XmDropSiteRegister(3X)        SDK X11 R4.11MU05       XmDropSiteRegister(3X)


NAME
       XmDropSiteRegister--A Drag and Drop function that identifies a drop
       site and assigns resources that specify its behavior

SYNOPSIS
       #include <Xm/DragDrop.h>

       void XmDropSiteRegister (widget, arglist, argcount)
            Widget      widget;
            ArgList     arglist;
            Cardinal    argcount;


DESCRIPTION
       XmDropSiteRegister identifies the specified widget or gadget as a
       drop site and sets resource values that define the drop site's
       behavior.  The routine assigns default values to any resources that
       are not specified in the argument list.  The toolkit generates a
       warning message if a drop site is registered with XmNdropSiteActivity
       set to XmDROPSITEACTIVE and the XmNdropProc resource is NULL.

       If the drop site is a descendant of a widget that is registered as a
       drop site, the XmNdropSiteType resource of the ancestor drop site
       must be specified as XmDROPSITECOMPOSITE.  The ancestor must be
       registered before the descendant.  The drop site is stacked above all
       other sibling drop sites already registered.


        widget Specifies the ID of the widget to be registered.

        arglist
               Specifies the argument list.

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