Index out of range error for label, sometimes...

[jpecor]

I am getting an index out of range error from the button_3 code in the example:

button_3 = Button(x=BUTTON_MARGIN*3+2*BUTTON_WIDTH, y=BUTTON_MARGIN*2+BUTTON_HEIGHT, width=BUTTON_WIDTH, height=BUTTON_HEIGHT, label="button3", label_font=font, label_color=0x0000FF, fill_color=None, outline_color=None) buttons.append(button_3)

Here's the error:

Traceback (most recent call last): File "code.py", line 71, in <module> File "adafruit_button.py", line 127, in __init__ File "adafruit_button.py", line 140, in label IndexError: Group index out of range

After tinkering a bit with the code, I found that if I pass in a value for EITHER the fill_color OR outline_color, it works. So, for example, this works:

button_3 = Button(x=BUTTON_MARGIN*3+2*BUTTON_WIDTH, y=BUTTON_MARGIN*2+BUTTON_HEIGHT, width=BUTTON_WIDTH, height=BUTTON_HEIGHT, label="button3", label_font=font, label_color=0x0000FF, fill_color=0x00FF00, outline_color=None) buttons.append(button_3)

I have not dug into this any deeper, yet, but wanted to post the issue in case it's more obvious to someone else.

I get very similar errors. If the outline_color is 0x0 or None, it errors:

File "adafruit_button.py", line 136, in __init__
File "adafruit_button.py", line 149, in label
IndexError: Group index out of range

But if outline_color is 0xFF0000 for example, it's fine.
