	)
	window.SetContent(widget.NewVScrollContainer(grid))

	window.ShowAndRun()

}

func files() []fyne.CanvasObject {
	objects := make([]fyne.CanvasObject, 100)
	for i := range objects {
		text := widget.NewLabel(strconv.Itoa(i))
		text.Wrapping = fyne.TextTruncate
		text.Alignment = fyne.TextAlignCenter

		objects[i] = fyne.NewContainerWithLayout(
