.nf
#include <Xm/DragDrop\&.h>

.SH "DESCRIPTION"
.PP
\fBXmDropSiteRegister\fP 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 \fBXmNdropSiteActivity\fP set to
\fBXmDROP_SITE_ACTIVE\fP and the \fBXmNdropProc\fP resource
is NULL\&.
.PP
If the drop site is a descendant of a widget that is registered
as a drop site, the \fBXmNdropSiteType\fP resource of the ancestor
drop site must be specified as \fBXmDROP_SITE_COMPOSITE\fP\&. The
ancestor must be registered before the descendant\&. The drop site
is stacked above all other sibling drop sites already registered\&.
.IP "\fIwidget\fP" 10
Specifies the ID of the widget to be registered\&.
.IP "\fIarglist\fP" 10
Specifies the argument list\&.
.IP "\fIargcount\fP" 10
Specifies the number of attribute/value pairs in the argument
list (\fIarglist\fP)\&.
.PP
For a complete definition of DropSite and its associated resources,
