In The following code, the table handler is executed twice when the
button is pressed (from the 2nd pressing on).
I want it to be executed only once. Does someone know, why this
happens and how I can change it?
library(gWidgets)
w <- gwindow()
b <- gbutton("press", cont=w)
tbl <- gtable(1:10, cont=w)
addhandlerclicked(b, handler=function(h, ...){
cat("addhandlerclicked button\n")
svalue(tbl, index=T) <- 1 # change the table
value
})
addhandlerclicked(tbl, handler=function(h, ...){
cat("addhandlerclicked table\n")
})
Thanks!
Mark
