Hi all,
I would like to propose a few additions to ATK and AT-SPI:
- In atk, the size and position of a window can be get or set. Gail
already has code implementing this for gtk widgets, but the functionality
is currently not exposed over at-spi; there are methods to get the
extents, size, and position of a window but no corresponding method to set
them. I propose to add setSize, setPosition, and setExtents methods
to the at-spi Component interface. The GAIL implementation of set_extents
only affects top-level windows; it does nothing for all other widgets.
I also propose to add an atk function with the following prototype if no
one objects / people think it makes sense:
gpointer atk_object_get_native_window_handle (AtkObject *accessible);
This would return a handle from the native windowing system for the given
object, if available. It may return NULL.
I have had a discussion with someone who is working on porting a macro
language from Windows and requested this functionality. Apparently it is
possible with this package to change the title of a window, for instance,
and this can be done under Windows but not through AT-SPI under Linux.
Both of these additions would also help for the AT-SPI-to-UIA bridge,
since UI Automation exposes functionality corresponding to what I am
describing. I am not really sure what I think of the
get_native_window_handle bit, since it would allow a program to do things
other than what an end user could do, so I am not sure if there are
security implications. Perhaps similar functionality is already available
through X, though, in which case I don't think it would create significant
security issues beyond what is already there.
Does anyone have any thoughts?
Thanks,
-Mike G-
