addListeners, event handler and all

May someone tell me how is it possible (if it is) to pass variables along when we addEventListeners to a component button.
And by the way, what’s the main differences between addEventListeners and addListener?

I have a FLVPlayback component from which i wanna play 4 different flv clips referenced in a xml file.

The xml part works fine.

So I have my 4 buttons (components) here. When i click the button 1, i want to either send the variable 1 to a function that is build to load the desired flv in the player. The variable would determine which of the flv to play.

either that or when i click a button, i want to set directly the .contentPath of my flv player, load it and play it via a simple function that would be referenced to in the addEventListener call

I hope everything is clear enough.

I’m having trouble just making the buttons send different variables to a particular function, according to which of my 4 buttons are pressed.
button 1 sends 0
button 2 sends 1
button 3 sends 2
button 4 sends 3

that looks pretty simple but seems like i cant even do that by myself.

Thanks for the help again
