如何在 radioGroupButtons 的按钮之间获得更多 space 并包含图标

How to get more space between buttons of radioGroupButtons and to include icons

我正在使用带有选项 individual = TRUE 的 shinyWidgets 包的 'radioGroupButtons'。按钮紧密并排放置。

我有两个问题。 是否可以在按钮之间获得更多 space? 是否也可以让按钮标签前面有一个图标(Glyphicon、Font Awesome)?

如果是这样就好了:

我的代码如下:

library(shiny)
library(shinyjs)
library(shinyWidgets)

ui <- fluidPage(
  useShinyjs(),

  radioGroupButtons(
    inputId = "id000",
    label = NULL,
    choices = c("Text",  "File", "Web"),
    individual = TRUE,
    selected = character(0))
)

server <- function(input, output, session)
{
  observeEvent(input$id000, alert(input$id000), ignoreInit = TRUE)
}

shinyApp(ui = ui, server = server)

这应该有效:

library(shiny)
library(shinyjs)
library(shinyWidgets)

ui <- fluidPage(
  useShinyjs(),
  tags$head(tags$style('.btn-group{ margin-left: 15px;}')),  # add the spacing
  icon(NULL),  # need a call to icon to attach some dependencies; probably a better solution exists
  radioGroupButtons(
    inputId = "id000",
    label = NULL,
    choices = c(`<i class='fas fa-font'></i> Text` = "Text",
                `<i class='far fa-file-alt'></i> File` = "File", 
                `<i class='fas fa-globe-americas'></i> Web` = "Web"),
    individual = TRUE,
    selected = character(0))
)

server <- function(input, output, session)
{
  observeEvent(input$id000, alert(input$id000), ignoreInit = TRUE)
}

shinyApp(ui = ui, server = server)
