Field Detail

direction

protected int direction

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

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

getDirection

public int getDirection()

Returns the direction of the arrow.

Parameters:

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

setDirection

public void setDirection(int dir)

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

paint

public void paint(Graphics g)

Description copied from class: JComponent

Invoked by Swing to draw components. Applications should not invoke paint directly, but should instead use the repaint method to schedule the component for redrawing.

This method actually delegates the work of painting to three protected methods: paintComponent, paintBorder, and paintChildren. They're called in the order listed to ensure that children appear on top of component itself. Generally speaking, the component and its children should not paint in the insets area allocated to the border. Subclasses can just override this method, as always. A subclass that just wants to specialize the UI (look and feel) delegate's paint method should just override paintComponent.

Overrides:

paint in class JComponent

Parameters:

g - the Graphics context in which to paint

See Also:

JComponent.paintComponent(java.awt.Graphics), JComponent.paintBorder(java.awt.Graphics), JComponent.paintChildren(java.awt.Graphics), JComponent.getComponentGraphics(java.awt.Graphics), JComponent.repaint(long, int, int, int, int)

getPreferredSize

public Dimension getPreferredSize()

Returns the preferred size of the BasicArrowButton.

Overrides:

getPreferredSize in class JComponent

Returns:

the preferred size

See Also:

JComponent.setPreferredSize(java.awt.Dimension), ComponentUI

getMinimumSize

public Dimension getMinimumSize()

Returns the minimum size of the BasicArrowButton.

Overrides:

getMinimumSize in class JComponent

Returns:

the minimum size

See Also:

JComponent.setMinimumSize(java.awt.Dimension), ComponentUI

getMaximumSize

public Dimension getMaximumSize()

Returns the maximum size of the BasicArrowButton.

Overrides:

getMaximumSize in class JComponent

Returns:

the maximum size

See Also:

JComponent.setMaximumSize(java.awt.Dimension), ComponentUI

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:

Component.setFocusable(boolean)

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
