[Dynapi-Dev] A simple question

[francesco A. <fa...@we...>]

Hi,

when i call deleteElement in Netscape 4 the layer is really deleted or is
only hide?

I have see that the layer is only set to hide.

Can the Dom of netscape 4 really cancel an elemement from the memory?

no.  the layer is only hidden.  It is also placed in an array that is used
when another DynLayer is created.  This way, new layers are only created when
needed.

Hi,

I have glanced through the Dynapi code and realized that deleted layers are
seldom recycled.  I guess this is because when creating a new Layer in Netscape
4x, an initial width has to be specified to ensure proper wrapping of text.
Thus, a deleted layer can only be recycled if the new layer to be created intend
to have  the same initial width.  Please correct me if I am wrong.

Layers will always be recycled on NS4, no dependency on the size or
anything.
the Layer object is still in memory, and can be simply resized seeing that
it's contents will be rewritten anyway. The layer's size is reset before the
HTML is written into it..

so glance at it again :-) (and focus on the createElement() method)

Re: [Dynapi-Dev] A simple question

The only way to delete a layer in NS is rewrite the HTML of its parents.
Something that can't be done in many cases. We could add this to
deleteAllChildren().
