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 JavaBeansTM has been added to the
java.beans
package. Please seeXMLEncoder

paint
public void paint(Graphics g)
Description copied from class:JComponent
Invoked by Swing to draw components. Applications should not invokepaint
directly, but should instead use therepaint
method to schedule the component for redrawing.This method actually delegates the work of painting to three protected methods:
paintComponent
,paintBorder
, andpaintChildren
. 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'spaint
method should just overridepaintComponent
.- Overrides:
paint
in classJComponent
- Parameters:
g
- theGraphics
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 theBasicArrowButton
.- Overrides:
getPreferredSize
in classJComponent
- Returns:
- the preferred size
- See Also:
JComponent.setPreferredSize(java.awt.Dimension)
,ComponentUI
-
getMinimumSize
public Dimension getMinimumSize()
Returns the minimum size of theBasicArrowButton
.- Overrides:
getMinimumSize
in classJComponent
- Returns:
- the minimum size
- See Also:
JComponent.setMinimumSize(java.awt.Dimension)
,ComponentUI
-
getMaximumSize
public Dimension getMaximumSize()
Returns the maximum size of theBasicArrowButton
.- Overrides:
getMaximumSize
in classJComponent
- 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.BasicArrowButton
s are used as a child component of composite components such asJScrollBar
andJComboBox
. Since the composite component typically gets the focus, this method is overriden to returnfalse
.- Overrides:
isFocusTraversable
in classComponent
- 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
- theGraphics
to draw tox
- the x coordinatey
- the y coordinatesize
- the size of the triangle to drawdirection
- the direction in which to draw the arrow; one ofSwingConstants.NORTH
,SwingConstants.SOUTH
,SwingConstants.EAST
orSwingConstants.WEST
isEnabled
- whether or not the arrow is drawn enabled
