how to activate to previous application

Kindleschokolade · 12-29-2021, 01:36 PM

Hello,
i am making extensive use of eips within a python script to write data to the screen.
Now when I am done with the script I would like to go reactivate whatever was on the screen before.
For example I had kual open but after my script the screen is just blank.
when I touch the screen where a kual button is, kual reactivates,.
How can I achieve that from a script?

Thanks

cat /dev/fb0 > screen.dump

do stuff

cat screen.dump > /dev/fb0

<whatever eips flag does a simple refresh> (or fbink -s -f).

(There's an example of this in the ScreenSavers KUAL extension for the preview option. Also, probably in the KOReader startup script, IIRC).

Can also be handled via FBInk in a prettier way for API users via the fbink_dump/fbink_restore set of calls.
