Extracing values of gedit in gbasicdialog

Question

I am trying to create a interface where the user can key in a number for the script to run. However, I am unable to retrieve the value keyed into gedit. Can anyone help me? Here's what I have done:

require(gWidgets2RGtk2) #Load package
w=gbasicdialog("key number")
a<-gedit("1",cont=w,handler=function(h,...){number<-svalue(a)})
visible(w)=TRUE

Here I create , 2 gedit and update the value of one with the other value using a button:

w <- gwindow("test")
g <- ggroup(cont=w, horizontal=FALSE)
x <- gedit("20",cont=g)
gbutton("changevalue",cont=g,handler=function(h,...) {
  svalue(e) <- svalue(x)
})
e <- gedit("", cont=g)

enter image description here

Is it possible for me to do this without adding a button? – Wet Feet Jan 21 '14 at 09:18

You have addHandlerKeystroke that is called when values in the `gedit` box are updated by typing. – jverzani Feb 01 '14 at 13:54

What I have done here is the same as suggested by jverzani

require(gWidgets2RGtk2) #Load package
 w = gbasicdialog("key number")
 a <- gedit("1",cont=w)
 addHandlerKeystroke(a, handler=function(h,..) { 

    number <- svalue(a)
    print(number)
 })
 visible(w)=TRUE
