Removing event handler? #92

Closed Kugelschieber closed 5 years ago

Kugelschieber commented 8 years ago

Is it possible to remove event handlers? I can't find a way to remove them.

mikepea commented 8 years ago

I had a similar problem, and seem to have got what I needed via setting the handler func to be empty:

func deregisterEventHandlers() {
   ui.Handle("/sys/kbd/", func(ev ui.Event) {})
   ui.Handle("/sys/kbd/C-c", func(ev ui.Event) {})
   ui.Handle("/sys/wnd/resize", func(ev ui.Event) {})
}

If you're shelling out, you will also need to enable echo and opost (at least) on the tty:

stty := exec.Command("stty", "-f", "/dev/tty", "echo", "opost")
_ = stty.Run()

(& re-enable and re-render afterwards)

I'm still not 100% this is the 'right' way, but can't see another way of doing it without a PR onto nsf/termbox-go

I solved it by adding a function to remove handlers to termui directly. But I wanted to know if there is a "right" way of doing it already. I may create a pull request, but the author doesn't seem to do much for a month.

Closing this as events have been reworked so there is no longer any event handlers, but let me know if you still have any issues.
