- ## Method Summary

  Modifier and Type
  Method
  Description
  `static void`
  `changeAutoChildDefaults(String autoChildName, Canvas defaults)`
  Changes the defaults for Canvas AutoChildren named `autoChildName`.
  `static void`
  `changeAutoChildDefaults(String autoChildName, FormItem defaults)`
  Changes the defaults for FormItem AutoChildren named `autoChildName`.
  `static void`
  `changePickerIconDefaults(FormItemIcon defaults)`
  `void`
  `deselectValue()`
  If this item currently has focus, clear the current selection.
  `void`
  `deselectValue(Boolean start)`
  If this item currently has focus, clear the current selection.
  `Boolean`
  `getBrowserAutoCapitalize()`
  `Boolean`
  `getBrowserAutoCorrect()`
  In Mobile Safari, should automatic correction be offered for text in the item's text box? If `null`, then Mobile Safari determines automatically whether to enable autocorrect.
  `Boolean`
  `getChangeOnKeypress()`
  Should this form item fire its `change` handler (and store its value in the form) on every keypress? Set to `false` to suppress the 'change' handler firing (and the value stored) on every keypress.
  `String`
  `getEditProxyConstructor()`
  Default class used to construct the `EditProxy` for this component when the component is `first placed into edit mode`.
  `boolean`
  `getEnforceLength()`
  If a `length` is specified for this item, should user input be limited to the specified length? If set to true, user input and values passed to `setValue()` will be trimmed to the specified length.
  `String`
  `getEnteredValue()`
  Returns the raw text value that currently appears in the text field, which can differ from `FormItem.getValue()` in various cases - for example: for items that constrain the value range, such as a `DateItem` with `enforceDate`:true, or a `ComboBoxItem` with `addUnknownValues`:false for items with a defined valueMap or edit value formatter and parser functions which converts display value to data value while the item has focus if `changeOnKeypress` is false
  `Boolean`
  `getEscapeHTML()`
  By default HTML characters will be escaped when `canEdit` is false and `readOnlyDisplay` is "static", so that the raw value of the field (for example `"<b>AAA</b>"`) is displayed to the user rather than the interpreted HTML (for example `"AAA"`).
  `Boolean`
  `getFormatOnBlur()`
  With `formatOnBlur` enabled, this textAreaItem will format its value according to the rules described in `FormItem.mapValueToDisplay()` as long as the item does not have focus.

  `Boolean`
  `getPrintFullText()`
  When generating a print-view of the component containing this TextArea, should the form item expand to accommodate its value? If set to false the text box not expand to fit its content in the print view, instead showing exactly as it does in the live form, possibly with scrollbars.
  `int[]`
  `getSelectionRange()`
  For text-based items, this method returns the indices of the start/end of the current selection if the item currently has the focus.

  - ### setEnforceLength

    public TextAreaItem setEnforceLength(boolean enforceLength)
    If a `length` is specified for this item, should user input be limited to the specified length? If set to true, user input and values passed to `setValue()` will be trimmed to the specified length. Otherwise values exceeding the specified length will raise an error on validation.

    Note that having this value set to true limits user interactivity in some ways. For example users would be unable to paste a longer string into the field for editing without seeing it be truncated. Given how text areas are typically used to edit longer values than non-wrapping `TextItem`s, this value is false by default for textAreaItems.

    Parameters:
      `enforceLength` - New enforceLength value. Default value is false
    Returns:
      `TextAreaItem` instance, for chaining setter calls

  - ### getEnforceLength

    Note that having this value set to true limits user interactivity in some ways. For example users would be unable to paste a longer string into the field for editing without seeing it be truncated. Given how text areas are typically used to edit longer values than non-wrapping `TextItem`s, this value is false by default for textAreaItems.

    Returns:
      Current enforceLength value. Default value is false

  - ### setEscapeHTML

    public TextAreaItem setEscapeHTML(Boolean escapeHTML)
    By default HTML characters will be escaped when `canEdit` is false and `readOnlyDisplay` is "static", so that the raw value of the field (for example `"<b>AAA</b>"`) is displayed to the user rather than the interpreted HTML (for example `"AAA"`). Setting `escapeHTML` false will instead force HTML values in a textAreaItem to be interpreted by the browser in that situation.
    Overrides:
      `setEscapeHTML` in class `FormItem`
    Parameters:
      `escapeHTML` - New escapeHTML value. Default value is true
    Returns:
      `TextAreaItem` instance, for chaining setter calls
    See Also:
      - `Appearance overview and related methods`

  - ### getEscapeHTML

    public Boolean getEscapeHTML()
    By default HTML characters will be escaped when `canEdit` is false and `readOnlyDisplay` is "static", so that the raw value of the field (for example `"<b>AAA</b>"`) is displayed to the user rather than the interpreted HTML (for example `"AAA"`).

