ginput: input dialog.

In jverzani/gWidgetsWWW2: Toolkit implementation of the gWidgets API for use with web pages

Description

Used for getting a text string to pass to a handler. Unlike other gWidgets implementations, this call does not block the R process, so any response to the user must be done through the handler.

Usage

ginput(message, text = "", title = "Input", icon = NULL, parent = NULL,
  handler = NULL, action = NULL, ...)

Arguments

message	message
text	initial text for the widget
title	title for dialog's window
icon	icon ignored here
parent	parent container (main window instance)
handler	Called if yes is selected, the component input of the first argument holds the user-supplied string.
action	passed to any handler
...	ignored

Value

return value ignored, use handler for response

Examples

w <- gwindow()
gbutton("click me for a message", cont=w, handler=function(h,...) {
  ginput("What is your name?", parent=w, handler=function(h,...) {
    galert(paste("Hello", h$input), parent=w)
  })
})
