@cindex xwidget-view type
An @dfn{xwidget} is a special display element, such as a web
browser, that can be embedded inside a buffer. Each window that
displays an xwidget will also have an @dfn{xwidget view}, which on
X-Windows corresponds to a single X window used to display the widget.
Neither of these objects are readable; their print syntaxes look like
@samp{#<xwidget>} and @samp{#<xwidget-view>}, respectively.
