Extending classes

[dorraba]

Hi.

How do I Create a class that extends from the ComboBox Class and Associate it with a ComboBox that I have placed in a fla Document?

You can't, because V2 components cannot be changed or additional features be added. You need to create your own component.

but I saw some tutorials that wrote:

class aaa extends MovieClip{}

Of course you can extend the functionality of any movieclip using extends but not V2 components, since they are as I said above compiled clips and you cannot add functionality to them. You can only make your own combobox.

O.K.
So you meen I can add functionality to a combobox in a new class that inherits from the combobox but in that class I can't change functions of the combobox?

No, you cannot add more functionality to the combobox component provided by MM (or Adobe MM ). You need to make your own component from scratch.
Put a combox instance on stage. Then open the library and click on combobox symbol and then on the top right corner of the window and select Properties from the menu. That will give you the answer. repeat that with any of your own movieclips.
