hi all,

i know this is not a PureMVC centric question, but as most guys here seem to use flex i ask it anyways.
I have this viewstack:

:
<mx:ViewStack id="vwStack" left="0" top="0" right="0" bottom="0" resizeToContent="true" creationPolicy="auto">
<view:ImageViewer id="imageViewer"/>
<view:Player id="player"/>
<view:AssetPreview id="preview" bottom="80" width="100%"/>
</mx:ViewStack>
I want the child "preview" (a small one) to be visible in front of current active child f.e. on a mouseOver. At the moment it only shows one child at a time and the others are not visible. How can i do that?

The viewstack will ALWAYS show only one child. Something along these lines is what you'll probably want:

               
:
<mx:ViewStack id="vwStack" onMouseOver="showPreview=true" onMouseOut="showPreview=false">
<view:ImageViewer id="imageViewer"/>
<view:Player id="player" />
</mx:ViewStack>
<view:AssetPreview id="preview" bottom="80" width="100%" visible="{showPreview}"/>

thanks cliff, but this will show the AssetPreview-Component below the active viewstack component, won't it? I want to show the preview in front of the active viewstack component. I figured out that maybe i can manage that with PopUpManager, but i'm not sure if this works nice with mouseOver/mouseOut.

regards, Thomas

The order posted above should be displayed overtop the viewstack if they're both children of a canvas. Successive MXML declarations are rendered above each other.

And yes, you could do it as a popup if you wanted to, but that'd be more effort.

hi again,

this doesn't work. i have the following code and the AssetPreview component is shown below the active view stack componenent  :-\

:
<mx:Canvas>
<mx:VBox x="0" y="0" height="520" width="600">

<mx:Button id="videomode" label="video"/>
<mx:Button id="imagemode" label="image"/>
<mx:ViewStack id="vwStack" left="0" top="0" right="0" bottom="0" resizeToContent="true" creationPolicy="auto">
<view:ImageViewer id="imageViewer"/>
<view:Player id="player"/>
</mx:ViewStack>
<view:AssetPreview id="preview" y="150" width="100%" visible="true"/>
</mx:VBox>
</mx:Canvas>

Am i missing something?

p.s. the viewstack also doesnt have mouseOver/mousOut event handler, but this is not my big problem.

regards, Thomas

ok, got it. Its because the Assetpreview component is in the vbox. Outside of this, it works!

Your container holding the viewstack and the preview is a VBox. That control lays its children out vertically.
