Michael, I'd have no objections to a DynLayer.setTextSelectable() method - just not
setSelectable() cause I'm using it widgets sometimes. For stopping the right mouse
"context menu", we could create a new event on DynDocument - "oncontextmenu" and
disable the default action whenever that event is listened for.
I was not able to get synchronous loading working in IE 5, even with the "defer" value
set to true or false. And it's not going to work in NS4 also. When using
createElement('script'), the first time you load a script and immediately call a
function contained in it, it fails. The second time you load it it works. I had to
wait for the "onreadystatechange" event to call in order to get around it.
As far as I see there's going to be no other option but going with asynchronous
loading. The way I handled it is to create a proper dependency list before trying to
load an object. It would be nicer to let each object define it's own requirements but
without synchronous loading it just isn't possible without a VERY "confusing web of
intermediate methods" :). So I'm going with the easy cop-out solution.
When you "add()" an object to the library tree it simply ensures that any objects that
are required by the script are loaded before it:
DynAPI.library.add('DependentObj','dep.src');
DynAPI.library.add('Obj','obj.js','DependentObj');
DynAPI.library.load('Obj'); // loads DependentObj before Obj
For the dynapi core files, we'll include a ready made dependency list:
DynAPI.library.add(['DynEvent','EventObject','DynElement'],DynAPI.libraryPath+'dynapi/api/event.js');
DynAPI.library.add(['DynDocument'],DynAPI.libraryPath+'dynapi/api/dyndocument.js',['DynEvent']);
DynAPI.library.add(['DynLayer'],DynAPI.libraryPath+'dynapi/api/dynlayer.js',['DynDocument']);
DynAPI.library.add(['MouseEvent'],DynAPI.libraryPath+'dynapi/api/mouse.js',['DynLayer']);
So in a page you'd just do this to load everything up:
DynAPI.library.load('MouseEvent', function() {
alert(MouseEvent+' '+DynLayer);
});
I'll also add object grouping so that you can also do:
DynAPI.library.load('DynAPI.api');
And also with that, we can attach the constructors to the DynAPI.api object:
DynAPI.api.DynLayer = DynLayer;
This will be useful in cases where you're working with frames and windows that are
opened from a frame containing DynAPI. You could just open up a window and call the
following inside it:
var DynAPI = window.opener.DynAPI;
var doc = new DynAPI.api.Document(this);
var lyr = doc.addChild(new DynAPI.api.DynLayer());
Or even better it would be easy to rescope the objects to that frame, maybe something
like this:
var DynAPI = window.opener.DynAPI;
DynAPI.library.scope('DynAPI.api.*', this);
alert(DynLayer);
There's lots and lots of fun to be had with this library loader as long as you can get
used to the dependency list requirement.
(brainstroming...) There actually there probably will be a way to get files to load
their required scripts without using a dependency list. I by default call the
function called "main()" if it's available in the script, it is called when the script
is finished loading. Inside that script you could then call
DynAPI.library.load('DependentObj', construct), and in the construct() object create
your object.
