function, provided for convenience. It
76 behaves essentially like the above function.
77 Attempts to decode the dropped information in e into str. Returns TRUE
79 if successful; otherwise returns FALSE. If subtype is null, any text
80 subtype is accepted; otherwise only the specified subtype is accepted.
81 See also canDecode().
83
85 Sets the MIME subtype of the text being dragged to st. The default
86 subtype is "plain", so the default MIME type of the text is
87 "text/plain". You might use this to declare that the text is"
88 text/html" by calling setSubtype("html").
89
91 Sets the text to be dragged to text. You will need to call this if you
92 did not pass the text during construction.
