Re: Getting the character at certain position...

[ChCarver]

This question has spawned me to ask. Is there a way to gather the current
terminal contents from the shell when an application starts? When I start my
ncurses application and paint (for the lack of a better term) with a new
window the contents of the terminal are removed and when I exit the contents
of the terminal come back. So it's that shell terminal contents I want.

I'd like to add to Speedy, I use a character buffer that allows me to scroll
through a window. It's the same concept video game developers use in
creating off screen buffers. That way I can create a virtual terminal as
large as I want it, mainly this allows me to scroll left or scroll right
inside a window. Whenever I want to read a character a call into the buffer
returns what I'm looking for. Only a section of the buffer of coarse is
displayed. But then I don't have to keep track of certain aspects. For me I
allow the user to "bookmark" (once again lack of a better term) a row. Then
they can scroll through bookmarks in the buffer and ncurses allows me to
repaint the windows really fast. I don't know if this might help, but it
might give you future ideas.
