[maemo-developers] Disable auto uppercase on input?

[From: Till Harbaum / Lists]

Hi,

i know that this auto uppercase for the first letter can be disabled in the control panel.
But how do i disable this from my program? There are e.g. gtkentry fields used to enter
a password in osm2go and i already had users that were going mad entering their 
passwords (with all characters replaced by *'s, so no visual feedback) until they
realized that maemo made the first char upper case.

There are other entry widgets where i know that entering uppercase isn't useful. So
ho can i disable this withiut asking the user to change his global control panel
settings?
