[Dynapi-Dev] Re: scrollheight and ie 5 on the mac

[Rob R. <ro...@ma...>]

Okay I'm building a menuing system using DynAPI, everything is working great
on window ie v5 and netscape v4, and mac netscape v4 but in testing the
thing out on mac ie 5 I've run into an annoying problem.

The menu is being built on the fly, I'm never sure how many lines of text
will be in a menu entry because of the length of some item we wrap the text.
Also the system is such that images can be substituted in for HTML text and
it will work just fine, again image size from entry to entry may vary. So
I've built the system such that each menu item is its own layer and as the
content is added to the layer the height of the layer is determined using
"getContentHeight()" and this value is tracked by the menu manager so it can
work out where to position then next menu item.

The problem I've come across is this on the Mac IE 5 getContentHeight
returns as "NaN" a little exploration and it turns out that
"this.elm.scrollHeight" which the getContentHeight() call uses returns
"undefined". Other properties of the "elm", such a visibility return just
fine. When I create a layer the standard way right in the HTML and query the
scrollHeight Mac IE 5 returns the correct value. It may be a matter of
timing as when I query the scrollHeight, but I do have the layer existing
via the addChild call and as I said it works on all the other browser
platform setups so I'm stumped. Any ideas?

Thanks,
