## Not run: ## These cannot be run by examples() but should be OK when pasted ## into an interactive R session with the tcltk package loaded ## Using plain Tcl/Tk label and button (tk2XXX equivalent have built-in ## tooltip features) tt2 <- tktoplevel() lb <- tklabel(tt2, text = "Move mouse over me, or over the button to see tooltip") tkgrid(lb) tk2tip(lb, "A tooltip for the label \ndisplayed on two lines") but <- tkbutton(tt2, text = "Exit", width = 10, command = function() tkdestroy(tt2)) tkgrid(but) tk2tip(but, "Exit from this dialog box") ## To test tk2killtip(), move mouse on top of a widget ## so that the tip is visible, and force killing it manually using: tk2killtip() ## Move again to the widget: the tip is displayed again. ## End(Not run)
