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 theComponentUI
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:- 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.
- Install a
LayoutManager
on the component if necessary. - Create/add any required sub-components to the component.
- Create/install event listeners on the component.
- Create/install a
PropertyChangeListener
on the component in order to detect and respond to component property changes appropriately. - Install keyboard UI (mnemonics, traversal, etc.) on the component.
- Initialize any appropriate instance data.
- Overrides:
installUI
in classComponentUI
- 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()
-
installDefaults
protected void installDefaults()
Initialize JTable properties, e.g. font, foreground, and background. The font, foreground, and background properties are only set if their current value is either null or a UIResource, other properties are set if the current value is null.- See Also:
installUI(javax.swing.JComponent)
-
installListeners
protected void installListeners()
Attaches listeners to the JTable.
-
installKeyboardActions
protected void installKeyboardActions()
Register all keyboard actions on the JTable.
-
uninstallUI
public void uninstallUI(JComponent c)
Description copied from class:ComponentUI
Reverses configuration which was done on the specified component duringinstallUI
. This method is invoked when thisUIComponent
instance is being removed as the UI delegate for the specified component. This method should undo the configuration performed ininstallUI
, being careful to leave theJComponent
instance in a clean state (no extraneous listeners, look-and-feel-specific property objects, etc.). This should include the following:- Remove any UI-set borders from the component.
- Remove any UI-set layout managers on the component.
- Remove any UI-added sub-components from the component.
- Remove any UI-added event/property listeners from the component.
- Remove any UI-installed keyboard UI from the component.
- Nullify any allocated instance data objects to allow for GC.
- Overrides:
uninstallUI
in classComponentUI
- 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()

getBaseline
public int getBaseline(JComponent c, int width, int height)
Returns the baseline.- Overrides:
getBaseline
in classComponentUI
- Parameters:
c
-JComponent
baseline is being requested forwidth
- the width to get the baseline forheight
- the height to get the baseline for- Returns:
- baseline or a value < 0 indicating there is no reasonable baseline
- Throws:
NullPointerException
- ifc
isnull
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 classComponentUI
- Parameters:
c
-JComponent
to return baseline resize behavior for- Returns:
- an enum indicating how the baseline changes as the component size changes
- Throws:
NullPointerException
- ifc
isnull
- Since:
- 1.6
- See Also:
JComponent.getBaseline(int, int)
-
getMinimumSize
public Dimension getMinimumSize(JComponent c)
Return the minimum size of the table. The minimum height is the row height times the number of rows. The minimum width is the sum of the minimum widths of each column.- Overrides:
getMinimumSize
in classComponentUI
- 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 ornull
- See Also:
JComponent.getMinimumSize()
,LayoutManager.minimumLayoutSize(java.awt.Container)
,ComponentUI.getPreferredSize(javax.swing.JComponent)
-
getPreferredSize
public Dimension getPreferredSize(JComponent c)
Return the preferred size of the table. The preferred height is the row height times the number of rows. The preferred width is the sum of the preferred widths of each column.- Overrides:
getPreferredSize
in classComponentUI
- 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)
-
getMaximumSize
public Dimension getMaximumSize(JComponent c)
Return the maximum size of the table. The maximum height is the row heighttimes the number of rows. The maximum width is the sum of the maximum widths of each column.- Overrides:
getMaximumSize
in classComponentUI
- 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 ornull
- See Also:
JComponent.getMaximumSize()
,LayoutManager2.maximumLayoutSize(java.awt.Container)
-
paint
public void paint(Graphics g, JComponent c)
Paint a representation of thetable
instance that was set in installUI().- Overrides:
paint
in classComponentUI
- Parameters:
g
- theGraphics
context in which to paintc
