void com.arcle.rmt.j2se.swing.ui.ComponentView.addNotify (   )

Template method that initializes child components when this is first added to a parent component. Todo: Move these method calls to a better place. An ideal place is at just after all constructors in the hierarchy had run. Definition at line 124 of file ComponentView.java. References com.arcle.rmt.j2se.swing.ui.ComponentView.initChildren(), com.arcle.rmt.j2se.swing.ui.ComponentView.initialized, and com.arcle.rmt.j2se.swing.ui.ComponentView.layoutChildren().

boolean com.arcle.rmt.j2se.swing.ui.ComponentView.addObservable (  Object  obj  )  [protected]

Adds this as an oberver to the specified object iff the specified object is an instance of observable. Parameters: obj  the observable object. Returns: true if this was added, false otherwise. Definition at line 84 of file ComponentView.java. Referenced by com.arcle.rmt.j2se.swing.ui.ComponentView.setDocument().

boolean com.arcle.rmt.j2se.swing.ui.ComponentView.deleteObservable (  Object  obj  )  [protected]

Removes this from the observers of the specified object iff the specified object is an instance of observable. Parameters: obj  the observable object. Returns: true if this was removed, false otherwise. Definition at line 100 of file ComponentView.java. Referenced by com.arcle.rmt.j2se.swing.ui.ComponentView.setDocument(), and com.arcle.rmt.j2se.swing.ui.ComponentView.update().

JComponent com.arcle.rmt.j2se.swing.ui.ComponentView.getComponent (   )

Returns this as the primary component of the view. Returns: this. Implements com.arcle.rmt.j2se.swing.ui.View. Definition at line 155 of file ComponentView.java.

Controller com.arcle.rmt.j2se.swing.ui.ComponentView.getController (   )

Placeholder method that returns null. Implements com.arcle.rmt.j2se.swing.ui.View. Definition at line 197 of file ComponentView.java.

Document com.arcle.rmt.j2se.swing.ui.ComponentView.getDocument (   )

Returns the current document of the view. Implements com.arcle.rmt.j2se.swing.ui.View. Definition at line 190 of file ComponentView.java. References com.arcle.rmt.j2se.swing.ui.ComponentView._document.

void com.arcle.rmt.j2se.swing.ui.ComponentView.initChildren (   )  [protected]

Strategy method to instantiate all child components. The default implementation does nothing. Definition at line 208 of file ComponentView.java. Referenced by com.arcle.rmt.j2se.swing.ui.ComponentView.addNotify().

boolean com.arcle.rmt.j2se.swing.ui.ComponentView.isDead (   )  [protected]

void com.arcle.rmt.j2se.swing.ui.ComponentView.setDocument (  Document  doc  )

Sets a document into this view, and assigns this as an observer of the document. Afterwards it fires a property change event for the property named document. Parameters: doc  the document to set.
