Events on document class

[Walker_Boh]

Hi all!

I have a problem...if I attach an event (mouse_move) on a document class (that extends movieclips) it traces the coordinates of the mouse pointer only when I pass over his children. Why it doesn't trace also in the empty area? I need to catch the coordinates of the mouse everywhere ...

Thanks in advance

Try adding the eventlistener to the stage like this:

this.stage.addEventListener(MouseEvent.MOUSE_MOVE, showCoords);

Hi Joergen, in this way it works, but I don't understand why it doesn't in the other case... The document class extends movieclip so using mouse_move directly on it should work ...

Thanks for the help

Sorry to jump in here... You have to tell your code what display object is creating the event. If, by setting your listener to the stage object as Joergen suggested, then you have access to the full width and height of your movie, whereas with just setting your listener to a movie clip on the stage, you only have access to the dimensions of that clip.

Hi xchanin,

But doesn't the document class have the same width / height of the stage? It is a movieclip too but if I put a listener here it reports only the coordinates when I pass over a child...

Thanks!

Oh I see what you're saying: by either leaving the target for the event listener empty
addEventListener(MouseEvent.MOUSE_MOVE,test);

or by populating it with' this'
this.addEventListener(MouseEvent.MOUSE_MOVE,test);

then the mouseover is only working on the actual movie clip added to the stage. I'm not exactly sure why it defaults this way, maybe someone else in here has the answer to your question.

Well, I see it this way:
When the player starts, it generates a displaylist with the stage at the root and an instance of the document class on top of that. Then it adds all other objects placed on the stage at design time.
The instance of the document class has no graphical extension, so adding the listener to that instance will only generate listening behavior from it's graphical descendants.
On the opposite, adding the listener to the stage will generate listening behavior from the stage and all descendants.
I wonder, if this is the correct interpretation?

Hi !

I think you are right...the strange thing is that the document class is a movieclip...so it should accept listener too...

Thanks
