Workaround is also provided for Internet Explorer 6's growing textarea bug.

Class Field Summary
Internal	`_supportedPartialProperties` Array containing properties that may be updated without full re-render.

Instance Method Summary
Public, Virtual	`sanitizeInput()` Invoked to ensure that input meets requirements of text field.
Internal	`_renderStyle()` Renders style information: colors, borders, font, insets, etc.
Internal	`_addEventHandlers()` Registers event handlers on the text component.
Internal	`_adjustPercentWidth()` Reduces a percentage width by a number of pixels based on the container size.
Internal	`_processBlur()` Processes a focus blur event.

Methods inherited from class Echo.Render.ComponentSync

renderAdd, renderDispose, renderUpdate

sanitizeInput

Invoked to ensure that input meets requirements of text field. Default implementation ensures input does not exceed maximum length.

_renderStyle

Renders style information: colors, borders, font, insets, etc. Sets percentWidth flag.

_addEventHandlers

Registers event handlers on the text component.

_adjustPercentWidth

Reduces a percentage width by a number of pixels based on the container size.

Parameters:: percentValue (Number) - the percent span; reducePixels (Number) - the number of pixels by which the percent span should be reduced; containerPixels (Number) - the size of the container element

_processBlur

Processes a focus blur event.

_processClick

Processes a mouse click event. Notifies application of focus.

_processFocus

Processes a focus event. Notifies application of focus.

_processKeyPress

Processes a key press event. Prevents input when client is not ready.

_processKeyUp

Processes a key up event.

_processRestrictionsClear

Event listener to process input after client input restrictions have been cleared.

renderAddToParent

Adds the input element to its parent in the DOM. Wraps the element in a special container DIV if necessary to appease Internet Explorer's various text field/area bugs, including percent-based text areas inducing scroll bars and the IE6 percentage width "growing" text area bug.

Parameters:: parentElement - the parent element

renderDisplay

renderDispose

renderFocus

renderUpdate

_storeValue

Stores the current value of the input field, if the client will allow it. If the client will not allow it, but the component itself is active, registers a restriction listener to be notified when the client is clear of input restrictions to store the value later.

Parameters:: keyEvent - the user keyboard event which triggered the value storage request (optional)
