I don't really know what dpi is. I suppose it has something to do with pixels
per inch.
Can't you measure screen size with something like getClientRec() and then adjust
all control sizes  based on a ratio of that?
Also isn't wxEuphoria supposed to handle that suff automatically?
I don't have a laptop so I don't have any experiance with different dpis.
I hope this will help some,
