[Laszlo-dev] implementing non-rectangular masks in LZX

[Sarah Allen]

I did a little looking into how this is done in Flash (swf7, scriptable 
masks).  If you are intested, there's a nice tutorial here: 
http://www.kirupa.com/developer/actionscript/scriptable_masks.htm .  The 
cliff notes are:
    myMovieClip.setMask(maskMovieClip)

After playing with it a bit, I think I want a mask to be another view, 
so I can resize and position it.  Ideally something like:
    <view resource="myimage_rsc" mask="anotherview"/>

I created a little test with the ActionScript inlined just to get the 
hang of things.  This works fine:

    <view id="myview" resource="photo.jpg">
        <method name="setMask" args="v">
            Debug.write('setMask', v, v.__LZmovieClipRef);
             this.__LZmovieClipRef.setMask(v.__LZmovieClipRef)
        </method>
    </view>
    <view id="mymask" oninit="myview.setMask(this)" resource="star.swf"
        x="130" y="-20" width="200" height="200" stretches="both"/>


However, when I make the mask clickable (simply setting clickable="true" 
will do it), the mask disappears when my mouse goes out of the mask's 
bounds and reappears when the mouse goes back in.  I didn't see anything 
magic in LzView's setClickable. 

Can anyone else give me a clue as to why this would happen?

Thanks,
Sarah

p.s. I've been testing in lps-3.3.  As soon as I sync trunk, I'll check 
into a test directory if anyone else wants to see it in action.
