Colors change when creating a new screen

[Bios-Marcel]

Hey,

so I've found a very weird behaviour when creating a new screen. Seemingly, the initially created screen honours the terminal colours, while the second screen doesn't. I've written a little demo to show this:

package main

import "github.com/gdamore/tcell"

var style = tcell.StyleDefault.Background(tcell.ColorBlack).Foreground(tcell.ColorRed)

func main() {
	screenShow()
}

func screenShow() {
	screenA, err := tcell.NewScreen()
	if err != nil {
		panic(err)
	}
	err = screenA.Init()
	if err != nil {
		panic(err)
	}

	screenA.Fill('A', style)
	screenA.Show()

	//Wait one event
LOOP:
	for {

		switch event := screenA.PollEvent().(type) {
		case *tcell.EventKey:
			if event.Key() == tcell.KeyESC || event.Key() == tcell.KeyCtrlC {
				break LOOP
			}
			if event.Key() == tcell.KeyEnter {
				screenA.Fini()
				screenShow()
			}
		default:
			continue
		}
	}

	screenA.Fini()
}

Simply run it an hit enter. I am currently running termite, in case that matters.

Here's a gif, in case it doesn't work for you:

Yeah I think recalling Init and Fini is problematic. These were never designed for this kind of usage. I will need to investigate making this more robust.

[Bios-Marcel]

Yeah, the easy way to workaround this, is trying to reuse screen I guess, but I thought I'd report this either way. Maybe something that can be fixed at some point in v2 🤷 It's not really that problematic.

Please see master, which now has Suspend() and Resume() APIs. Hopefully that will be superior to using Init and Fini for this purpose.

I'm going to close this now.
