Flash UI component not being 'repainted' when user uses browser zoom (only on Mac/Safari)

Hi,

I have flash component in a website, which shows a preview. There are some UI components overlaid on the preview to allow navigation. Unfortunately it seems that in Safari on Macs, there is a problem:

When the user zooms in or out (using the browser based page zoom), my overlaid UI items disappear for some reason. This does not happen on any other platform.

I would have though that this zoom function would be something that is taken care of solely by the browser/Flash plugin, however, perhaps there is something I can do to force a 'redraw'?

Has anyone else come across this problem?

Thank you

+1 A:

It is very hard to replicate your scenario because of non specific descriptions.

What version of Flash are you using ?
Which components are you using(what are 'some UI components' ?
What is a 'preview' ? Is just an image, it is a complex item renderer ? If it's an image, how large is it ?
What do you mean by 'browser based zoom' ? Is it Flash Player's context menu Zoom In option ? Is it CMD+ ?

Without proper details I would advise you try invalidate(), validateNow() or drawNow()...maybe, just maybe.

1. Built using Adobe Flash CS4 (the player causing problems is the latest version I believe).2. The UI 'components' are just standard flash movieclip buttons. 3. Yes just and image (could be approx 200k), but I don't think this is relevant, the image is displaying fine. 4. Yes, the zoom functionality provided by the browser, not the flash player (ctrl + on firefox).Regarding the functions you mention, when am I suppsed to call these? As far as I know there is no 'onZoomed' event that I can hook into.

@UpTheCreek I'll have access to Flash CS4 tomorrow, so no solution yet. Thanks for clearing things out a bit. 2.) So you have some fl.controls.Button instances on top of an image(Loader, or something) and when you zoom in using the context menu(Zoom In), the buttons disappear , right ? 3.) I meant image dimensions(width,height). File is irelevant. Dimensions wise BitmapData instances are limited to 8192 pixels in width/height. I've got an idea for a 'handmade' onZoomed event

Thanks for your help. The image is well within those dimension limits.

@UpTheCreek I've placed a ScrollPane with a large image and placed a Button(fl.controls) on top and had no problem zooming in. I can't seem to replicate your issue. Can you add steps for me to reproduce your scenario and spot the problem ? Also, for the 'onZoomed', have a look at this answer: http://stackoverflow.com/questions/1374179/actionscript-3-contextmenu-closed-event/1376316#1376316
