Core widgets
TermPty
The TermPty widget spawns a new process and connects it to a pty. It automatically handles the pty's input and output, forwarding all events it receives to the inner process.
Scroll events
Because there's no way to know whether scroll events are meant for the top-level application or its nested child, scroll events performed on top of the pty widget will always be forwarded to the nested process, and will thus not affect the top-level application.
Process management functions
spawn(fileName: string, args: string[]): void
Spawns a new process and connects it to a pty. The fileName argument is the name of the executable to run, and the args argument is an array of strings to pass as arguments to the executable.