    Unless the HTML5 `placeholder` attribute is used to display the hint (see `usePlaceholderForHint`), the value of the <input> element for this item will be set to the hint whenever this item is not focused. Also, when displaying the hint, the CSS style of the data element will be set to the `textBoxStyle` with the suffix "Hint" appended to it; or, if the item is disabled, the suffix "DisabledHint" will be used. In `RTL mode` when `showRTL` is `true`, an additional "RTL" suffix will be appended; i.e. the CSS style of the data element when the hint is displayed will be the `textBoxStyle` plus "HintRTL" or "DisabledHintRTL".

    To change this attribute after being drawn, it is necessary to call `FormItem.redraw()` or redraw the form.

    ### Styling the in-field hint

    The in-field hint can be styled with CSS for the `textBoxStyle` + "Hint" / "HintRTL" / "DisabledHint" / "DisabledHintRTL" styles. For example, if this item's `textBoxStyle` is set to "mySpecialItem", then changing the hint color to blue can be accomplished with the following CSS:

        .mySpecialItemHint,
         .mySpecialItemHintRTL,
         .mySpecialItemDisabledHint,
         .mySpecialItemDisabledHintRTL {

    Does the current formItem support native cut and paste events?

    This attribute only applies to freeform text entry fields such as `TextItem` and `TextAreaItem`, and only if `changeOnKeypress` is true. If true, developers can detect the user editing the value via cut or paste interactions (triggered from keyboard shortcuts or the native browser menu options) using the `FormItem.isCutEvent()` and `FormItem.isPasteEvent()` methods. This allows custom cut/paste handling to be added to the various change notification flow methods including `FormItem.change()`, and `FormItem.transformInput()`.

    Overrides:
      `setSupportsCutPasteEvents` in class `FormItem`
    Parameters:
      `supportsCutPasteEvents` - New supportsCutPasteEvents value. Default value is true

    Returns:
      Current textBoxStyle value. Default value is "textItem"
    See Also:
      - `FormItemBaseStyle`
      - `Appearance overview and related methods`

  - ### setUsePlaceholderForHint

    public TextAreaItem setUsePlaceholderForHint(boolean usePlaceholderForHint)
    If `showing the hint in field` and if supported by the browser, should the HTML5 `placeholder` attribute be used to display the hint within the field? If set to `false`, then use of the `placeholder` attribute is disabled and an alternative technique to display the hint in-field is used instead.

    The HTML5 `placeholder` attribute is supported in the following major browsers:

    - Chrome 4+
    - Firefox 4+
    - Internet Explorer 10+
    - Safari 5+
    - Opera 11.50+
    - Android 2.1+ `WebView` (used by the stock Browser app and when `packaging with PhoneGap`)
    - Mobile Safari for iOS 3.2+

    In browsers other than the above, in-field hints are implemented via a different technique.

    Note that placeholder behavior is known to differ in Internet Explorer and certain old versions of the above browsers due to a recent change in the HTML5 specification regarding the `placeholder` attribute. Under the old rules, the placeholder is cleared when the element is focused. In the latest HTML5 spec as published by WHATWG, the placeholder is still displayed when the element is focused as long as the value is an empty string.

