Re: [Adobe-source-devel] ASL and nibs

[Sean P. <sp...@ad...>]

Not quite sure what you mean by an "ASL dialog"? Do you want to  
connect a nib based layout to an Adam sheet? Do you want to connect  
it to an Eve layout? I'd guess you are going to try to connect it to  
an Adam sheet to pick up the logic.

All of the components of ASL can be used individually - you can use  
adam_parser/evaluate/adam to construct your sheet, then read in your  
nib (I assume you just want to let the Mac just construct your  
dialog) - then traverse the HIView and bind the carbon events you  
want to cells in the sheet (if you have a string for a property and  
you want to parser it you can use the expression parser and  
virtual_machine to parse and evaluate it). To see how to bind to  
carbon events, take a look at the Mac UI core implementation. I  
wouldn't object to having a Mac only addition that let you construct  
our widgets (like a checkbox_t) from an appropriate HIView.

If you want to use an Eve layout, things get a bit more tricky as you  
need to provide Eve with the layout hierarchy - you could do that  
from a carefully constructed nib (maybe using some panels as proxies  
for row/column layout) - but inferring a layout isn't going to work.

Going with nibs you'll lose the dynamic layout that Eve enables,  
localization, and cross platform descriptions - I'm hoping someone  
will step up to write a visual editor (the infamous Expresso double- 
shot) then we can have the best of both worlds. The ASL components  
are all being designed with a visual editor in mind (this is why  
comments are built into the syntax for Adam and Eve - to support  
round-trip editing). We'll get there eventually.
