Dynamic screen during application execution ?

Hi David,

Thanks very much for your response. For sure I'm interested to see what you have done.

My stack is available here : http://revonline2.runrev.com/stack/469/Mobile-Template-for-IPhone-IPad-Android

My goal is to give a template to developers for the basic part of an application on mobile devices,
more I could implement in the template, less the developers have to think about basic architecture and
could focus on their business part.

In the actual version, I have one sub-stack per device and I concentrate all code in the main stack,
like that for sub-stack you just call command and function from main stack. This solution seems
correct, but at the end you have to design your screen for each kind of device, with the risk of mistake.

It's why I was thinking about 1 sub-stack only, and just design the screen on the fly when the program
is executed, I though with this solution, you have less chance to do a mistake, and for the specific
part I will just use "Switch, Case". The only bad thing is that you don't have a real screen available
for developing, you have to put objects on the right place during execution and so...

It's also why I search someone who has already experimented this kind of feature, I received absolutely
no feedback from others about my template, and I'm not sure if it could help someone or not ...

Cheers, Fabrice
