BasicOptionPaneUI JDK 1.6)

Methods

protected void addButtonComponents (Container container, Object buttons, int initialIndex)

Creates the appropriate object to represent each of the objects in buttons and adds it to container.

Creates the appropriate object to represent each of the objects in
buttons and adds it to container. This
differs from addMessageComponents in that it will recurse on
buttons and that if button is not a Component
it will create an instance of JButton.

protected void addIcon (Container top)

Creates and adds a JLabel representing the icon returned from getIcon to top.

Creates and adds a JLabel representing the icon returned from
getIcon to top. This is messaged from
createMessageArea

protected void addMessageComponents (Container container, GridBagConstraints cons, Object msg, int maxll, boolean internallyCreated)

Creates the appropriate object to represent msg and places it into container.

Creates the appropriate object to represent msg and
places it into container. If msg is an
instance of Component, it is added directly, if it is an Icon,
a JLabel is created to represent it, otherwise a JLabel is
created for the string, if d is an Object[], this
method will be recursively invoked for the children.
internallyCreated is true if Objc is an instance
of Component and was created internally by this method (this is
used to correctly set hasCustomComponents only if !internallyCreated).

protected void burstStringInto (Container c, String d, int maxll)

Recursively creates new JLabel instances to represent d.

Recursively creates new JLabel instances to represent d.
Each JLabel instance is added to c.

public boolean contains (JComponent c, int x, int y) [Inherited From ComponentUI]

Returns true if the specified x,y location is contained within the look and feel's defined shape of the specified component.

Returns true if the specified x,y location is
contained within the look and feel's defined shape of the specified
component. x and y are defined to be relative
to the coordinate system of the specified component. Although
a component's bounds is constrained to a rectangle,
this method provides the means for defining a non-rectangular
shape within those bounds for the purpose of hit detection.
Parameters:
- c - the component where the x,y location is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
- x - the x coordinate of the point
- y - the y coordinate of the point

public boolean containsCustomComponents (JOptionPane op) [Specified in OptionPaneUI]

Returns true if in the last call to validateComponent the message or buttons contained a subclass of Component.

protected ActionListener createButtonActionListener (int buttonIndex)

protected Container createButtonArea ()

Creates and returns a Container containing the buttons.

Creates and returns a Container containing the buttons. The buttons
are created by calling getButtons.

protected LayoutManager createLayoutManager ()

protected Container createMessageArea ()

Messaged from installComponents to create a Container containing the body of the message.

Messaged from installComponents to create a Container containing the
body of the message. The icon is the created by calling
addIcon.

protected PropertyChangeListener createPropertyChangeListener ()

protected Container createSeparator ()

publicstatic ComponentUI createUI (JComponent x) [Overrides ComponentUI]

Creates a new BasicOptionPaneUI instance.

public Accessible getAccessibleChild (JComponent c, int i) [Inherited From ComponentUI]

Returns the ith Accessible child of the object.

Returns the ith Accessible child of the object. UIs might need to override this if they present areas on the screen that can be viewed as components, but actual components are not used for presenting those areas.

Note: As of v1.3, it is recommended that developers call Component.AccessibleAWTComponent.getAccessibleChild() instead of this method.
Returns: the ith Accessible child of the object
Parameters:
- i - zero-based index of child
See Also: ComponentUI.getAccessibleChildrenCount(javax.swing.JComponent),

public int getAccessibleChildrenCount (JComponent c) [Inherited From ComponentUI]

Returns the number of accessible children in the object.

Returns the number of accessible children in the object. If all
of the children of this object implement Accessible,
this
method should return the number of children of this object.
UIs might wish to override this if they present areas on the
screen that can be viewed as components, but actual components
are not used for presenting those areas.

Note: As of v1.3, it is recommended that developers call
Component.AccessibleAWTComponent.getAccessibleChildrenCount() instead
of this method.
Returns: the number of accessible children in the object
See Also: ComponentUI.getAccessibleChild(javax.swing.JComponent, int),

public int getBaseline (JComponent c, int width, int height) [Inherited From ComponentUI]

Returns the baseline.

Returns the baseline. The baseline is measured from the top of the component. This method is primarily meant for LayoutManagers to align components along their baseline. A return value less than 0 indicates this component does not have a reasonable baseline and that LayoutManagers should not align this component on its baseline.

