Object Naming UnConventions

[dunbarx at aol.com]

I rarely get to act like a pedantic jerk, especially towards a highly respected and iconic personage such as Richard Gaskin.


Not kidding about any of item 2 of line 1.


But ordinal would be 'first control". Cardinal would be "control 1"


That felt better than I thought it would.


I am sure I will regret it, though.


No kidding about item 1 of line 5.

Good stuff, Mark.

Oddly enough, for all the tediously curmudgeonry in my naming 
conventions article, it doesn't deal much with object names, only 
variables, handlers, etc.

In code, object names usually appear after a type specifier, e.g.:

   click at the loc of btn "btnSend"

...so it never occurred to me to prefix the object name itself.

This prompted me to try something I'd never used before, addressing a 
control using only the "control" specifier followed by the name:

   put the rect of control "btnSend"

Sure enough, it works.

I don't know why this surprises me, since I've been using ordinal 
reference with "control" for years, e.g.:

    repeat with i = 1 to the number of controls
       get the rect of control i
       ...


Somehow I'd gotten the idea that the "control" specifier was limited to 
ordinal references, but apparently it's not.

So thanks for your post.  It prompted me to learn something new, and if 
I get time I may add a section to that article on object names.
