Instances or subclasses which use a different Template to create a different DOM structure may need to provide their * own implementation of this method.

The default implementation which provides data for the default {@link #template} returns an Array containing the * following items:

The Button's {@link #text}
The <button>'s {@link #type}
The {@link iconCls} applied to the <button> {@link #btnEl element}
The {@link #cls} applied to the Button's main {@link #getEl Element}
A CSS class name controlling the Button's {@link #scale} and {@link #iconAlign icon alignment}
A CSS class name which applies an arrow to the Button if configured with a {@link #menu}
A CSS class name applied to the Button's main <tbody> element which determines the button's scale and icon alignment.
A CSS class to determine the presence and position of an arrow icon. ('x-btn-arrow' or 'x-btn-arrow-bottom' or '')
The {@link #cls} CSS class name applied to the button's wrapping <table> element.
The Component id which is applied to the button's wrapping <table> element.
