function on.paint(gc)
if message then
gc:setFont("sansserif", "r", 10) -- initialize font drawing
gc:drawString(message, 0, 0, "top") -- display the message at (0, 0) coordinates
message = nil -- erase the message
timer.start(1) -- start a timer to exit on.paint() but keep in mind that we have to redraw the screen
end
end
function on.timer()
timer.stop()
platform.window:invalidate()
end
function on.charIn(ch)
message = "Hello World !" -- store a message
