public interface FormItemStyling
 Form items
 written out by a DynamicForm with  itemLayout:"table" are written into
 table cells. A formItem can govern the appearance of these cells using properties such as 
 FormItem.cellStyle,
 FormItem.cellHeight.
 These properties have no effect for formItems rendered outside a form (for example the during
 grid editing), or if
 itemLayout is "absolute". 
 If a formItem is showing a picker icon, the picker
 icon and text box will be written into an element referred to as the control table. Styling
 applied to this element (via FormItem.controlStyle) will
 extend around both the text box and the picker (but not other icons, hints, etc). The control
 table is not written out if the pickerIcon is not visible except in the case where the FormItem.showPickerIconOnFocus is true, and the item does not have focus, or if a developer
 explicitly sets FormItem.alwaysShowControlBox to true. 
 The textBox of an item is the area containing its
 main textual content. This may natively be achieved as a data element (such as an <input
 ...>), or a static DOM element. See FormItem.textBoxStyle, and
 related FormItem.readOnlyTextBoxStyle and FormItem.printTextBoxStyle for styling options.  See also FormItem.shouldApplyHeightToTextBox() for a discussion on sizing the text box. 
 Any visible
 valueIcon will be
 rendered inside the text box for  static items, or adjacent to it for items where the text is
 editable (such as TextItem). Explicit styling
 for the valueIcon can be specified via the FormItem.getValueIconStyle() method. 
 FormItems can also show explicitly defined FormItem.icons. By default these 
 show up next to the item, outside its text box and control table / after the picker icon (if present),
 though inline
 positioning is also supported for some cases. Their appearance and behavior are heavily
 customizable - see FormItemIcon.baseStyle, FormItemIcon.src and related properties. 
 FormItem hints may be written out as
 static text after any icons, and styled according to the FormItem.hintStyle - or where
 supported, written directly into the text box with styling derived from the textBoxStyle plus a
 suffix of "Hint". (See TextItem.showHintInField).
 
 In addition to this, form items may show validation error icons or text  (see DynamicForm.showInlineErrors,
 FormItem.showErrorIcon and FormItem.showErrorText). The
 position of these error indicators is controlled by DynamicForm.errorOrientation.
 
 Most formItem user-interface elements support stateful styling - showing a different
 appearance for focused,
 over, disabled and error states. 
 Default
 styling for items will vary by skin, and note that subclasses of  FormItem may have additional
 styling properties not explicitly called out here.
 Developers performing global styling
 modifications for formItems should also be aware of compound items (such as DateItem) which achieve their user interface by
 embedding simpler items in an outer structure. See CompoundFormItem_skinning.
