NAME

       XmGetDragContext -- A Drag and Drop function that retrieves the DragContext widget ID associated with a timestamp

SYNOPSIS

       #include <Xm/DragC.h>
       Widget XmGetDragContext(
       Widget refwidget,
       Time timestamp);

DESCRIPTION

       XmGetDragContext  returns the widget ID of the active DragContext associated with a given display and timestamp. A timestamp uniquely iden-
       tifies which DragContext is active when more than one drag and drop transaction has been initiated on a display. If the specified timestamp
       matches	a  timestamp  processed between the start and finish of a single drag and drop transaction, the function returns the corresponding
       DragContext ID.

       refwidget Specifies the ID of the widget that the routine uses to identify the intended display. The function returns the ID of	the  Drag-
		 Context associated with the display value passed by this widget.

       timestamp Specifies a timestamp.

       For a complete definition of DragContext and its associated resources, see XmDragContext(3).

RETURN

       Returns	the  ID  of the DragContext widget that is active for the specified timestamp. Otherwise, returns NULL if no active DragContext is
       found.

NAME

       XmDragStart -- A Drag and Drop function that initiates a drag and drop transaction

SYNOPSIS

       #include <Xm/DragDrop.h>
       Widget XmDragStart(
       Widget widget,
       XEvent *event,
       ArgList arglist,
       Cardinal argcount);

DESCRIPTION

       XmDragStart  initiates  a  drag operation. This routine returns the DragContext widget that it initializes for the associated drag transac-
       tion. The toolkit is responsible for freeing the DragContext when the drag and drop transaction is complete.

       widget	 Specifies the ID of the smallest widget and/or gadget that encloses the source elements selected for a drag operation.

       event	 Specifies the XEvent that triggered the drag operation. This event must be a ButtonPress event.

       arglist	 Specifies the argument list. Any XmDragContext resources not specified in the argument list are obtained from the resource  data-
		 base or are set to their default values.

       argcount  Specifies the number of attribute/value pairs in the argument list (arglist)

       For a complete definition of DragContext and its associated resources, see XmDragContext(3).

RETURN

       Returns the ID of the DragContext widget that controls this drag and drop transaction.  Returns NULL if the drag cannot be initiated.
