#' applications and interactive Rmd documents.
#'
#' @param outputId output variable to read from
#' @param width,height Must be a valid CSS unit (like \\code{'100\%'},
#' \\code{'400px'}, \\code{'auto'}) or a number, which will be coerced to a
#' string and have \\code{'px'} appended.
#' @param expr An expression that generates a xmltreeview
#' @param env The environment in which to evaluate \\code{expr}.
#' @param quoted Is \\code{expr} a quoted expression (with \\code{quote()})? This
#' is useful if you want to save an expression in a variable.
#'
#' @name xmltreeview-shiny
#'
#' @export
xmltreeviewOutput <- function(outputId, width = '100%', height = '400px'){
htmlwidgets::shinyWidgetOutput(outputId, 'xmltreeview', width, height,
package = 'xmlview')
}
#' @rdname xmltreeview-shiny
#' @export
renderXmltreeview <- function(expr, env = parent.frame(), quoted = FALSE) {
if (!quoted) { expr <- substitute(expr) } # force quoted
htmlwidgets::shinyRenderWidget(expr, xmltreeviewOutput, env, quoted = TRUE)
}
