Summary:
_FormWidget's correspond to native HTML elements such as <checkbox> or <button>.
Each _FormWidget represents a single HTML element.
All these widgets should have these attributes just like native HTML input elements.
You can set them during widget construction.
They also share some common methods.

// Update the visual state of the widget by setting the css classes on this.domNode

//
// In the case where a widget has multiple
// states, it sets the class based on all possible
// combinations. For example, an invalid form widget that is being hovered
// will be "dijitInput dijitInputInvalid dijitInputHover dijitInputInvalidHover".
//
// For complex widgets with multiple regions, there can be various hover/active states,
// such as "Hover" or "CloseButtonHover" (for tab buttons).
// This is controlled by a stateModifier="CloseButton" attribute on the close button node.
//
// The widget may have one or more of the following states, determined
// by this.state, this.checked, this.valid, and this.selected:
// Error - ValidationTextBox sets this.state to "Error" if the current input value is invalid
// Checked - ex: a checkmark or a ToggleButton in a checked state, will have this.checked==true
// Selected - ex: currently selected tab will have this.selected==true
//
// In addition, it may have one or more of the following states,
// based on this.disabled and flags set in _onMouse (this._active, this._hovering, this._focused):
// Disabled - if the widget is disabled
// Active - if the mouse (or space/enter key?) is being pressed down
// Focused - if the widget has focus
