spurious text

[Richard Gipps <rgipps netspace net au>]

Hi,
   I have created several of my own Canvas Items which are based very 
heavily on GooCanvasRectModel. I have used these items in a 
GooCanvasTable. I recently added some text to these canvas items using 
the "Toy" text API in Cairo and functions such as  cairo_show_text(). 
This worked well and would render as I expected.  The problem comes when 
one moves the mouse over/into the table items containing the text. When 
this happens some spurious text is rendered outside the table area. This 
problem is best illustrated using the picture I have attached. The R1 to 
the far left is the spurious text. I have drawn rectangles around the 
canvas items for clarity.

One can cover the canvas and expose it again and this text "disappears" 
but as soon as the mouse is moved over the canvas item the spurious text 
is drawn again.

Anyone have any ideas?

Regards,
Richard.