This method returns -1. Subclasses that have a meaningful baseline should override appropriately.
Returns: baseline or a value < 0 indicating there is no reasonable baseline
Parameters:
- c - JComponent baseline is being requested for
- width - the width to get the baseline for
- height - the height to get the baseline for
Throws:
- NullPointerException - if c is null
- IllegalArgumentException - if width or height is < 0
Since: 1.6
See Also: JComponent.getBaseline(int,int),

public BaselineResizeBehavior getBaselineResizeBehavior (JComponent c) [Inherited From ComponentUI]

Returns an enum indicating how the baseline of he component changes as the size changes.

protected Object getButtons ()

Returns the buttons to display from the JOptionPane the receiver is providing the look and feel for.

protected Icon getIcon ()

Returns the icon from the JOptionPane the receiver is providing the look and feel for, or the default icon as returned from getDefaultIcon.

protected Icon getIconForType (int messageType)

Returns the icon to use for the passed in type.

protected int getInitialValueIndex ()

Returns the initial index into the buttons to select.

pack-private InputMap getInputMap (int condition)

protected int getMaxCharactersPerLineCount ()

Returns the maximum number of characters to place on a line.

public Dimension getMaximumSize (JComponent c) [Inherited From ComponentUI]

Returns the specified component's maximum size appropriate for the look and feel.

Returns the specified component's maximum size appropriate for
the look and feel. If null is returned, the maximum
size will be calculated by the component's layout manager instead
(this is the preferred approach for any component with a specific
layout manager installed). The default implementation of this
method invokes getPreferredSize and returns that value.
Returns: a Dimension object or null
Parameters:
- c - the component whose maximum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
See Also: JComponent.getMaximumSize(), LayoutManager2.maximumLayoutSize(java.awt.Container),

protected Object getMessage ()

Returns the message to display from the JOptionPane the receiver is providing the look and feel for.

public Dimension getMinimumOptionPaneSize ()

Returns the minimum size the option pane should be.

public Dimension getMinimumSize (JComponent c) [Inherited From ComponentUI]

Returns the specified component's minimum size appropriate for the look and feel.

Returns the specified component's minimum size appropriate for
the look and feel. If null is returned, the minimum
size will be calculated by the component's layout manager instead
(this is the preferred approach for any component with a specific
layout manager installed). The default implementation of this
method invokes getPreferredSize and returns that value.
Returns: a Dimension object or null
Parameters:
- c - the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
See Also: JComponent.getMinimumSize(), LayoutManager.minimumLayoutSize(java.awt.Container), ComponentUI.getPreferredSize(javax.swing.JComponent),

public Dimension getPreferredSize (JComponent c) [Overrides ComponentUI]

If c is the JOptionPane the receiver is contained in, the preferred size that is returned is the maximum of the preferred size of the LayoutManager for the JOptionPane, and getMinimumOptionPaneSize.

pack-privatestatic void loadActionMap (LazyActionMap map)

public void paint (Graphics g, JComponent c) [Inherited From ComponentUI]

Paints the specified component appropriate for the look and feel.

Paints the specified component appropriate for the look and feel.
This method is invoked from the ComponentUI.update method when
the specified component is being painted. Subclasses should override
this method and use the specified Graphics object to
render the content of the component.
Parameters:
- g - the Graphics context in which to paint
- c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
See Also: ComponentUI.update(java.awt.Graphics, javax.swing.JComponent),

protected void resetInputValue ()

Sets the input value in the option pane the receiver is providing the look and feel for based on the value in the inputComponent.

public void selectInitialValue (JOptionPane op) [Specified in OptionPaneUI]

protected void uninstallDefaults ()

protected void uninstallKeyboardActions ()

protected void uninstallListeners ()

public void uninstallUI (JComponent c) [Overrides ComponentUI]

Removes the receiver from the L&F controller of the passed in split pane.

public void update (Graphics g, JComponent c) [Inherited From ComponentUI]

Notifies this UI delegate that it's time to paint the specified component.

Notifies this UI delegate that it's time to paint the specified
component. This method is invoked by JComponent
when the specified component is being painted.
By default this method will fill the specified component with
its background color (if its opaque property is
true) and then immediately call paint.
In general this method need not be overridden by subclasses;
all look-and-feel rendering code should reside in the paint
method.
Parameters:
- g - the Graphics context in which to paint
- c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
