+\section{\class{wxDragImage}}\label{wxdragimage}
+
+This class is used when you wish to drag an object on the screen,
+and a simple cursor is not enough.
+
+On Windows, the WIN32 API is used to do achieve smooth dragging. On other platforms,
+wxGenericDragImage is used. Applications may also prefer to use
+wxGenericDragImage on Windows, too.
+
+To use this class, when you wish to start dragging an image, create a wxDragImage
+object and store it somewhere you can access it as the drag progresses.
+Call BeginDrag to start, and EndDrag to stop the drag. To move the image,
+initially call Show and then Move. If you wish to update the screen contents
+during the drag (for example, highlight an item as in the dragimag sample), first call Hide,
+update the screen, call Move, and then call Show.
+
+Please see {\tt samples/dragimag} for an example.

+
+Default constructor.
+
+\func{}{wxDragImage}{\param{const wxBitmap\& }{image}, \param{const wxCursor\& }{cursor = wxNullCursor},
+ \param{const wxPoint& }{hotspot = wxPoint(0, 0)}}
+
+Constructs a drag image from a bitmap and optional cursor.
+
+\func{}{wxDragImage}{\param{const wxIcon\& }{image}, \param{const wxCursor\& }{cursor = wxNullCursor},
+ \param{const wxPoint& }{hotspot = wxPoint(0, 0)}}
+
+Constructs a drag image from an icon and optional cursor.
+
+\func{}{wxDragImage}{\param{const wxString\& }{text}, \param{const wxCursor\& }{cursor = wxNullCursor},
+ \param{const wxPoint& }{hotspot = wxPoint(0, 0)}}
+
+Constructs a drag image from a text string and optional cursor.
+
+\func{}{wxDragImage}{\param{const wxTreeCtrl\& }{treeCtrl}, \param{wxTreeItemId\& }{id}}
+
+Constructs a drag image from the text in the given tree control item, and optional cursor.
+
+\func{}{wxDragImage}{\param{const wxListCtrl\& }{treeCtrl}, \param{long }{id}}
+
+Constructs a drag image from the text in the given tree control item, and optional cursor.
+
+\wxheading{Parameters}
+
+\docparam{image}{Icon or bitmap to be used as the drag image. The bitmap can
+have a mask.}
+
+\docparam{text}{Text used to construct a drag image.}
+
+\docparam{cursor}{Optional cursor to combine with the image.}
+
+\docparam{hotspot}{Position of the hotspot within the new image.}
+
+\docparam{treeCtrl}{Tree control for constructing a tree drag image.}
+
+\docparam{listCtrl}{List control for constructing a list drag image.}
+
+\docparam{id}{Tree or list control item id.}
+
+\membersection{wxDragImage::BeginDrag}\label{wxdragimagebegindrag}
+
+\func{bool}{BeginDrag}{\param{const wxPoint\& }{hotspot}, \param{wxWindow* }{window}, \param{bool}{ fullScreen = FALSE}, \param{wxRect*}{ rect = NULL}}
+
+Start dragging the image, in a window or full screen.
+
+\func{bool}{BeginDrag}{\param{const wxPoint\& }{hotspot}, \param{wxWindow* }{window}, \param{wxWindow*}{ boundingWindow}}
+
+Start dragging the image, using the first window to capture the mouse and the second
+to specify the bounding area. This form is equivalent to using the first form,
+but more convenient than working out the bounding rectangle explicitly.
+
+You need to then call \helpref{wxDragImage::Show}{wxdragimageshow} 
+and \helpref{wxDragImage::Move}{wxdragimagemove} to show the image on the screen.
+
+Call \helpref{wxDragImage::EndDrag}{wxdragimageenddrag} when the drag has finished.
+
+Note that this call automatically calls CaptureMouse.
+
+\wxheading{Parameters}
+
+\docparam{hotspot}{The location of the drag position relative to the upper-left corner
+of the image.}
+
+\docparam{window}{The window that captures the mouse, and within which the dragging
+is limited unless {\it fullScreen} is TRUE.}
+
+\docparam{boundingWindow}{In the second form of the function, specifies the
+area within which the drag occurs.}
+
+\docparam{fullScreen}{If TRUE, specifies that the drag will be visible over the full
+screen, or over as much of the screen as is specified by {\it rect}. Note that the mouse will
+still be captured in {\it window}.}
+
+\docparam{rect}{If non-NULL, specifies the rectangle (in screen coordinates) that
+bounds the dragging operation. Specifying this can make the operation more efficient
+by cutting down on the area under consideration, and it can also make a visual difference
+since the drag is clipped to this area.}
+
+{\bf Please note:} full screen dragging only works on Windows at present,
+because on Motif and GTK, the wxScreenDC used to implement full screen dragging only looks at the X root window and not
+the windows on top, when copying from the screen to the backing bitmap.
+Suggestions for solving this one are welcome!
+
+\membersection{wxDragImage::EndDrag}\label{wxdragimageenddrag}
+
+\func{bool}{EndDrag}{\void}
+
+Call this when the drag has finished.
+
+Note that this call automatically calls ReleaseMouse.
+
+\membersection{wxDragImage::Hide}\label{wxdragimagehide}
+
+\func{bool}{Hide}{\void}
+
+Hides the image. You may wish to call this before updating the window
+contents (perhaps highlighting an item). Then call \helpref{wxDragImage::Move}{wxdragimagemove} 
+and \helpref{wxDragImage::Show}{wxdragimageshow}.
+
+\membersection{wxDragImage::Move}\label{wxdragimagemove}
+
+\func{bool}{Move}{\param{const wxPoint\& }{pt}}
+
+Call this to move the image to a new position. The image will only be shown if 
+\helpref{wxDragImage::Show}{wxdragimageshow} has been called previously (for example
+at the start of the drag).
+
+{\it pt} is the position in window coordinates (or screen coordinates if no
+window was specified to BeginDrag.
+
+You can move the image either when the image is hidden or shown, but in general dragging
+will be smoother if you move the image when it is shown.
+
+\membersection{wxDragImage::Show}\label{wxdragimageshow}
+
+\func{bool}{Show}{\void}
+
+Shows the image. Call this at least once when dragging.
