Subject Design View AIR App (Was: Re: Apache Flex GUI Designer tools)
Date Tue, 02 Oct 2012 19:56:46 GMT
I am very interested in building the design view as an AIR app.  Lets talk
design/architecture now.

Here is a brain-dead architecture design of the AIR app, that lets the user
interactively drag and drop components, apply layouts, change labels/titles

Conceptually, this is simple enough.  This contains the following

1.  Components list: We read the list of available components from a
manifest file and populate a toolbox on the side.
2.  Design area:  This would be a container where we will draw the objects
3.  Interactive layer:  Any object or group of objects in the design area
can be selected, resized, rotated, constrained.
4.  Properties area:  Properties such as: styles, skins, layout of selected
components could be changed here.
5.  Skins could be created/edited in the same way.  They could also be
applied onto their corresponding Host Components as well.
6.  Generate MXML:  This is the part that I am unclear.  My first thought
is to walk through the flash player display hierarchy and create an XML
containing all the components in the screen along with their properties and
styles.  Feed this primitive XML into Falcon (lots of hand-waving here)
which spits out MXML.  This MXML can be edited in the IDE.

Bonus features:
1.  Hooking up to Data services
2.  Round-tripping between Design View <=> IDE
3.  Writing Eclipse/IDEA plugins as wrappers around this AIR app so that it
can be integrated into IDEs.

I *know* I am missing something obvious above.  Please provide your
feedback so that we can iteratively fill out the design.
