Unable to update scrolling_label text outside constructor

[VinceVega7]

Hi,

It seems that you can not update the text of a scrolling_label outside the constructor.
If outside the constructor but before the showing the display, if I update it to "test" it still retains "Hello World"

eg.

import displayio
import terminalio
import time
from adafruit_matrixportal.matrix import Matrix
from adafruit_display_text.scrolling_label import ScrollingLabel

matrix = Matrix()
display = matrix.display


# setup the label
font = terminalio.FONT
splash = displayio.Group()

title_label = ScrollingLabel(
    text="Hello World", font=font, color=0xFFFFFF, scale=1,
    anchored_position=(0, 0), anchor_point=(0, 0),
)

#### Here this does not work
title_label.text = "test"

splash.append(title_label)
display.show(splash)

while True:

   title_label.update()

Hi :), you could use

title_label.full_text = "Changing the Text"

Hoping this is what you need!

Jposada is correct about full_text being the intended way to update the text on a ScrollingLabel.

However it was written that way initially moreso because I didn't know how to correctly override the parent property and still make the rest of the code work properly.

After thinking on it a bit I do think it would be ideal if text property could be used though because just like @VinceVega7 was expecting I think average user is going to assume it will change out the entire text since that is how it behaves for the other label types.

I've created #188 to override it so that the API functionality now matches more closely.
