Field Detail

preferredSize

public Parameter preferredSize

The preferred size of the Swing component. It would be a matrix of 2 integers, such as [100, 20]. It is ignored if any integer is less than 0.

Constructor Detail

GUIProperty

public GUIProperty(NamedObj container,
                   java.lang.String name)
            throws IllegalActionException,
                   NameDuplicationException

Construct a GUI property with the given name contained by the specified entity. The container argument must not be null, or a NullPointerException will be thrown. This attribute will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string. Increment the version of the workspace.

Parameters:

container - The container.

name - The name of this attribute.

Throws:

IllegalActionException - If the attribute is not of an acceptable class for the container, or if the name contains a period.

NameDuplicationException - If the name coincides with an attribute already in the container.

GUIProperty

public GUIProperty(NamedObj container,
                   java.lang.String name,
                   javax.swing.JComponent component)
            throws IllegalActionException,
                   NameDuplicationException

Construct a GUI property with the given name contained by the specified entity with the given Java Swing component. The container argument must not be null, or a NullPointerException will be thrown. This attribute will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string. Increment the version of the workspace.

Parameters:

container - The container.

name - The name of this attribute.

component - The Java Swing component.

Throws:

IllegalActionException - If the attribute is not of an acceptable class for the container, or if the name contains a period.

NameDuplicationException - If the name coincides with an attribute already in the container.

GUIProperty

public GUIProperty(NamedObj container,
                   java.lang.String name,
                   javax.swing.JComponent component,
                   java.lang.Object constraint)
            throws IllegalActionException,
                   NameDuplicationException

Construct a GUI property with the given name contained by the specified entity with the given Java Swing component and the given layout constraint. The container argument must not be null, or a NullPointerException will be thrown. This attribute will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string. Increment the version of the workspace.

Parameters:

container - The container.

name - The name of this attribute.

component - The Java Swing component.

constraint - The layout constraint.

Throws:

IllegalActionException - If the attribute is not of an acceptable class for the container, or if the name contains a period.

NameDuplicationException - If the name coincides with an attribute already in the container.

GUIProperty

public GUIProperty(NamedObj container,
                   java.lang.String name,
                   java.lang.Object constraint)
            throws IllegalActionException,
                   NameDuplicationException

Construct a GUI property with the given name contained by the specified entity with the given layout constraint. The container argument must not be null, or a NullPointerException will be thrown. This attribute will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string. Increment the version of the workspace.

Parameters:

container - The container.

name - The name of this attribute.

constraint - The layout constraint.

Throws:

IllegalActionException - If the attribute is not of an acceptable class for the container, or if the name contains a period.

NameDuplicationException - If the name coincides with an attribute already in the container.

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

React to a change in an attribute. This method is called by a contained attribute when its value changes. If the changed attribute is preferredSize, then the preferred size of the Swing component in this GUI property is adjusted accordingly.

Overrides:

attributeChanged in class NamedObj

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the change is not acceptable to this container (not thrown in this base class).

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException

Clone the property into the specified workspace.

Overrides:

clone in class Attribute

Parameters:

workspace - The workspace in to which the object is cloned.

Returns:

A new property

Throws:

java.lang.CloneNotSupportedException - If a derived class contains an attribute that cannot be cloned.

See Also:

NamedObj.exportMoML(Writer, int, String), NamedObj.setDeferringChangeRequests(boolean)

getComponent

public javax.swing.JComponent getComponent()

Return the Swing component.

Returns:

The Swing component.

setContainer

public void setContainer(NamedObj container)
                  throws IllegalActionException,
                         NameDuplicationException

Specify the container NamedObj, adding this attribute to the list of attributes in the container. If the container already contains an attribute with the same name, then throw an exception and do not make any changes. Similarly, if the container is not in the same workspace as this attribute, throw an exception. If this attribute is already contained by the NamedObj, do nothing. If the attribute already has a container, remove this attribute from its attribute list first. Otherwise, remove it from the directory of the workspace, if it is there. If the argument is null, then remove it from its container. It is not added to the workspace directory, so this could result in this object being garbage collected. Note that since an Attribute is a NamedObj, it can itself have attributes. However, recursive containment is not allowed, where an attribute is an attribute of itself, or indirectly of any attribute it contains. This method is write-synchronized on the workspace and increments its version number.

Subclasses may constrain the type of container by overriding setContainer(NamedObj).

Overrides:

setContainer in class Attribute

Parameters:

container - The container to attach this attribute to..

Throws:

IllegalActionException - If this attribute is not of the expected class for the container, or it has no name, or the attribute and container are not in the same workspace, or the proposed container would result in recursive containment.

NameDuplicationException - If the container already has an attribute with the name of this attribute.

See Also:

Attribute.getContainer()

_createComponent

protected abstract javax.swing.JComponent _createComponent()
                                                    throws IllegalActionException

Create a new Java Swing component.

Returns:

A Swing component that can be enclosed in this GUI property.

Throws:

IllegalActionException - Not thrown in this base class.
