#' Shiny bindings for lockWidget
#'
#' Output and render functions for using lockWidget within Shiny
#' 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 lockWidget
#' @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 lockWidget-shiny
#'
#' @export
lockWidgetOutput <- function(outputId, width = '100%', height = '400px'){
htmlwidgets::shinyWidgetOutput(outputId, 'lockWidget', width, height, package = 'lockr')
}
#' @rdname lockWidget-shiny
#' @export
renderLockWidget <- function(expr, env = parent.frame(), quoted = FALSE) {
if (!quoted) { expr <- substitute(expr) } # force quoted
htmlwidgets::shinyRenderWidget(expr, lockWidgetOutput, env, quoted = TRUE)
}
