createUI

public static ComponentUI createUI(JComponent c)

Returns a new instance of BasicTableUI.

Parameters:

c - a component

Returns:

a new instance of BasicTableUI

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.

installListeners

protected void installListeners()

Attaches listeners to the JTable.

installKeyboardActions

protected void installKeyboardActions()

Register all keyboard actions on the JTable.

uninstallDefaults

protected void uninstallDefaults()

Uninstalls default properties.

uninstallListeners

protected void uninstallListeners()

Unregisters listeners.

uninstallKeyboardActions

protected void uninstallKeyboardActions()

Unregisters keyboard actions.

getBaseline

public int getBaseline(JComponent c,
                       int width,
                       int height)

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:

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 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)

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 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

Returns:

a Dimension object containing given component's preferred size appropriate for the look and feel

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 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)

Paint a representation of the table instance that was set in installUI().

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
