3 | This class represents a source for a drag and drop operation. | |
4 | ||
5 | See \helpref{Drag'n'Drop overview}{wxdndoverview} and \helpref{wxDataObject overview}{wxdataobjectoverview} | |
6 | for more information. | |

17 | ||
18 | \index{wxDragResult}wxDragResult is defined as follows: | |
19 | ||
20 | {\small\begin{verbatim} | |
21 | enum wxDragResult | |
22 | { | |
23 | wxDragError, // error prevented the d&d operation from completing | |
24 | wxDragNone, // drag target didn't accept the data | |
25 | wxDragCopy, // the data was successfully copied | |
26 | wxDragMove, // the data was successfully moved | |
27 | wxDragCancel // the operation was cancelled by user (not an error) | |
28 | }; | |
29 | \end{verbatim} | |

41 | \func{}{wxDropSource}{\param{wxWindow*}{ win = NULL}} | |
42 | ||
43 | Default/wxGTK-specific constructor. If you use the default constructor you must | |
44 | call \helpref{SetData}{wxdropsourcesetdata} later. | |
45 | ||
46 | Note that {\it win} is required by the GTK port and therefore should always be set. | |
47 | ||
48 | \membersection{wxDropSource::\destruct{wxDropSource}}\label{wxdropsourcedtor} | |
49 | ||
50 | \func{virtual }{\destruct{wxDropSource}}{\void} | |
51 | ||
52 | \membersection{wxDropSource::SetData}\label{wxdropsourcesetdata} | |
53 | ||
54 | \func{void}{SetData}{\param{wxDataObject\&}{ data}} | |
55 | ||
56 | Sets the data \helpref{wxDataObject}{wxdataobject} associated with the | |
57 | drop source. This will not delete any previously associated data. | |
58 | ||
59 | \membersection{wxDropSource::DoDragDrop}\label{wxdropsourcedodragdrop} | |
60 | ||
61 | \func{virtual wxDragResult}{DoDragDrop}{\param{bool }{allowMove = FALSE}} | |
62 | ||
63 | Do it (call this in response to a mouse button press, for example). | |
64 | ||
65 | If {\bf allowMove} is FALSE, data can only be copied. | |
66 | ||
67 | \membersection{wxDropSource::GiveFeedback}\label{wxdropsourcegivefeedback} | |
68 | ||
69 | \func{virtual bool}{GiveFeedback}{\param{wxDragResult }{effect}, \param{bool }{scrolling}} | |
70 | ||
71 | Overridable: you may give some custom UI feedback during the drag and drop operation | |
72 | in this function. It is called on each mouse move, so your implementation must not be too | |
73 | slow. | |
74 | ||
75 | \wxheading{Parameters} | |
76 | ||
77 | \docparam{effect}{The effect to implement. One of wxDragCopy, wxDragMove and wxDragNone. } | |
78 | ||
79 | \docparam{scrolling}{TRUE if the window is scrolling. MSW only. } | |
80 | ||
81 | \wxheading{Return value} | |
82 | ||
83 | Return FALSE if you want default feedback, or TRUE if you implement your own | |
84 | feedback. The return values is ignored under GTK. | |
