[Sugar-devel] Is it possible to hack the "rotate" key?

[Ajay Garg]

Thanks Gary and Paul.
I tested "Moon" on build 28 on XO-4; and the rotation caused the canvas to
be redrawn appropriately.




Paul,

I have two queries ::

a)
In "Moon"'s code (as already told by Gary), the "size-changed" signal is
used to call the callback that redraws the canvas.
So, in this case, is the "size-changed" signal a result of the
rotate-key-event (KEY_SWITCHVIDEOMODE), or "size-changed" signal is
generated via some another mechanism?

b)
Is the behaviour of olpc-kbdshim the same for a XO-1.75 and a XO-4 (as far
as "that code is written to either run a command
attached to the event (currently /usr/bin/olpc-rotate), or pass the  event
through, but not both" is concerned)?
