Is it true that the stock FXCanvas doesn't support tooltips, but we can 
get around that with a subclass of FXCanvas:

	require 'fox'
	require 'fox/responder'

	include Fox

	class TooltipCanvas < FXCanvas

	  include Responder

	  attr_accessor :tipText

	  def initialize(*args)
	    # Initialize base class
	    super

	    # Default tooltip
	    self.tipText = "Canvas"

	    # Listen for query messages from the tooltip
	    FXMAPFUNC(SEL_UPDATE, FXWindow::ID_QUERY_TIP, :onQueryTip)
	  end

	  def onQueryTip(sender, sel, ptr)
	    sender.text = tipText
	    return 1
	  end
	end

You should be able to use this one in place of a normal canvas, and set 
its tooltip message with the tipText accessor.

Hope this helps,
