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 appropriately 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 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()

Parameters:
index - Index of the tab the mouse is over.
Since:
1.5

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

public Component.BaselineResizeBehavior getBaselineResizeBehavior(JComponent c)
Returns an enum indicating how the baseline of the component changes as the size changes.

Overrides:
getBaselineResizeBehavior in class ComponentUI
Parameters:
c - JComponent to return baseline resize behavior for
Returns:
an enum indicating how the baseline changes as the component size changes
Throws:
NullPointerException - if c is null
Since:

getBaseline

protected int getBaseline(int tab)
Returns the baseline for the specified tab.

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:
amount to offset the baseline by
Since:
1.6

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

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:
getTabRunCount in class TabbedPaneUI

tabForCoordinate

public int tabForCoordinate(JTabbedPane pane,
                            int x,
                            int y)
Returns the tab index which intersects the specified point in the JTabbedPane's coordinate space.

Specified by:
tabForCoordinate in class TabbedPaneUI

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
