如何添加性感的开/关滑块？
我想在Java应用程序中添加一个像开关一样的开关。 我需要从Swing Sliders构建它们还是已经有了更接近的东西？

只是一个小例子，也许它会帮助你。
public class Popup extends JFrame { public Popup() { setBounds( 100, 100, 300, 120 ); setDefaultCloseOperation( 3 ); getContentPane().setLayout( new FlowLayout( FlowLayout.LEADING, 10, 10 ) ); getContentPane().add( new JSwitchBox( "on", "off" )); getContentPane().add( new JSwitchBox( "yes", "no" )); getContentPane().add( new JSwitchBox( "true", "false" )); getContentPane().add( new JSwitchBox( "on", "off" )); getContentPane().add( new JSwitchBox( "yes", "no" )); getContentPane().add( new JSwitchBox( "true", "false" )); } public static void main( String[] args ) { SwingUtilities.invokeLater( new Runnable() { @Override public void run() { new Popup().setVisible( true ); } }); } public class JSwitchBox extends AbstractButton{ private Color colorBright = new Color(220,220,220); private Color colorDark = new Color(150,150,150); private Color black = new Color(0,0,0,100); private Color white = new Color(255,255,255,100); private Color light = new Color(220,220,220,100); private Color red = new Color(160,130,130); private Color green = new Color(130,160,130); private Font font = new JLabel().getFont(); private int gap = 5; private int globalWitdh = 0; private final String trueLabel; private final String falseLabel; private Dimension thumbBounds; private Rectangle2D bounds; private int max; public JSwitchBox(String trueLabel, String falseLabel) { this.trueLabel = trueLabel; this.falseLabel = falseLabel; double trueLenth = getFontMetrics( getFont() ).getStringBounds( trueLabel, getGraphics() ).getWidth(); double falseLenght = getFontMetrics( getFont() ).getStringBounds( falseLabel, getGraphics() ).getWidth(); max = (int)Math.max( trueLenth, falseLenght ); gap = Math.max( 5, 5+(int)Math.abs(trueLenth - falseLenght ) ); thumbBounds = new Dimension(max+gap*2,20); globalWitdh = max + thumbBounds.width+gap*2; setModel( new DefaultButtonModel() ); setSelected( false ); addMouseListener( new MouseAdapter() { @Override public void mouseReleased( MouseEvent e ) { if(new Rectangle( getPreferredSize() ).contains( e.getPoint() )) { setSelected( !isSelected() ); } } }); } @Override public Dimension getPreferredSize() { return new Dimension(globalWitdh, thumbBounds.height); } @Override public void setSelected( boolean b ) { if(b){ setText( trueLabel ); setBackground( green ); } else { setBackground( red ); setText( falseLabel ); } super.setSelected( b ); } @Override public void setText( String text ) { super.setText( text ); } @Override public int getHeight() { return getPreferredSize().height; } @Override public int getWidth() { return getPreferredSize().width; } @Override public Font getFont() { return font; } @Override protected void paintComponent( Graphics g ) { g.setColor( getBackground() ); g.fillRoundRect( 1, 1, getWidth()-2 - 1, getHeight()-2 ,2 ,2 ); Graphics2D g2 = (Graphics2D)g; g2.setColor( black ); g2.drawRoundRect( 1, 1, getWidth()-2 - 1, getHeight()-2 - 1, 2,2 ); g2.setColor( white ); g2.drawRoundRect( 1 + 1, 1 + 1, getWidth()-2 - 3, getHeight()-2 - 3, 2,2 ); int x = 0; int lx = 0; if(isSelected()) { lx = thumbBounds.width; } else { x = thumbBounds.width; } int y = 0; int w = thumbBounds.width; int h = thumbBounds.height; g2.setPaint( new GradientPaint(x, (int)(y-0.1*h), colorDark , x, (int)(y+1.2*h), light) ); g2.fillRect( x, y, w, h ); g2.setPaint( new GradientPaint(x, (int)(y+.65*h), light , x, (int)(y+1.3*h), colorDark) ); g2.fillRect( x, (int)(y+.65*h), w, (int)(h-.65*h) ); if (w>14){ int size = 10; g2.setColor( colorBright ); g2.fillRect(x+w/2-size/2,y+h/2-size/2, size, size); g2.setColor( new Color(120,120,120)); g2.fillRect(x+w/2-4,h/2-4, 2, 2); g2.fillRect(x+w/2-1,h/2-4, 2, 2); g2.fillRect(x+w/2+2,h/2-4, 2, 2); g2.setColor( colorDark ); g2.fillRect(x+w/2-4,h/2-2, 2, 6); g2.fillRect(x+w/2-1,h/2-2, 2, 6); g2.fillRect(x+w/2+2,h/2-2, 2, 6); g2.setColor( new Color(170,170,170)); g2.fillRect(x+w/2-4,h/2+2, 2, 2); g2.fillRect(x+w/2-1,h/2+2, 2, 2); g2.fillRect(x+w/2+2,h/2+2, 2, 2); } g2.setColor( black ); g2.drawRoundRect( x, y, w - 1, h - 1, 2,2 ); g2.setColor( white ); g2.drawRoundRect( x + 1, y + 1, w - 3, h - 3, 2,2 ); g2.setColor( black.darker() ); g2.setRenderingHint( RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON ); g2.setFont( getFont() ); g2.drawString( getText(), lx+gap, y+h/2+h/4 ); } } } 使用内置组件JCheckBox。
JCheckBox cb = new JCheckBox(createImageIcon("off-image.gif", "Click To Turn On")); cb.setSelectedIcon(createImageIcon("on-image.gif", "Click To Turn Off"));
也许通过使用JScrollBar，这里只是和不完整的想法，由你决定
import java.awt.*; import java.awt.event.AdjustmentEvent; import java.awt.event.AdjustmentListener; import javax.swing.*; import javax.swing.event.ChangeEvent; import javax.swing.event.ChangeListener; public class Sliders { private JFrame frame; private JPanel main; private JPanel scrollBarPanel = new JPanel(); private JPanel sliderPanel; public Sliders() { frame = new JFrame(); main = new JPanel(new GridLayout(2, 1)); final JScrollBar scrollBar = new JScrollBar(JScrollBar.HORIZONTAL, 0, 100, 0, 200); int height = scrollBar.getPreferredSize().height; scrollBar.setPreferredSize(new Dimension(175, height)); scrollBarPanel.add(scrollBar); main.add(scrollBarPanel); sliderPanel = new JPanel(); final JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 255, 128); slider.setMajorTickSpacing(48); slider.setMinorTickSpacing(16); slider.setPaintTicks(true); sliderPanel.add(slider); main.add(sliderPanel); frame.add(main, BorderLayout.CENTER); scrollBar.addAdjustmentListener(new AdjustmentListener() { @Override public void adjustmentValueChanged(AdjustmentEvent e) { System.out.println("JScrollBar's current value = " + scrollBar.getValue()); } }); slider.addChangeListener(new ChangeListener() { @Override public void stateChanged(ChangeEvent e) { System.out.println("JSlider's current value = " + slider.getValue()); } }); frame.pack(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { Sliders sliders = new Sliders(); } }); } }