    ### Styling the placeholder

    While there isn't a standard way to style the placeholder text, Chrome, Firefox, Internet Explorer, and Safari provide vendor-prefixed pseudo-classes and/or pseudo-elements that can be used in CSS selectors:

    Browser | Pseudo-class or pseudo-element
    --- | ---
    Chrome, Safari | `::-webkit-input-placeholder`
    Firefox 4 - 18 | `:-moz-placeholder`
    Firefox 19+ | `::-moz-placeholder`
    Internet Explorer | `:-ms-input-placeholder`

    Note that unlike other browsers, Firefox 19+ applies opacity:0.4 to the placeholder text. See Bug 556145 - Placeholder text default style should use opacity instead of GrayText

    Because browsers are required to ignore the entire rule if a selector is invalid, separate rules are needed for each browser. For example:

        ::-webkit-input-placeholder {
             color: blue;
             opacity: 1;
         }
         :-moz-placeholder {
             color: blue;
             opacity: 1;
         }
         ::-moz-placeholder {
             color: blue;
             opacity: 1;
         }
         :-ms-input-placeholder {
             color: blue;
             opacity: 1;
         }

    If using Sass, it may be useful to utilize Sass' parent selector feature. For example:

        .myCustomItem,
         .myCustomItemRTL,
         .myCustomItemDisabled,
         .myCustomItemDisabledRTL,
         .myCustomItemError,
         .myCustomItemErrorRTL,
         .myCustomItemFocused,
         .myCustomItemFocusedRTL,
         .myCustomItemHint,
         .myCustomItemHintRTL,
         .myCustomItemDisabledHint,
         .myCustomItemDisabledHintRTL {
             // ...

             &::-webkit-input-placeholder {
                 color: blue;
                 opacity: 1;
             }
             &:-moz-placeholder {
                 color: blue;
                 opacity: 1;
             }
             &::-moz-placeholder {
                 color: blue;
                 opacity: 1;
             }
             &:-ms-input-placeholder {
                 color: blue;
                 opacity: 1;
             }
         }

    If using Compass, the `input-placeholder` mixin that was added in version 1.0 can further simplify the code to style the placeholder text For example:

        .myCustomItem,
         .myCustomItemRTL,
         .myCustomItemDisabled,
         .myCustomItemDisabledRTL,
         .myCustomItemError,
         .myCustomItemErrorRTL,
         .myCustomItemFocused,
         .myCustomItemFocusedRTL,
         .myCustomItemHint,
         .myCustomItemHintRTL,
         .myCustomItemDisabledHint,
         .myCustomItemDisabledHintRTL {
             // ...

             @include input-placeholder {
                 color: blue;
                 opacity: 1;
             }
         }

    ### Accessibility concerns

    The HTML5 specification notes that a placeholder should not be used as a replacement for a title. The placeholder is intended to be a short hint that assists the user who is entering a value into the empty field. The placeholder can be mistaken by some users for a pre-filled value, particularly in Internet Explorer because the same color is used, and the placeholder text color may provide insufficient contrast, particularly in Firefox 19+ because of the default 0.4 opacity. Furthermore, not having a title reduces the hit area available for setting focus on the item.

    Note : This is an advanced setting

    Parameters:
      `usePlaceholderForHint` - New usePlaceholderForHint value. Default value is true
    Returns:
      `TextAreaItem` instance, for chaining setter calls
    See Also:
      - `FormItem.setHint(java.lang.String)`

             &::-webkit-input-placeholder {
                 color: blue;
                 opacity: 1;
             }
             &:-moz-placeholder {

             &::-moz-placeholder {

                 opacity: 1;
             }
         }

    If using Compass, the `input-placeholder` mixin that was added in version 1.0 can further simplify the code to style the placeholder text For example:

        .myCustomItem,
         .myCustomItemRTL,
         .myCustomItemDisabled,
         .myCustomItemDisabledRTL,
         .myCustomItemError,
         .myCustomItemErrorRTL,
         .myCustomItemFocused,
         .myCustomItemFocusedRTL,
         .myCustomItemHint,
         .myCustomItemHintRTL,
         .myCustomItemDisabledHint,
         .myCustomItemDisabledHintRTL {
             // ...

             @include input-placeholder {
                 color: blue;
                 opacity: 1;
             }
         }

    ### Accessibility concerns

    The HTML5 specification notes that a placeholder should not be used as a replacement for a title. The placeholder is intended to be a short hint that assists the user who is entering a value into the empty field. The placeholder can be mistaken by some users for a pre-filled value, particularly in Internet Explorer because the same color is used, and the placeholder text color may provide insufficient contrast, particularly in Firefox 19+ because of the default 0.4 opacity. Furthermore, not having a title reduces the hit area available for setting focus on the item.
    Returns:
      Current usePlaceholderForHint value. Default value is true
    See Also:
      - `FormItem.getHint()`
      - `Appearance overview and related methods`

