(updated)UIScrollBar and my own class. Can they works together?

Question

Hi Eone,
i'm implementing a uiscrollbar in a class of mine that extends textfield. Unluckly it gives to me  a lot of 1120 error, undefined property, in each row i use a property of this component (except the constructor).
I read somewhere that As2 not allow to use uisbar in other type of class that extends movieclip or textfiled or you know what...
It's the same in As3?
EDIT:
I found a solution. Some method an properties of UISB can be used in the cvlass (like, contructor, update, target). Some otherelse not. So the other can be used only when i do an instance of my own class, like properties of the instance. Ex:
textfield.UISB.x = 100;
textfield: instance of my class
UISB: scrollbar declared within my class
x= properties defined only instancing my class

You need to read the basics about Swing events.
For starters, you do not implement listeners in your Applet class. Instead, you add new listeners to specific components that you want to listen on. For example, if you need to perform certain actions when a JComboBox's selection changes, you would do something like:
my_combo.addActionListener(  new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        System.out.println("selection changed to: " + my_combo.getSelectedItem());
});And for buttons:
my_button.addActionListener( new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        System.out.println("You clicked " + ((JButton) e.getSource()).getText() " button);
}MoustListener and other listeners can be similarily added. See JDK Documentation or Tutorials
