- Classes: #wxDataObject,
- #wxTextDataObject,
- #wxDropSource,
- #wxDropTarget,
- #wxTextDropTarget,
- #wxFileDropTarget
- Note that wxUSE_DRAG_AND_DROP must be defined in setup.h in order
- to use drag and drop in wxWidgets.
- See also: @ref dataobject_overview and @ref samplednd_overview
- It may be noted that data transfer to and from the clipboard is quite
- similar to data transfer with drag and drop and the code to implement
- these two types is almost the same. In particular, both data transfer
- mechanisms store data in some kind of #wxDataObject
- and identify its format(s) using the #wxDataFormat
- class.
- To be a @e drag source, i.e. to provide the data which may be dragged by
- the user elsewhere, you should implement the following steps:
-
-
-  @b Preparation: First of all, a data object must be created and
- initialized with the data you wish to drag. For example:
-
- @code
- wxTextDataObject my_data("This text will be dragged.");
- @endcode
-
- @b Drag start: To start the dragging process (typically in response to a
- mouse click) you must call wxDropSource::DoDragDrop
- like this:
-
- @code
- wxDropSource dragSource( this );
-  dragSource.SetData( my_data );
-  wxDragResult result = dragSource.DoDragDrop( TRUE );
- @endcode
-
-  @b Dragging: The call to DoDragDrop() blocks the program until the user releases the
- mouse button (unless you override the #GiveFeedback function
- to do something special). When the mouse moves in a window of a program which understands the
- same drag-and-drop protocol (any program under Windows or any program supporting the
- XDnD protocol under X Windows), the corresponding #wxDropTarget methods
- are called - see below.
-  @b Processing the result: DoDragDrop() returns an @e effect code which
- is one of the values of @c wxDragResult enum (explained #here):
-
- @code
- switch (result)
-  {
-      case wxDragCopy: /* copy the data */ break;
-case wxDragMove: /* move the data */
-break;
-default:         /* do nothing */
-break;

+to use drag and drop in wxWidgets.

+To be a @e drag source, i.e. to provide the data which may be dragged by

+
+@li @b Preparation: First of all, a data object must be created and
+    initialized with the data you wish to drag. For example:
+
+    @code
+    wxTextDataObject my_data("This text will be dragged.");
+    @endcode
 
+@li <b>Drag start</b>: To start the dragging process (typically in response to a
+    mouse click) you must call wxDropSource::DoDragDrop like this:
 
-@b Initialization: For a window to be a drop target, it needs to have
-an associated #wxDropTarget object. Normally, you will
-call wxWindow::SetDropTarget during window
-creation associating your drop target with it. You must derive a class from
-            wxDropTarget and override its pure virtual methods. Alternatively, you may
-            derive from #wxTextDropTarget or
-#wxFileDropTarget and override their OnDropText()
-            or OnDropFiles() method.
-            @b Drop: When the user releases the mouse over a window, wxWidgets
-            asks the associated wxDropTarget object if it accepts the data. For this,
-            a #wxDataObject must be associated with the drop target
-            and this data object will be responsible for the format negotiation between
-                the drag source and the drop target. If all goes well, then #OnData
-                will get called and the wxDataObject belonging to the drop target can get
-                filled with data.
-                @b The end: After processing the data, DoDragDrop() returns either
-                    wxDragCopy or wxDragMove depending on the state of the keys Ctrl, Shift
-                    and Alt at the moment of the drop. There is currently no way for the drop
-                    target to change this return code.
