Thanks Egmont

The application is for an assisted speech device for disabled children. I will need to control everything, what OS, which font, which terminal and even which monitor but I think it can be done and if it fails a text only environment will still work. I would just like to make it useful for very young children that cannot recognize sight words.

Have a great day

$WINDOWID might be what you're looking for.

Note that whatever you do, it'll probably be an ugly hack that just happens to work with your favorite terminal at a hardcoded font size.  E.g. how would your X app figure out the terminal's font size?

Also, keep in mind that there are terminals that have multiple tabs and your one might not be the visible one (e.g. gnome-terminal -- also beware that it's known in gnome-terminal that if you drag-n-drop a tab to another gnome-terminal window then $WINDOWID becomes incorrect because it can't be updated); there are terminals with split screen feature (e.g. gnome terminator) and then how do you figure out the offset; etc...

Hi Everyone !

I have been tinkering around with xwininfo and wmctrl but I was wondering if there was a better way to get the ID of the window that an ncurses application was running it?

With a little xcb I think I can write images to an ncurses application. I think I could allocate a given X Y space and just write around that space with ncurses.
