使用j**a swing仿window7标准计算器界面

1目标：初始化窗体代码：如下----------------public class view extends jframe{public view(){th**.settitle("计算器");//设置标题th**.setresizable(false);//不可改变大小th**.setlocationrelativeto(**);//居中显示th**.setsize(228, 324);//窗体大小，可以使用faststone capture的屏幕尺量一下win计算器的大小th**.setdefaultcloseoperation(jframe.exit_on_close);//默认关闭操作}public static void main(string[] args) {new view().setv**ible(true);}}2目标：设置菜单代码：如下----------------/*** 创建初始化菜单方法(别忘记在构造函数里调用)*/private void initmenu(){jmb = new jmenubar();//创建菜单条jm_view = new jmenu("查看(v)");//查看菜单jm_view.setmnemonic('v');//设置热键jm_edit = new jmenu("编辑(e)");//编辑菜单jm_edit.setmnemonic('e');jm_help = new jmenu("帮助(h)");//帮助菜单jm_help.setmnemonic('h');jmb.add(jm_view);jmb.add(jm_edit);jmb.add(jm_help);th**.setjmenubar(jmb);//将菜单条加入窗体中}3目标：仿结果显示框代码：如下----------------/*** 创建内容区域初始化方法*/private void initcontent(){//整个窗口区域jpanel jp = new jpanel();jp.setlayout(**);//设置空布局以便绝对定位//显示框区域jpanel jptmp = new jpanel(){//获取背景图片，使用截图工具从win计算器显示框中截取2像素宽度作为背景image bg = new imageicon("imgs/bg.png").getimage();/** * 填充结果显示区域的背景 */@overrideprotected void paintcomponent(graphics g) {super.paintcomponent(g);//x轴平铺满面板for(int i = 0;i<th**.getwidth();i+=bg.getwidth(th**)){g.drawimage(bg, i, 0, th**);//绘制背景图片}}};//设置显示框上方小字体font font_lab = new font("arial", font.bold, 22);jla_input = new jlabel();jla_input.settext("0");//设置字体右对齐jla_input.sethorizontalalignment(jlabel.right);jla_input.setfont(font_lab);//设置显示框中计算结果的字体font_lab = new font("arial", font.bold, 10);jla_show = new jlabel();jla_show.settext("sqrt");//设置字体右对齐jla_show.sethorizontalalignment(jlabel.right);jla_show.setfont(font_lab);//设置显示框区域的位置的大小jptmp.setbounds(14, 15, 190, 50);jptmp.setlayout(new borderlayout());jptmp.add(jla_show,borderlayout.north);jptmp.add(jla_input,borderlayout.center);//设置边框jptmp.setborder(borderfactory.createlineborder(new color(142,156,173)));jp.add(jptmp);th**.setlayout(new borderlayout());th**.add(jp,borderlayout.center);}4目标：绘制其他按钮代码：如下----------------①设置字符枚举类public enum operator{//用于swith判断，待用mc,mr,ms,madd,msubtract,//mc,mr,ms,m+,m-clback,clerror,clclear,opernegation,opersqrt,//<-,ce,c,-/+,开平方n7,n8,n9,operdivide,operper,// /,%,n4,n5,n6,opermultiply,operreciproc,//*,倒数n1,n2,n3,opersubtract,operequ,//-,=n0,operdot,operadd;//+//用于显示public static final string [] labs = new string[]{"mc","mr","ms","m+","m-","←","ce","c","±","√","7","8","9","/","%","4","5","6","*","1/x","1","2","3","-","=","0",".","+"};}②添加按钮jptmp = new jpanel();jptmp.setbounds(14, 72, 196,194);jptmp.setlayout(**);font font_but = new font("arial", font.bold, 10);//创建按钮字体for (int i = 0;
