bitmap_label does not show text if not initialized with something.

[FoamyGuy]

bitmap_label will not draw text if it's set after creation instead of passing text in the constructor

import board
import terminalio
from adafruit_display_text import bitmap_label
from adafruit_display_text import label

text = "Hello world"
# text_area = label.Label(terminalio.FONT, max_glyphs=50)  # regular label does show the text afterward.

text_area = bitmap_label.Label(terminalio.FONT)
# text_area = bitmap_label.Label(terminalio.FONT, text=" ") # if we init with a space it will show the text
text_area.text = text
text_area.x = 10
text_area.y = 10
board.DISPLAY.show(text_area)
while True:
    pass

I can take a look into making the bitmap_label work the same as label in this scenario. Also am curious if @kmatch98 have any ideas if you have a chance to take a look.

what board is this, magtag? you have to force a refresh if so

[FoamyGuy]

@ladyada PyPortal and UM Feather S2 with 128x32 OLED. Still waiting for delivery on magtag

[kmatch98]

Let me try it on the PyPortal and see what’s going on.

This was a bug that was introduced when the separate self and self.local_group was added to handle modifying the scaling on the fly.

The bug was when the text was "" and it actually was modifying the self group rather than the self.local_group. Pull request is incoming.