  - ### setWidth

    public TextAreaItem setWidth(int width)
    default width of this item
    Overrides:
      `setWidth` in class `FormItem`
    Parameters:
      `width` - New width value. Default value is 150
    Returns:
      `TextAreaItem` instance, for chaining setter calls
    See Also:
      - `Appearance overview and related methods`

  - ### getWidth

    public int getWidth()
    default width of this item
    Overrides:
      `getWidth` in class `FormItem`
    Returns:
      Current width value. Default value is 150
    See Also:
      - `Appearance overview and related methods`

  - ### deselectValue

    public void deselectValue()
    If this item currently has focus, clear the current selection. leaving focus in the item. Has no effect if the item is undrawn or unfocused. Only applies to text-based items.

  - ### deselectValue

    public void deselectValue(Boolean start)
    If this item currently has focus, clear the current selection. leaving focus in the item. Has no effect if the item is undrawn or unfocused. Only applies to text-based items.
    Parameters:
      `start` - By default the text insertion cursor will be moved to the end of the current value - pass in this parameter to move to the start instead

  - ### getEnteredValue

    public String getEnteredValue()
    Returns the raw text value that currently appears in the text field, which can differ from `FormItem.getValue()` in various cases - for example:
    - for items that constrain the value range, such as a `DateItem` with `enforceDate`:true, or a `ComboBoxItem` with `addUnknownValues`:false
    - for items with a defined valueMap or edit value formatter and parser functions which converts display value to data value
    - while the item has focus if `changeOnKeypress` is false
    Returns:
      current entered value

  - ### getSelectionRange

    public int[] getSelectionRange()
    For text-based items, this method returns the indices of the start/end of the current selection if the item currently has the focus. In browsers other than Internet Explorer 6-9, if this item does not have focus, then this method returns the indices of the start/end of the selection the last time that this item had focus. In IE 6-9, returns null if the item does not have focus.

    In all browsers, clicking anywhere outside of the item causes the item to lose focus; hence, in IE 6-9, this method will not work in other components' event handlers for certain events. For example, within the `click()` handler of a button, this item will have already lost focus, so in IE 6-9, this method will return null if called within the button's click() handler. One cross-browser solution to this issue is to save the selection range for later in a `mouseDown()` or `mouseOver()` handler.

    Notes:

    - In browsers other than IE 6-9, calling `setValue()` or otherwise changing the `entered value` invalidates the past selection range.
    - The returned indices are indices within the entered value rather than the item's value as returned by `getValue()`. The distinction is particularly important for `TextAreaItem`s because browsers normalize the line endings in the `<textarea>` element's value. Internet Explorer 6, 7, and 8 convert line endings to "\r\n" while other browsers convert line endings to "\n" as specified by the HTML5 standard.
    Returns:
      2 element array showing character index of the current or past selection's start and end points within this item's `entered value`. In IE 6-9, returns null if the item does not have focus.

  - ### selectValue

    public void selectValue()
    Put focus in this item and select the entire value. Only applies to text based items

  - ### setSelectionRange

    public void setSelectionRange(int start, int end)
    Puts focus into this form item and selects characters between the given indices. Only applies to drawn text based items.
    Parameters:
      `start` - selection starting character index
      `end` - end of selection character index

  - ### transformPastedValue

    public String transformPastedValue(FormItem item, DynamicForm form, String pastedValue)
    Notification fired in response to a clipboard "paste" event on freeform text items, giving developers an opportunity to reformat the pasted text. The `pastedValue` argument contains the text pasted from the clipboard. This method should return the text value to actually insert into the input element.
    Parameters:
      `item` - Item into which the user pasted a value
      `form` - Pointer to the item's form
      `pastedValue` - Pasted text value
    Returns:
      Reformatted version of the pasted text.

  - ### setDefaultProperties

    public static void setDefaultProperties(TextAreaItem textAreaItemProperties)
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

    Parameters:
      `textAreaItemProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`

  - ### setWrap

    public void setWrap(TextAreaWrap wrap)
    Text wrapping style.
    Parameters:
      `wrap` - wrap Default value is `TextAreaWrap.SOFT`

  - ### getWrap

    public TextAreaWrap getWrap()
    Text wrapping style.
    Returns:
      TextAreaWrap

  - ### getValueAsString

    public String getValueAsString()
    Return the value tracked by this form item.
    Returns:
      value of this element
