Constructor Summary
ControlSwingElement(java.lang.Object _visual)
          Instantiates an object that wrapps a Swing JComponent of this type.
 
Method Summary
 java.awt.Component getComponent()
          Returns the component of this ControlElement, the one that is added to a container.
 java.lang.String getPropertyInfo(java.lang.String _property)
          Returns information about a given property.
 java.util.ArrayList<java.lang.String> getPropertyList()
          Returns the list of all properties that can be set for this ControlElement.
 Value getValue(int _index)
          Gets the value of any internal variable.
 java.awt.Component getVisual()
          Returns the visual component of this ControlElement, the one you can configure graphically.
 Value parseConstant(java.lang.String _propertyType, java.lang.String _value)
          Checks if a value can be considered a valid constant value for a property If not, it returns null, meaning the value can be considered to be a GroupVariable or a primitive constant.

Constructor Detail

ControlSwingElement

public ControlSwingElement(java.lang.Object _visual)
Instantiates an object that wrapps a Swing JComponent of this type. If an object of an appropriate class is provided, it is used as the visual.

Parameters:
_visual - The javax.swing.JComponent to be wrapped
Method Detail

getVisual

public final java.awt.Component getVisual()
Returns the visual component of this ControlElement, the one you can configure graphically.

Overrides:
getVisual in class ControlElement

getComponent

public java.awt.Component getComponent()
Returns the component of this ControlElement, the one that is added to a container.

Overrides:
getComponent in class ControlElement

getPropertyList

public java.util.ArrayList<java.lang.String> getPropertyList()
Returns the list of all properties that can be set for this ControlElement. Subclasses that add properties should extend this table. Order is crucial here: Both for the presentation in an editor (f.i. ViewElement) and for the setValue() method.

Specified by:
getPropertyList in class ControlElement

getPropertyInfo

public java.lang.String getPropertyInfo(java.lang.String _property)
Returns information about a given property. Subclasses that add properties should extend this table.
  • The first keyword is ALWAYS the type.
  • The keyword CONSTANT applies to properties that can not be changed using the setValue() methods
  • The keyword BASIC is used by Ejs to group properties to the left hand side of the property editor
  • The keyword HIDDEN is used by Ejs so that it does not display an entry in the editor field

    Specified by:
    getPropertyInfo in class ControlElement

  • parseConstant

    public Value parseConstant(java.lang.String _propertyType,
                               java.lang.String _value)
    Checks if a value can be considered a valid constant value for a property If not, it returns null, meaning the value can be considered to be a GroupVariable or a primitive constant. This method implements more cases than really needed for the base class. This is in order to save repetitions in swing subclasses.

    Overrides:
    parseConstant in class ControlElement
    Parameters:
    String - _property The property name
    String - _value The proposed value for the property

    setValue

    public void setValue(int _index,
                         Value _value)
    Sets the value of the registered variables. Subclasses with internal values should extend this

    Overrides:
    setValue in class ControlElement
    Parameters:
    _index - A keyword index that distinguishes among variables
    _value - The object holding the value for the variable.

    setDefaultValue

    public void setDefaultValue(int _index)
    Overrides:
    setDefaultValue in class ControlElement

    getValue

    public Value getValue(int _index)
    Gets the value of any internal variable. Subclasses with internal values should extend this

    Overrides:
    getValue in class ControlElement
    Parameters:
    _index - A keyword index that distinguishes among variables
    Returns:
    Value _value The object holding the value for the variable.
