  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

  Creates a FocusListener which will be added to the combo box.

  Creates a FocusListener which will be added to the combo box.
If this method returns null then it will not be added to the combo box.
Returns: an instance of a FocusListener or null

  Creates an ItemListener which will be added to the combo box.

  Creates an ItemListener which will be added to the combo box. If this method returns null then it will not be added to the combo box.

Subclasses may override this method to return instances of their own ItemEvent handlers.
Returns: an instance of an ItemListener or null

  Creates a KeyListener which will be added to the combo box.

  Creates a KeyListener which will be added to the
combo box. If this method returns null then it will not be added
to the combo box.
Returns: an instance KeyListener or null

  Creates a list data listener which will be added to the ComboBoxModel.

  Creates a list data listener which will be added to the
ComboBoxModel. If this method returns null then
it will not be added to the combo box model.
Returns: an instance of a ListDataListener or null

  Creates the default renderer that will be used in a non-editiable combo box.

  Creates the default renderer that will be used in a non-editiable combo
box. A default renderer will used only if a renderer has not been
explicitly set with setRenderer.
Returns: a ListCellRender used for the combo box
See Also: JComboBox.setRenderer(javax.swing.ListCellRenderer),

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

  Returns an enum indicating how the baseline of the component
changes as the size changes.
Throws:
- NullPointerException - {@inheritDoc}
Since: 1.6

  Return the default size of an empty display area of the combo box using the current renderer and font.

  Return the default size of an empty display area of the combo box using
the current renderer and font.
Returns: the size of an empty display area
See Also: BasicComboBoxUI.getDisplaySize(),

  Returns the calculated size of the display area.

  Returns the calculated size of the display area. The display area is the portion of the combo box in which the selected item is displayed. This method will use the prototype display value if it has been set.

For combo boxes with a non trivial number of items, it is recommended to use a prototype display value to significantly speed up the display size calculation.
Returns: the size of the display area calculated from the combo box items
See Also: JComboBox.setPrototypeDisplayValue(java.lang.Object),

Gets the insets from the JComboBox.

  Creates and initializes the components which make up the aggregate combo box.

  Creates and initializes the components which make up the
aggregate combo box. This method is called as part of the UI
installation process.

Installs the default colors, default font, default renderer, and default editor into the JComboBox.

  Adds keyboard actions to the JComboBox.

  Adds keyboard actions to the JComboBox. Actions on enter and esc are already
supplied. Add more actions as you need them.

  Create and install the listeners for the combo box and its model.
This method is called when the UI is installed.

  Determines if the JComboBox is focus traversable.

  Determines if the JComboBox is focus traversable. If the JComboBox is editable
this returns false, otherwise it returns true.

  Returns whether or not the supplied keyCode maps to a key that is used for navigation.

  Returns whether or not the supplied keyCode maps to a key that is used for
navigation. This is used for optimizing key input by only passing non-
navigation keys to the type-ahead mechanism. Subclasses should override this
if they change the navigation keys.

Tells if the popup is visible or not.

Returns the area that is reserved for drawing the currently selected item.

unregistered and uninitialized. This method is called as part of the
UI uninstallation process.

Uninstalls the default colors, default font, default renderer, and default editor into the JComboBox.

Removes the focus InputMap and ActionMap.

  Remove the installed listeners from the combo box and its model.

  Remove the installed listeners from the combo box and its model.
The number and types of listeners removed and in this method should be
the same that was added in installListeners

  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
