Class BasicArrowButton

javax.swing.plaf.basic.BasicArrowButton

All Implemented Interfaces:: ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, SwingConstants

Direct Known Subclasses:: MetalScrollButton

public class BasicArrowButton extends JButton implements SwingConstants

JButton object that draws a scaled Arrow in one of the cardinal directions.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.

Field Details

direction

protected int direction

The direction of the arrow. One of SwingConstants.NORTH, SwingConstants.SOUTH, SwingConstants.EAST or SwingConstants.WEST.

Constructor Details

BasicArrowButton

public BasicArrowButton(int direction, Color background, Color shadow, Color darkShadow, Color highlight)

Creates a BasicArrowButton whose arrow is drawn in the specified direction and with the specified colors.

Parameters:: direction - the direction of the arrow; one of SwingConstants.NORTH, SwingConstants.SOUTH, SwingConstants.EAST or SwingConstants.WEST; background - the background color of the button; shadow - the color of the shadow; darkShadow - the color of the dark shadow; highlight - the color of the highlight
Since:: 1.4

BasicArrowButton

public BasicArrowButton(int direction)

Creates a BasicArrowButton whose arrow is drawn in the specified direction.

Parameters:: direction - the direction of the arrow; one of SwingConstants.NORTH, SwingConstants.SOUTH, SwingConstants.EAST or SwingConstants.WEST

Method Details

getDirection

public int getDirection()

Returns the direction of the arrow.

Returns:: the direction of the arrow

setDirection

public void setDirection(int direction)

Sets the direction of the arrow.

Parameters:: direction - the direction of the arrow; one of of SwingConstants.NORTH, SwingConstants.SOUTH, SwingConstants.EAST or SwingConstants.WEST

getPreferredSize

public Dimension getPreferredSize()

Returns the preferred size of the BasicArrowButton.

Overrides:

getPreferredSize in class JComponent

Returns:

the preferred size

See Also:

getMinimumSize

public Dimension getMinimumSize()

Returns the minimum size of the BasicArrowButton.

Overrides:

getMinimumSize in class JComponent

Returns:

the minimum size

See Also:

getMaximumSize

public Dimension getMaximumSize()

Returns the maximum size of the BasicArrowButton.

Overrides:

getMaximumSize in class JComponent

Returns:

the maximum size

See Also:

isFocusTraversable

public boolean isFocusTraversable()

Returns whether the arrow button should get the focus. BasicArrowButtons are used as a child component of composite components such as JScrollBar and JComboBox. Since the composite component typically gets the focus, this method is overriden to return false.

Overrides:

isFocusTraversable in class Component

Returns:

false

See Also:

paintTriangle

public void paintTriangle(Graphics g, int x, int y, int size, int direction, boolean isEnabled)

Paints a triangle.

Parameters:: g - the Graphics to draw to; x - the x coordinate; y - the y coordinate; size - the size of the triangle to draw; direction - the direction in which to draw the arrow; one of SwingConstants.NORTH, SwingConstants.SOUTH, SwingConstants.EAST or SwingConstants.WEST; isEnabled - whether or not the arrow is drawn enabled
