Constructor Detail

### BasicTabbedPaneUI

    public BasicTabbedPaneUI()

Method Detail

### createUI

    public static ComponentUI createUI(JComponent c)

### installUI

    public void installUI(JComponent c)

  Description copied from class: `ComponentUI`
  Configures the specified component appropriate for the look and feel. This method is invoked when the `ComponentUI` instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:
  1. Install any default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
  2. Install a `LayoutManager` on the component if necessary.
  3. Create/add any required sub-components to the component.
  4. Create/install event listeners on the component.
  5. Create/install a `PropertyChangeListener` on the component in order to detect and respond to component property changes appropriately.
  6. Install keyboard UI (mnemonics, traversal, etc.) on the component.
  7. Initialize any appropriate instance data.

  Overrides:
    `installUI` in class `ComponentUI`
  Parameters:
    `c` - the component where this UI delegate is being installed
  See Also:
    `ComponentUI.uninstallUI(javax.swing.JComponent)`, `JComponent.setUI(javax.swing.plaf.ComponentUI)`, `JComponent.updateUI()`

### uninstallUI

    public void uninstallUI(JComponent c)

  Description copied from class: `ComponentUI`
  Reverses configuration which was done on the specified component during `installUI`. This method is invoked when this `UIComponent` instance is being removed as the UI delegate for the specified component. This method should undo the configuration performed in `installUI`, being careful to leave the `JComponent` instance in a clean state (no extraneous listeners, look-and-feel-specific property objects, etc.). This should include the following:
  1. Remove any UI-set borders from the component.
  2. Remove any UI-set layout managers on the component.
  3. Remove any UI-added sub-components from the component.
  4. Remove any UI-added event/property listeners from the component.
  5. Remove any UI-installed keyboard UI from the component.
  6. Nullify any allocated instance data objects to allow for GC.

  Overrides:
    `uninstallUI` in class `ComponentUI`
  Parameters:
    `c` - the component from which this UI delegate is being removed; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
  See Also:
    `ComponentUI.installUI(javax.swing.JComponent)`, `JComponent.updateUI()`

### createLayoutManager

### getMinimumSize

    public Dimension getMinimumSize(JComponent c)

  Description copied from class: `ComponentUI`
  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.

  Overrides:
    `getMinimumSize` in class `ComponentUI`
  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
  Returns:
    a `Dimension` object or `null`
  See Also:
    `JComponent.getMinimumSize()`, `LayoutManager.minimumLayoutSize(java.awt.Container)`, `ComponentUI.getPreferredSize(javax.swing.JComponent)`

### getMaximumSize

    public Dimension getMaximumSize(JComponent c)

  Description copied from class: `ComponentUI`
  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.

  Overrides:
    `getMaximumSize` in class `ComponentUI`
  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
  Returns:
    a `Dimension` object or `null`
  See Also:
    `JComponent.getMaximumSize()`, `LayoutManager2.maximumLayoutSize(java.awt.Container)`

### getBaseline

    public int getBaseline(JComponent c,
                           int width,

  Returns the baseline.

  Overrides:
    `getBaseline` in class `ComponentUI`
  Parameters:
    `c` - `JComponent` baseline is being requested for
    `width` - the width to get the baseline for
    `height` - the height to get the baseline for
  Returns:
    baseline or a value < 0 indicating there is no reasonable baseline
  Throws:
    `NullPointerException` - if `c` is `null`
    `IllegalArgumentException` - if width or height is < 0
  Since:
    1.6
  See Also:
    `JComponent.getBaseline(int, int)`

### getBaselineResizeBehavior

  Parameters:
    `c` - `JComponent` to return baseline resize behavior for

    an enum indicating how the baseline changes as the component size changes
  Throws:
    `NullPointerException` - if `c` is `null`

  Parameters:
    `tab` - index of tab to get baseline for
  Returns:
    baseline or a value < 0 indicating there is no reasonable baseline
  Throws:
    `IndexOutOfBoundsException` - if index is out of range (index < 0 || index >= tab count)
  Since:
    1.6

### getBaselineOffset

    protected int getBaselineOffset()

  Returns the amount the baseline is offset by. This is typically the same as `getTabLabelShiftY`.

  Returns:

### getTabBounds

    public Rectangle getTabBounds(JTabbedPane pane,

  Returns the bounds of the specified tab index. The bounds are with respect to the JTabbedPane's coordinate space.

  Specified by:
    `getTabBounds` in class `TabbedPaneUI`

### getTabRunCount

### getTabBounds

    protected Rectangle getTabBounds(int tabIndex,
                                     Rectangle dest)

  Returns the bounds of the specified tab in the coordinate space of the JTabbedPane component. This is required because the tab rects are by default defined in the coordinate space of the component where they are rendered, which could be the JTabbedPane (for WRAP_TAB_LAYOUT) or a ScrollableTabPanel (SCROLL_TAB_LAYOUT). This method should be used whenever the tab rectangle must be relative to the JTabbedPane itself and the result should be placed in a designated Rectangle object (rather than instantiating and returning a new Rectangle each time). The tab index parameter must be a valid tabbed pane tab index (0 to tab count - 1, inclusive). The destination rectangle parameter must be a valid `Rectangle` instance. The handling of invalid parameters is unspecified.

  Parameters:
    `tabIndex` - the index of the tab
    `dest` - the rectangle where the result should be placed
  Returns:
    the resulting rectangle

    1.4
