NAME

       XmDropSiteRegister  —  A  Drag  and  Drop function that identifies a drop site and assigns
       resources that  specify  its  behavior  "XmDropSiteRegister"  "Drag  and  Drop  functions"
       "XmDropSiteRegister" "register functions" "XmDropSiteRegister"

SYNOPSIS

       #include <Xm/DragDrop.h>
       void XmDropSiteRegister(
       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
       XmDROP_SITE_ACTIVE 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
       XmDROP_SITE_COMPOSITE.  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).

       For a complete definition of DropSite and its associated resources, see XmDropSite(3).
