rerender tcltk toplevel
...)
tclvalue(prog) <- i*2
}
When I combine both approaches and add the label to a toplevel that
already contains the progress bar updating the label works:
tt <-tktoplevel()
tkwm.geometry(tt, "250x140")
prog <- tclVar("0")
label <- tklabel(tt, textvariable=prog)
progBar <- tkwidget(tt, "ProgressBar", variable=prog)
tclRequire("BWidget")
tkgrid(progBar)
tkgrid(label)
for(i in 1:50) {
tmp <- rnorm(1e+05)
tclvalue(prog) <- i*2
}
Is there a way to explicitly rerender a tcltk toplevel? There must be
one since the ProgressBar widge...
