I'm sorry, I know this is idiotically obvious, but I can't seem to get the two DropBox scripts to run properly.

dropbox_login runs fine, the app keys and such are accepted

DropboxSync stops at

client = dropboxlogin.get_client()

I get

ErrorResponse: [403]:u"Invalid app key (consumer key)....."

Any thoughts?

I'm fairly new to programming (since my old TRS-80 days!), so this may be obvious.

I'm trying to put text onto a button. I have two problems.

1. The text is always oriented to the bottom-left, and I don't see a way to shift it relative to the frame;

2. The new layered button suddenly doesn't do anything, though I haven't changed the code for touch_began.

The following example includes lots of stuff to demonstrate what does and doesn't work, and where I got it. The problem is in class TextBtn, which will appear in the top left of the screen if you run this.

Code:

from scene import *
from random import random   # unnecessary for this, but I didn't bother cutting it'

A passing note:

LandyQuack's code also generates a dead space, visually blank, SW of multiples like ButtonBar. If you make ButtonBar generate last in the main MyApp (Scene) sequence, and move it up and right, you'll see a white space appear SW of the line of 5 buttons.

Anyone know why this happens? It's a dead space, and ideally we don't want to be using space on the screen that isn't good for something.
