Hi
Kindly correct me if I am posting a wrong query in the forum.
I am trying to handle my "button:clicked" event. But not able to
proceed
further. Please help.
Following is my code:
library(RGtk2)
win <- gtkWindowNew(type = NULL, show = TRUE)
butt <- gtkButtonNewWithLabel("Submit", show = TRUE)
win$Add(butt)
Now I want to do something when my button is clicked. How can I grab the
"clicked" signal and define actions against it?
Thanks in advance.

Sarthi,
See help(gSignalConnect) for instructions on how to connect to GObject
signals.
For this particular case, try gSignalConnect(butt, "clicked",
function(wid)
print("clicked!")).
See the demos included in the RGtk2 paper for numerous examples of using
gSignalConnect().
