Private vs. Public methods
Public versus Private methods
In the DHTML Suite, all private methods starts with two underscores("__"). They are helper methods used inside the DHTML Suite.
It's important that you don't refer to any of these methods in your code. Private method may change over time and this may cause your code to break in case you use them. If you can't find the public method you need, please request one at the forum.
Properties
In the DHTML Suite, all properties are considered to be private. If you need to access a method, use a getMethod.
