Java Source Code / Java Documentation » J2EE » Sofia » com.salmonllc.swing   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    com.salmonllc.swing.SComponentHelper SComponentHelper public class SComponentHelper implements FocusListener,KeyListener,MouseListener,DocumentListener,ActionListener,ItemListener,ListSelectionListener,ChangeListener(Code) Because the SOFIA Swing components extend from standard Swing components, they cannot have a common ancestor. Instead they implement the SComponent interface. This class serves as a base class for all the SComponents in the absence of a real one. It contains helper functions that the various Scomponents need.

See Also:   SComponentHelper.acceptValue() acceptValue public void acceptValue()(Code) Components update the model when they lose focus. Just in case you want to update the model on a component with focus programatically like if the user presses a hot key, call accept value on a component to get it to move the value to the model. actionPerformed public void actionPerformed(ActionEvent e)(Code) Invoked when an action occurs. addKeyboardMappings public void addKeyboardMappings(JComponent comp)(Code) Adds keyboard mappings to the component. Sets shift+delete, shift+insert, control+insert to cut/paste/copy and sets the tab to a traversal key for a text area. Parameters:   comp - addPopupMenu public void addPopupMenu(JComponent comp)(Code) Adds a right click cut/copy/paste menu to the component addValueChangedListener public void addValueChangedListener(ValueChangedListener l)(Code) This method adds a listener the will be notified when the value in this component changes. Parameters:   l - The listener to add. applySkin public static void applySkin(Skin sk, Container p)(Code) Applies a SOFIA skin to the look and feel defaults for the application changedUpdate public void changedUpdate(DocumentEvent e)(Code) See Also:   DocumentListener.changedUpdate(DocumentEvent) focusGained public void focusGained(FocusEvent e)(Code) See Also:   FocusListener.focusGained(FocusEvent) focusLost public void focusLost(FocusEvent e)(Code) See Also:   FocusListener.focusLost(FocusEvent) getMaxLength int getMaxLength()(Code) getMenu public JPopupMenu getMenu()(Code) Returns the right click popup menu for this component getParentFrame public static JFrame getParentFrame(JComponent comp)(Code) Finds the parent frame of the component or null if there isn't one insertUpdate public void insertUpdate(DocumentEvent e)(Code) See Also:   DocumentListener.insertUpdate(DocumentEvent) isDataDirty public boolean isDataDirty()(Code) Test to see if the data in the component is dirty (changed, but not moved to the model) isMenuVisible public boolean isMenuVisible()(Code) Components may have a right click cut/copy/paste menu. This method indicates that whether or not it is currently visible itemStateChanged public void itemStateChanged(ItemEvent e)(Code) Invoked when an item has been selected or deselected by the user. The code written for this method performs the operations that need to occur when an item is selected (or deselected). keyPressed public void keyPressed(KeyEvent e)(Code) Invoked when a key has been pressed. See the class description for KeyEvent for a definition of a key pressed event. keyReleased public void keyReleased(KeyEvent e)(Code) Invoked when a key has been released. See the class description for KeyEvent for a definition of a key released event. keyTyped public void keyTyped(KeyEvent e)(Code) Invoked when a key has been typed. See the class description for KeyEvent for a definition of a key typed event. mouseClicked public void mouseClicked(MouseEvent e)(Code) Invoked when the mouse button has been clicked (pressed and released) on a component. mouseEntered public void mouseEntered(MouseEvent e)(Code) Invoked when the mouse enters a component. mouseExited public void mouseExited(MouseEvent e)(Code) Invoked when the mouse exits a component. mousePressed public void mousePressed(MouseEvent e)(Code) Invoked when a mouse button has been pressed on a component. mouseReleased public void mouseReleased(MouseEvent e)(Code) Invoked when a mouse button has been released on a component. notifyValueChangedListeners public void notifyValueChangedListeners(ValueChangedEvent evt)(Code) Called from the framework when value changed listeners for the component need to be fired Parameters:   evt - removeKeyboardMappings public void removeKeyboardMappings(JComponent comp)(Code) Removes the keyboard mappings from a component added with addKeyboardMappings removePopupMenu public void removePopupMenu()(Code) Removes a right click menu from the component removeUpdate public void removeUpdate(DocumentEvent e)(Code) See Also:   DocumentListener.removeUpdate(DocumentEvent) removeValueChangedListener public void removeValueChangedListener(ValueChangedListener l)(Code) This method removes a listener from the list that will be notified if the text in the component changes. Parameters:   l - The listener to remove. setAllComponentsEnabled public static void setAllComponentsEnabled(Container cont, boolean enabled)(Code) Enables or disables all components in the container setAllComponentsToFocusable public static void setAllComponentsToFocusable(Container cont)(Code) Sets all components in the container to focusable, skipping ones that are currently set to false. This method is mainly used as a work around for a bug in JDK 1.4 with respect to applets. Without explicitly calling setFocusable(true) on each component, they do not respond to the tab key. setAllComponentsToFocusable public static void setAllComponentsToFocusable(Container cont, boolean skipFalse)(Code) Sets all components in the container to focusable, and will skip ones that are currently set to false depending on the argument passed. This method is mainly used as a work around for a bug in JDK 1.4 with respect to applets. Without explicitly calling setFocusable(true) on each component, they do not respond to the tab key. setCursor public static void setCursor(JComponent comp, Cursor cur)(Code) Sets the mouse cursor for a component setDataDirty public void setDataDirty(boolean dataDirty)(Code) Sets the data dirty flag for the component (data is changed, but not moved to the model) setDefaultCursor public static void setDefaultCursor(JComponent comp)(Code) Sets the default mouse cursor for this component setMaxLength void setMaxLength(int maxLength)(Code) setWaitCursor public static void setWaitCursor(JComponent comp)(Code) Sets the wait mouse cursor for this component stateChanged public void stateChanged(ChangeEvent e)(Code) Invoked when the target of the listener has changed its state. Parameters:   e - a ChangeEvent object valueChanged public void valueChanged(ListSelectionEvent e)(Code) Called whenever the value of the selection changes. Parameters:   e - the event that characterizes the change. valuesEqual public static boolean valuesEqual(Object newValue, Object oldValue)(Code) Utility method that compares two values to see if they are equal Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
