[Dynapi-Dev] The 7th argument in DynLayer - Introducing the StyleManager

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

Hello Everyone,

I've been doing some thinking and came up with a
solution that I think is able to give us more speedy
layers than what we currently have. 

The solution employs a StyleManager that will enable
us to be able to change the look, feel and behavior of
DynLayers and widgets. 

With this in mind I would like to make a proposal that
we change the 7th argument in DynLayer to use the
"style" argument instead of image.

IMO background image in rarely used by developers and
could be easily changed with the use of setBgImage or
dictionary object ({}) in those rare cases. I think
the "style" argument will be used much more frequently
than bgimage.

Possible usage of styles:

// create a plain DynLayer
var l = new
DynLayer(null,0,0,10,10,null,'PlainLayer');

// creates an html container 
var l = new
DynLayer('Hello',0,0,null,null,null,'HTMLLayer');

var l = new DynLayer(null,0,0,0,0,null,'CoverLayer');

The above layers will use customize code found in the
Style object to improve the creation speed of the
layers.

What do you think? If it's a no, then I guess we'll
just have to use setStyle() and keep the image
argument.

Hello,

As I have used bgImage as the 7th param'. I would
prefer not to change. Don't we have a setClass('style')
or are you using the new parameter as a hard coded
string to integrate with HTMLcomponents? Which
seems to have css as the first param' and is set to null? 

With an established interface it is preferable to add to,
rather than change and break backward compatibility

The StyleManager is not about CSS. It's about being
able to apply javascript functions to an exiting
widget to modify it's functions, change it's look and
it's behavior.

For example you can use the StyleManager to convert an
ordinary DynLayer into a button widget by just
applying the "ButtonStyle". Later you could then
change that layer into a ProgressBar by just applying
the "ProgressBarStyle".

IMO it's a completely modular and fashionable way to
design DynAPI widgets. With StyleManager a basic
widget can be morphed into another widget by just
simply changing the style.

Ok, I guess we'll just keep the 7th argument and use
setStyle() to change styles on DynLayers.

My thinking is:

button1=new Button()
button1.setHighLight(...)
progressbar1=new ProgressBar()
progressbar1.setScale(...)
...
Morph button1 to a progressbar
...
button1.setScale(..) ?

How would we know button1 has new methods as
setScale() was before meaningless for a button?

button1 and progessbar1 are instances of their own class
with separate attributes and methods. Morphing button1
to a progressbar? Ok fine, but morphing 'setStyle(...) or
maybe setMorph(...)' is not a method of either class but
more a method of a management class not related to (or
inherited from) a DynLayer.

Perhaps an example would help in understanding what is
intended in an OOP context. Thanks.

Hi,

Once I'm done with a simple example I'll post it to
the list.
