Java实现Swing组件定制Button示例

本文实例讲述了java实现swing组件定制button。分享给大家供大家参考，具体如下：

先来看看运行效果图：

具体代码如下：

package themedemo;
import java.awt.basicstroke;
import java.awt.borderlayout;
import java.awt.color;
import java.awt.graphics2d;
import java.awt.gridlayout;
import java.awt.renderinghints;
import java.util.map;
import javax.swing.borderfactory;
import javax.swing.jbutton;
import javax.swing.jcomponent;
import javax.swing.jframe;
import javax.swing.jpanel;
import javax.swing.painter;
import javax.swing.swingutilities;
import javax.swing.uidefaults;
import javax.swing.uimanager;
import javax.swing.windowconstants;
public class buttonskindemo {
 public static void main(string[] args) {
  swingutilities.invokelater(new runnable() {
   public void run() {
    for (uimanager.lookandfeelinfo laf : uimanager
      .getinstalledlookandfeels()) {
     if ("nimbus".equals(laf.getname())) {
      try {
       uimanager.setlookandfeel(laf.getclassname());
      } catch (exception e) {
       e.printstacktrace();
      }
     }
    }
    for (map.entry<object, object> entry : uimanager
      .getlookandfeeldefaults().entryset()) {
     if ((entry.getkey().tostring()).startswith("button")) {
      system.out.println(entry.getkey() + " = "
        + entry.getvalue());
     }
    }
    jframe frame = new jframe("www.jb51.net - button skining demo");
    frame.setdefaultcloseoperation(windowconstants.exit_on_close);
    frame.getcontentpane().setlayout(new borderlayout());
    jpanel panel = new jpanel(new gridlayout(0, 1, 20, 20));
    panel.setborder(borderfactory.createemptyborder(20, 20, 20, 20));
    panel.setbackground(color.darkgray);
    uidefaults buttondefaults = new uidefaults();
    buttondefaults.put("button.backgroundpainter",
      new painter<jcomponent>() {
       public void paint(graphics2d g, jcomponent c,
         int w, int h) {
        g.setrenderinghint(
          renderinghints.key_antialiasing,
          renderinghints.value_antialias_on);
        g.setstroke(new basicstroke(2f));
        g.setcolor(color.white);
        g.fillroundrect(0, 0, w - 2, h - 2, 8, 8);
        g.setcolor(color.light_gray);
        g.drawroundrect(0, 0, w - 2, h - 2, 8, 8);
       }
      });
    buttondefaults.put("button[pressed].backgroundpainter",
      new painter<jcomponent>() {
       public void paint(graphics2d g, jcomponent c,
         int w, int h) {
        g.setrenderinghint(
          renderinghints.key_antialiasing,
          renderinghints.value_antialias_on);
        g.setstroke(new basicstroke(2f));
        g.setcolor(color.light_gray);
        g.fillroundrect(0, 0, w - 2, h - 2, 8, 8);
       }
      });
    jbutton button = new jbutton("mybutton");
    panel.add(button);
    button.putclientproperty("nimbus.overrides", buttondefaults);
    button.putclientproperty("nimbus.overrides.inheritdefaults",
      false);
    // add a normal themed slider for comparison
    jbutton normalbutton = new jbutton("normalbutton");
    panel.add(normalbutton);
    frame.getcontentpane().add(panel, borderlayout.center);
    frame.pack();
    frame.setlocationrelativeto(null);
    frame.setvisible(true);
   }
  });
 }
}
