Hi list,
I've been sketching out an application and could do with a little
advice on which cocoa-direction to take. It's a full-screen (kiosk)
type app, running in a very controlled environment (not for wide
release) but which would run on an external touchscreen monitor.
While I can make buttons and labels big enough for fingers to poke,
I'm concerned about controls like table headers and scrollers being
large enough to make finger-size targets. I'm asking sooner rather
than after testing the usability in case there are special
considerations I should take before writing the first lines of code.
The only options I can think of are:
1. Make a normal app and use quartz debug to scale *everything* up
2. Subclass and/or redraw any controls too small for finger taps
3. Shut up and try it out first
In the absence of UIKit for desktop macs, does anyone have any
suggestions as to the direction an app like this should take?
Thanks,
Ben
