Sie möchten also einige spezifische Klassen zu Ihrem radioGroupButtons
hinzufügen. Nun, ShinyWidgets lässt Sie nicht, also warum nicht Ihre eigene radioButtons
Widget-Funktion erstellen.
Hint (Na ja, wird diese Funktion fast ausschließlich aus radioGroupButtons
kopiert werden): Typ radioGroupButton
in die R
Konsole den Quellcode anzuzeigen.
Und lassen Sie diese Funktion so optimieren, dass sie ein class
Argument akzeptiert, das auf das html
Element angewendet wird. Dann können Sie einfach mit Ihrem CSS auf die verschiedenen radioGroupButton
-Klassen zugreifen.
Arbeits Code unten:
library("shinyWidgets")
library(shiny)
# Defining the new Widget.
customRadioGroupButtons <- function (inputId, label = NULL, choices, selected = NULL, status = "default", size = "normal", direction = "horizontal", justified = FALSE, individual = FALSE, checkIcon = list(), class=NULL) {
choices <- shinyWidgets:::choicesWithNames(choices)
if (!is.null(selected) && length(selected) > 1)
stop("selected must be length 1")
if (is.null(selected))
selected <- choices[1]
size <- match.arg(arg = size, choices = c("xs", "sm", "normal",
"lg"))
direction <- match.arg(arg = direction, choices = c("horizontal",
"vertical"))
status <- match.arg(arg = status, choices = c("default",
"primary", "success", "info", "warning", "danger"))
divClass <- if (individual)
""
else "btn-group"
if (!individual & direction == "vertical") {
divClass <- paste0(divClass, "-vertical")
}
if (justified) {
divClass <- paste(divClass, "btn-group-justified")

if (size != "normal") {
divClass <- paste0(divClass, " btn-group-", size)

# Below here, the paste call is the only difference to the original function.

Das ist eine gute Idee, den Benutzer eine benutzerdefinierte Klasse übergeben zu lassen, ich werde es in das Paket implementieren implementieren. – Victorp
