# 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.
