.SH "SYNOPSIS"

.PP

.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,

see \fBXmDropSite\fP(3)\&.
