- Method Detail
  - getPanel
```
InputPanel<?,?> getPanel()
```
    Gets the input panel intended to house the widget.
  - getModule
```
Module getModule()
```
    Gets the module's associated module instance.
  - getItem
```
ModuleItem<?> getItem()
```
    Gets the module input's associated item descriptor.
  - getObjectPool
```
List<?> getObjectPool()
```
    Gets the available objects for use with the widget. For example, ObjectWidgets typically display a dropdown combo box providing multiple choice selection between these objects.
    Note that this list does not represent a constraint in allowed widget values, but rather provides a list of possibilities in cases where the realm of values is not defined by the type in some other way.
    
    See Also:
    ObjectWidget
  - getWidgetLabel
```
String getWidgetLabel()
```
    Gets the text to use when labeling this widget. The linked item's label will be given if available (i.e., BasicDetails.getLabel()). Otherwise, a capitalized version of the item's name is given (i.e., Named.getName()).
  - isStyle
```
boolean isStyle(String style)
```
    Gets whether the widget is the given style. A widget may have multiple styles separated by commas, so this method is more correct than using style.equals(getItem().getWidgetStyle()).
  - getValue
```
Object getValue()
```
    Gets the current value of the module input.
    In the case of inputs with a limited set of choices (i.e., ChoiceWidgets and ObjectWidgets), this method ensures the value is in the set; if not, it returns the first item of the set.
  - setValue
```
void setValue(Object value)
```
    Sets the current value of the module input.
  - callback
```
void callback()
```
    Executes the callback associated with this widget's associated input.
  - getMin
```
Number getMin()
```
    Gets the minimum value for the module input.
    
    Returns:
    The minimum value, or null if the type is unbounded.
  - getMax
```
Number getMax()
```
    Gets the maximum value for the module input.
    
    Returns:
    The maximum value, or null if the type is unbounded.
  - getSoftMin
```
Number getSoftMin()
```
    Gets the "soft" minimum value for the module input.
    
    Returns:
    The "soft" minimum value, or getMin() if none.
    See Also:
    ModuleItem.getSoftMinimum()
  - getSoftMax
```
Number getSoftMax()
```
    Gets the "soft" maximum value for the module input.
    
    Returns:
    The "soft" maximum value, or getMax() if none.
    See Also:
    ModuleItem.getSoftMaximum()
  - getStepSize
```
Number getStepSize()
```
    Gets the step size between values for the module input.
    
    Returns:
    The step size, or 1 by default.
  - getChoices
```
String[] getChoices()
```
    Gets the multiple choice list for the module input.
    
    Returns:
    The available choices, or an empty list if not multiple choice.
    See Also:
    ChoiceWidget
  - getText
```
String getText()
```
    Gets the input's value rendered as a string.
    
    Returns:
    String representation of the input value, or the empty string if the value is null or the null character ('\0').
  - isMessage
```
boolean isMessage()
```
    Gets whether the input is a message.
    
    See Also:
    ItemVisibility.MESSAGE
  - isText
```
boolean isText()
```
    Gets whether the input is a text type (i.e., String, Character or char.
  - isCharacter
```
boolean isCharacter()
```
    Gets whether the input is a character type (i.e., Character or char).
  - isNumber
```
boolean isNumber()
```
    Gets whether the input is a number type (e.g., int, float or any Number implementation.
  - isBoolean
```
boolean isBoolean()
```
    Gets whether the input is a boolean type (i.e., Boolean or boolean).
  - isMultipleChoice
```
boolean isMultipleChoice()
```
    Gets whether the input provides a restricted set of choices.
  - isType
```
boolean isType(Class<?> type)
```
    Gets whether the input is compatible with the given type.
  - setInitialized
```
void setInitialized(boolean initialized)
```
    Toggles the widget's initialization state. An initialized widget can be assumed to be an active part of a container InputPanel.
  - isInitialized
```
boolean isInitialized()
```
    Gets the widget's initialization state. An initialized widget can be assumed to be an active part of a container InputPanel.
