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 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).
