Thanks to you both.
I've read both posts (and will need to read them again as I implement them -- probably more than once). The designer scripts feature seems very useful. I had been doing something similar in the actual program with an initialization sub, but its not as flesible as the designer scripts seem to be.
A question I have about the scripts is can I use a "standard" layout file? That is, the principle layout I've created is for a 4.3 inch screen with a resolution of 480 X 800. Can I use that and use a script to do the scaling?
Also, with one of the apps, I want the layout to fill the screen for small screens, but only fill the center of the screen on larger devices. Can I do that with designer scripts or should I make that variation from within the main code? Do designer scripts support If...Then and Select statements?
Thanks.
