Original GitHub issue: https://github.com/rivo/tview/issues/650

I've found that when a button/form is added as an item to a tview.Newflex layout the actions will not trigger. Examples:

package main

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

func main() {
	app := tview.NewApplication()
	form := tview.NewForm().
		AddDropDown("Title", []string{"Mr.", "Ms.", "Mrs.", "Dr.", "Prof."}, 0, nil).
		AddInputField("First name", "", 20, nil, nil).
		AddInputField("Last name", "", 20, nil, nil).
		AddCheckbox("Age 18+", false, nil).
		AddPasswordField("Password", "", 10, '*', nil).
		AddButton("Save", nil).
		AddButton("Quit", func() {
			app.Stop()
		})
	form.SetBorder(true).SetTitle("Enter some data").SetTitleAlign(tview.AlignLeft)

	flex := tview.NewFlex().
		AddItem(tview.NewBox().SetBorder(true).SetTitle("Left Side"), 0, 1, false).
		AddItem(tview.NewFlex().SetDirection(tview.FlexRow).
			AddItem(form, 16, 2, false).
			AddItem(tview.NewBox().SetBorder(true).SetTitle("Bottom Pane"), 0, 1, false), 0, 3, false)

	if err := app.SetRoot(flex, true).Run(); err != nil {
		panic(err)
	}
}

@rivo commented on GitHub (Sep 27, 2021):

If you enable the mouse, your example code works:

if err := app.SetRoot(flex, true).EnableMouse(true).Run(); err != nil {
	panic(err)
}

Closing since this was what was missing.
