does anybody know how to change the size and position of the word displayed when using [wordbutton] ?

i think @jshg is talking about http://droidparty.net/

indeed

I don't think it's possible, you can change the font for sure.

Checking the code here : https://github.com/chr15m/PdDroidParty/blob/master/src/cx/mccormick/pddroidparty/Wordbutton.java

at lines 36 and 37, it seems that the text's position is hardcoded at center, and the size is 75% of the widget height.
