[Dynapi-Dev] New BlackBoard concept for DynAPI 3.0

[Raymond I. <xw...@ya...>]

Hello everyone,

Sometime ago some of our users had a problem with
setHTML(). Whenever setHTML() was called after you
added a child layer it would erase the child and
overwrite the html content.

The BlackBoard approach:

lyr.setBlackBoard(b,x,y);

Once the blackBoard is setup (before the layer is
created) you can then call setHTML() and if will not
erase the child layers but overwrite the html content.
This will make it easier for us to create things like
the button widget:

lyr.setBlackBoard(true);
lyr.addChild(new DynLayer(),'_lyrCover');
dynapi.document.addChild(lyr);
lyr.setHTML('Click Here');
lyr._lyrCover.setAnchor({left:0,top:0,stretchH:'100%',stretchV:'100%'});
....
lyr.setHTML('Ok');

Any comments?

I like very much.
Should it be an extension?
I think it would be best as a native functionality (imho)
Basically, are we looking at a seconf layer to hold HTML (or children?)?
Or would we simply cause the re-rendering of child layers from the children
array?

Note: that if we are talking re-rendering the layers you will run *SMACK*
into the netscape 4.x
memory leak.

I'm also of the opinion that it should be a native
function.

Yes. A layer (not a DynLayer) will be used to store
the HTML content. In DOM browsers I was looking at
using a <table> object, but I think I might use a
<div>. And for NS4 I'll use a <layer>

I'm also looking at adding a two new features to the
dynapi.document object. These are as follows:

dynapi.document.writeln(html,key) and
dynapi.document.deleteln(key)

These will allow a user to write/append html content
to the document even after the page has been loaded.
The deleteln(key) will also the user to delete html
content from the document once the page is loaded. 

These two new functions will enable us to dynamically
download (inline) portions of a huge app, append the
content to the document and then create the object use
blueprint/inline create features.

What do you all thing?

I thing it's a greate idea!!
This would have come in very handy when I built figure8's site as
I would have allowed be to load only portions of the tree at a time.
(800+ nodes can take a VERY long time to download, never mind rendering)

Well these two functions will require a lot of
testing, but I think it's possible after many
sleepless nights :)

Raymond:
Let us know when you have the blackboard code and example in cvs..
I will need it to create the DynButton, otherwise I need to add two layers
(plus itself = 3 layers)
to make the 3d effect work.
Once the button is done, I will re-implement the scrollbar and we will be
back on track.

So note to Raymond: making blackboard a priority would be prety cool..
hehe..
:-)

Still hammering out the specs for the new tree widget or, DynTree..
I'll post the specs as soon as I've got them.
