Mouseover and Mouseout

[Mads Jon Nielsen]

Hey..

I think i have found an odd behavior.
Either that or i don't quite understand how lime handle Mouseover and
Mouseout events.

----
Here is a app created in pure JS where i'm testing how onmouseover and
onmouseout is working.
The behavior of this example was how i expected lime to work as well,
but that is not the case.
Pure JS (https://docs.google.com/viewer?

----

----
I have added a sprite to a scene in this example and listening on
mouseover and mouseouts on the scene and the sprite.

Heres my issue:
I'm not receiving mouseout on SCENE, when i hover the SPRITE, instead
i'm getting a mouseout on the sprite.
When i'm exiting the SPRITE, i'm receiving a mouseover and mouseout on
the SPRITE. Expected behavior should be mouseout on Sprite mouseover
on Scene.
LimeJS Example (https://docs.google.com/leaf?

Is this a bug, or is it just me that don't understand the behavior of
mouseover and mouseout in Lime?

Hi

Yes, mouseover and mouseout are tricky because LimeJS does not rely on
events on actual Dom nodes. All core events are actually dispatched
from single parent node. This lets use use canvas based render trees
and provide touch support on the same level as mouse
interaction(obviously no mousover/mousout there though).

Simple solution is to listen events on dom nodes(if you know you will
always have them). Other way is to keep a value if shape is currently
hovered or not in Javascript. I wrote a gist that should do that:
https://gist.github.com/1153666 . I didn't include it in the source
cause it isn't really in same style as rest of the API. If you have
suggestions how to make it better (or if it still does not give right
results) let me know.

Yups, listening on the dom element did the trick.

I'll let you know if i come up with any nifty way to do this...

This worked for me:

goog.events.listen(square, 'mouseover', function(e) { 

this.setFill(128,0,0); //highlight

var key = goog.events.listen(this.getParent(), 'mousemove', function(e) {

if (!this.hitTest(e))

{

this.setFill(128,128,128); // unhighlight

goog.events.unlistenByKey(key);

}

},null,this);

});

cheers,

John

this code is giving error which i mentioned in upper line.
