Re: display problem
You should look into the composing image functions available. The beside function should make it so you don't need to calculate exactly where the cursor should be displayed.

We need more context because there's not enough information in the
question to tell what you're trying to do yet.
Good luck!
taking the image for the left side text, and take its width?
Where I see a problem is here :
I start with this :
aaaaa|
now someone press 3 times the left key.
So I have aa/aaa
How can I know where the cursor is now.
Or can I do width - 3 times 11 ?
