Original GitHub issue: https://github.com/rivo/tview/issues/547

Taking the List "hello world" example and adding a SetTitle call to it:

package main

import (
	"github.com/rivo/tview"
)

func main() {
	app := tview.NewApplication()
	list := tview.NewList().
		AddItem("List item 1", "Some explanatory text", 'a', nil).
		AddItem("List item 2", "Some explanatory text", 'b', nil).
		AddItem("List item 3", "Some explanatory text", 'c', nil).
		AddItem("List item 4", "Some explanatory text", 'd', nil).
		AddItem("Quit", "Press to exit", 'q', func() {
			app.Stop()
		}).SetTitle("Borked")
	if err := app.SetRoot(list, true).EnableMouse(true).Run(); err != nil {
		panic(err)
	}
}

will not render anything to the console.

SetTitle() is a function of Box and it returns an instance of Box. So your list variable actually points to a box, and this is what gets drawn. It has no border, thus no title, so nothing gets drawn.

If you want to add a title, put the SetTitle() call in a separate line:

list.SetTitle("Borked")
