var _alpha // The alpha transparency value of the button specified by my_btn. Valid values are 0 (fully transparent) to 100 (fully opaque). The default value is 100. Objects in a button with _alpha set to 0 are active, even though they are invisible.
var enabled // A Boolean value that specifies whether a button is enabled. The default value is true.
var _focusrec // A Boolean value that specifies whether a button has a yellow rectangle around it when it has keyboard focus.
var _height // The height of the button in pixels.
var _highquality // Specifies the level of anti-aliasing applied to the current SWF file.
var _name // Instance name of the button specified.
var _parent // A reference to the movie clip or object that contains the current movie clip or object. The current object is the one containing the ActionScript code that references _parent.
var _quality // Sets or retrieves the rendering quality used for a SWF file. Device fonts are always aliased and therefore are unaffected by the _quality property.
var _rotation // The rotation of the button, in degrees, from its original orientation.
var _soundbuftime // An integer that specifies the number of seconds a sound prebuffers before it starts to stream.
var _target // Returns the target path of the button instance specified.
var _url // Retrieves the URL of the SWF file that created the button.
var _visible // A Boolean value that indicates whether the button specified by my_btn is visible.
var _width // The width of the button, in pixels.
var _x // An integer that sets the x coordinate of a button relative to the local coordinates of the parent movie clip.
var _y // The y coordinate of the button relative to the local coordinates of the parent movie clip.
var _xmouse // Returns the x coordinate of the mouse position relative to the button.
var _ymouse // Indicates the y coordinate of the mouse position relative to the button.
var _xscale // The horizontal scale of the button as applied from the registration point of the button, expressed as a percentage. The default registration point is (0,0).
var _yscale // The vertical scale of the button as applied from the registration point of the button, expressed as a percentage. The default registration point is (0,0).
var menu // Associates the ContextMenu object contextMenu with the button object my_button. The ContextMenu class lets you modify the context menu that appears when the user right-clicks (Windows) or Control-clicks (Macintosh) in Flash Player.
function getDepth() // Returns the depth of a button instance.
function onDragout() // Invoked when the mouse button is pressed over the button and the pointer then rolls outside the button.
function onDragover() // Invoked when the user presses and drags the mouse button outside and then over the button.
function onKeyDown() // Invoked when a button has keyboard focus and a key is pressed. The onKeyDown event handler is invoked with no parameters.
function onKeyUp() // Invoked when a button has input focus and a key is released. The onKeyUp event handler is invoked with no parameters.
function onKillFocus() // Invoked when a button loses keyboard focus. The onKillFocus method receives one parameter, newFocus, which is an object representing the new object receiving the focus. If no object receives the focus, newFocus contains the value null.
function onPress() // Invoked when a button is pressed. You must define a function that executes when the event handler is invoked.
function onRelease() // Invoked when a button is released. You must define a function that executes when the event handler is invoked.
function onReleaseOutside() // Invoked when the mouse is released while the pointer is outside the button after the button is pressed while the pointer is inside the button.
function onRollOut() // Invoked when the pointer moves outside a button area. You must define a function that executes when the event handler is invoked.
function onRollOver() // Invoked when the pointer moves over a button area. You must define a function that executes when the event handler is invoked.
function onSetFocus() // Invoked when a button receives keyboard focus. The oldFocus parameter is the object that loses the focus. For example, if the user presses the Tab key to move the input focus from a text field to a button, oldFocus contains the text field instance.
