Hi,
I read some time that some window managers creates a
window over the root window and make all the
operations over this created window.
What I want to know is if this operation is a
standard? If it's not, I would suggested that it
became. I really have no idea if it's very difficult,
but it is a important thing for visually impared
people, because if a magnifier is running in split
screen mode a lot of space is lost. So, if all window
managers first create an window, we can adopt a
standard to achieve the ID of this window and have
methods to roll it from under the magnifier when the
pointer goes near the magnifier and the roll it back
when the pointer go far. This way we don't lost
desktop space and the user can have a better spacial
locality.
come again? i don't know what you are getting at in terms of neeeding to mvoe
windows the wm created out of the way for a magnifier etc. and i'm no6t sure
you have a good idea about this "window over root" and what root is
the root window is the first window created by x window system and the
first window created by each client are children of the root window.
this is ok for you?
and how
windows work
why not?
. you need to explain in more detail your issue first. what's the
problem?
Ok, let's try it... if you can, start a GNOME session in your desktop
and do it:
* open a terminal
* type "magnifier -mv" (if you have a complete GNOME installation it
will work)
Now, what you see? A screen that have only a half of useful space. Do
you think that it is good? I know that with composite we can minimize
this problem, but I talk with some user and test other magnifier
applications and a better solution is roll the screen, so the user still
see the non-magnified part and the magnified part. I know too that with
composite we can simulate this roll operation, but the cost will be to high.
If you want to see it working, switch on a window machine and install
Lunar or ZoomText and set these applications to split screen mode and
use for a while the system...
