本文实例讲述了java swing实现的定制textfield功能。分享给大家供大家参考，具体如下：

先来看看运行效果：

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.jcomponent;

									import javax.swing.jframe;

									import javax.swing.jpanel;

									import javax.swing.jtextfield;

									import javax.swing.painter;

									import javax.swing.swingutilities;

									import javax.swing.uidefaults;

									import javax.swing.uimanager;

									import javax.swing.windowconstants;

									public class textfieldskindemo {

									  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("textfield")) {

									            system.out.println(entry.getkey() + " = "

									                + entry.getvalue());

									          }

									        }

									        jframe frame = new jframe("www.zzvips.com - textfield 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 textfielddefaults = new uidefaults();

									        textfielddefaults.put("textfield.contentmargins", new insets(6,

									            6, 6, 6));

									        textfielddefaults.put("textfield[selected].textforeground",

									            color.white);

									        textfielddefaults.put("textfield.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);

									              }

									            });

									        textfielddefaults.put("textfield.borderpainter",

									            new painter<jcomponent>() {

									              public void paint(graphics2d g, jcomponent c,

									                g.setstroke(new basicstroke(2f));

									                g.setcolor(color.light_gray);

									                g.drawroundrect(0, 0, w - 2, h - 2, 8, 8);

									              }

									            });

									        jtextfield textfield = new jtextfield(15);

									        panel.add(textfield);

									        textfield.putclientproperty("nimbus.overrides",

									            textfielddefaults);

									        textfield.putclientproperty("nimbus.overrides.inheritdefaults",

									            false);

									        // add a normal themed slider for comparison

									        jtextfield normaltextfield = new jtextfield(15);

									        panel.add(normaltextfield);

									        frame.getcontentpane().add(panel, borderlayout.center);

									        frame.pack();

									        frame.setlocationrelativeto(null);

									        frame.setvisible(true);

									      }
