Description Rich Burridge 2006-10-04 15:59:58 UTC 
See Orca bug #355524 for more background.

I will be attaching two files to this bug:

1/ bug_355524.py - a standalone Python script that replicates
   the problem.
2/ bug_355524.out - the results of running bug_355524.py.

Steps to reproduce:

1. Run gnome-about
2. Run gnome-terminal
3. Run the attached standalone python application in an xterm
4. Click on the gnome-terminal window.  Press F11.
5. Click on the gnome-about window.  Press F11.

Actual Results:
Step 4: You will see what a well-behaved application should do.
Step 5: You will see output like the following with the following
        values: (start=0, end=51, x=0, y=0, width=0, height=0)

Expected Results:
getRangeExtents should produce values that are real

Comment 3 padraig.obriain 2006-11-14 13:56:59 UTC 
The problem is that atk_get_range_extents is not working for GailCanvasText.

The reason is that the function gail_canvas_text_get_character_extents exists but
does nothing.

Move to libgnomecanvas since A11Y support of libgnomecanvas has been moved here.

BTW, does anyone know how to get the coordinate of a given char_offset for GnomeCanvasText?

You can query it using the PangoLayout* of the GnomeCanvasText, adjust it by the ink-rect (or logical rect) that is also stored in the text item and everything should work like a charm.

Methinks someone fixed something somewhere. Orca is now doing the right thing, Rich's script is now giving valid numbers.

I'll leave it to someone else to close this out since I didn't fix it. ;-)

Closing this based on the last comment.
