Hello,

My application has to handle configuration data for some machine types. Some 
machines are programmable graphically, some by config dialogs. The data gets 
compiled and uploaded to the machine. Of course future machine types will 
require new dialogs or enhanced graphical programming features.

My customer would prefer to have the same file extension for all machine types. 
File type would be decided by file internal header (some magic bytecode). 
Regarding file internal representation, we are still flexible.

Machines can be grouped in projects. Project files (they just contain file 
names etc. of machines, no machine configs) have separate file extension and 
file format. The project handling exists as prototype. Now I think about the 
cooperation with the a2dDocumentCommandProcessor for the individual machines.


>From a2d point of view, how many document template and view templates would

Should I try to squeeze all machine types in one doc template and some views? 
Then I would have to allow only the applicable view.

Or two file extensions (doc templates), one for graphics, one for dialogs? 
Should I intercept the dialog types and handle them entirely myself? 

Is it possible(reasonable) to have a view without canvas, just a common wxPanel 
with the usual controls?

What's your ideas or recommendations?

Thank you very much! Michael
