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

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