Constructor Detail

BasicTabbedPaneUI

public BasicTabbedPaneUI()

Method Detail

createUI

public static ComponentUI createUI(JComponent c)

Description copied from class: ComponentUI

Returns an instance of the UI delegate for the specified component. Each subclass must provide its own static createUI method that returns an instance of that UI delegate subclass. If the UI delegate subclass is stateless, it may return an instance that is shared by multiple components. If the UI delegate is stateful, then it should return a new instance per component. The default implementation of this method throws an error, as it should never be invoked.

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

Reloads the mnemonics. This should be invoked when a memonic changes, when the title of a mnemonic changes, or when tabs are added/removed.

resetMnemonics

private void resetMnemonics()

Resets the mnemonics bindings to an empty state.

addMnemonic

private void addMnemonic(int index,
                         int mnemonic)

Adds the specified mnemonic at the specified index.

initMnemonics

private void initMnemonics()

Installs the state needed for mnemonics.

getPreferredSize

public Dimension getPreferredSize(JComponent c)

Description copied from class: ComponentUI

Returns the specified component's preferred size appropriate for the look and feel. If null is returned, the preferred 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 returns null.

Overrides:

getPreferredSize in class ComponentUI

Parameters:

c - the component whose preferred 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.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)

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)

paint

public void paint(Graphics g,
                  JComponent c)

Description copied from class: ComponentUI

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.

Overrides:

paint in class ComponentUI

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)

                            int tabPlacement,
                            int selectedIndex)

Paints the tabs in the tab area. Invoked by paint(). The graphics parameter must be a valid Graphics object. Tab placement may be either: JTabbedPane.TOP, JTabbedPane.BOTTOM, JTabbedPane.LEFT, or JTabbedPane.RIGHT. The selected index must be a valid tabbed pane tab index (0 to tab count - 1, inclusive) or -1 if no tab is currently selected. The handling of invalid parameters is unspecified.

Parameters:

g - the graphics object to use for rendering

tabPlacement - the placement for the tabs within the JTabbedPane

getTabBounds

public Rectangle getTabBounds(JTabbedPane pane,
                              int i)

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

public int getTabRunCount(JTabbedPane pane)

Specified by:

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

getTabAtLocation

private int getTabAtLocation(int x,
                             int y)

Returns the tab index which intersects the specified point in the coordinate space of the component where the tabs are actually rendered, which could be the JTabbedPane (for WRAP_TAB_LAYOUT) or a ScrollableTabPanel (SCROLL_TAB_LAYOUT).

getClosestTab

private int getClosestTab(int x,
                          int y)

Returns the index of the tab closest to the passed in location, note that the returned tab may not contain the location x,y.

translatePointToTabPanel

private Point translatePointToTabPanel(int srcx,
                                       int srcy,
