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?
It sounds like a problem positioning the text. Maybe in your code or in
GooCanvasTable.
If you want to send me a test app I'll have a look at it.
Actually since everything else in the table seems to be painting OK, I'd
guess it is either a problem with your code, or with the toy text API.
Maybe try using Pango instead.
