VTE library utilizes tree tables to insert terminal capability strings.
The VTE library, or libvte as it is commonly referred to, includes a wrapper application (vte) that is housed in a GTK window. While all settings are hard-coded to whatever was needed for testing, the library still works well in practice. However, for those who need more in-depth functionality, I would recommend using the gnome-terminal instead.
So, how does it work? The VTE library inserts terminal capability strings into a tree of tables, which allows it to determine if incoming data is a control sequence or just random data. The sample program "interpret" can give you a better understanding of what the widget sees after it filters incoming data.
All in all, I would highly recommend giving the VTE library a try. It is well-designed, efficient, and functions as intended.
