Ⅰ java中GUI登录界面设计源代码是什么

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.FlowLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;

public class Login {

private JFrame frame = new JFrame("登录");
private Container c = frame.getContentPane();
private JTextField username = new JTextField();
private JPasswordField password = new JPasswordField();
private JButton ok = new JButton("确定");
private JButton cancel = new JButton("取消");
public Login(){
.setSize(300,200);
c.setLayout(new BorderLayout());
initFrame();
frame.setVisible(true);
}

private void initFrame() {

//顶部
JPanel titlePanel = new JPanel();
titlePanel.setLayout(new FlowLayout());
titlePanel.add(new JLabel("系统管理员登录"));
c.add(titlePanel,"North");

//中部表单
JPanel fieldPanel = new JPanel();
fieldPanel.setLayout(null);
JLabel l1 = new JLabel("用户名:");
l1.setBounds(50, 20, 50, 20);
JLabel l2 = new JLabel("密码:");
l2.setBounds(50, 60, 50, 20);
fieldPanel.add(l1);
fieldPanel.add(l2);
username.setBounds(110,20,120,20);
password.setBounds(110,60,120,20);
fieldPanel.add(username);
fieldPanel.add(password);
c.add(fieldPanel,"Center");

//底部按钮
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new FlowLayout());
buttonPanel.add(ok);
buttonPanel.add(cancel);
c.add(buttonPanel,"South");
}

public static void main(String[] args){
new Login();
}

}

Ⅱ java图形界面谁能做出这样的界面只需要一个界面求源代码

用javaFX更简单。拖一拖就可以了，不过需要JavaFX Scene Builder 2.0
用NetBeans IDE创建swing项目也是拖一拖就可以了

Ⅲ 一个简单的登录界面源代码

Ⅳ c语言程序界面源代码

使用一下LINUX系统，就可以感受到C编出来的界面的样子了。
事实上，C可以写出任何形式的界面，只不过过程比较麻烦而已，就像用机器语言也可以写出任何一个程序，只不过工作量将是个天文数字而已。

Ⅳ 哪位大神能把我的C++源代码加个图形界面呀就是Windows那种~重谢

class ConnectCommand : public Command
{
public:
ConnectCommand() {}
bool run(Com *comport) Q_DECL_OVERRIDE;
QString message() Q_DECL_OVERRIDE { return QStringLiteral("建立通讯"); }
};

bool ConnectCommand::run(Com *comport)
{
....
QMetaObject::invokeMethod(model, "updateConnection", Qt::QueuedConnection, Q_ARG(bool, true));
....
}

一个命令模式的程序，命令的执行在一个单独的线程里面（QThread::run()），想执行完毕后更新几个状态，因此用invokeMethod调用相应函数，其中的model是QThread的子类。

Ⅵ Windows界面C语言源代码

你试试吧，我不清楚能不能在BORLAND C里运行。
#include<windows.h>

LRESULT CALLBACK MainWndProc(HWND,UINT,WPARAM,LPARAM);

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
char szClassName[]="MainWClass";
WNDCLASSEX wndclass;
// 用描述主窗口的参数填充WNDCLASSEX结构
wndclass.cbSize=sizeof(wndclass); // 结构的大小
wndclass.style=CS_HREDRAW|CS_VREDRAW|CS_OWNDC; // 指定如果大小改变就重画
wndclass.lpfnWndProc=MainWndProc; // 窗口函数指针
wndclass.cbClsExtra=0; // 没有额外的类内存
wndclass.cbWndExtra=0; // 没有往外的窗口内存
wndclass.hInstance=hInstance; // 实例句柄
wndclass.hIcon=::LoadIcon(NULL,IDI_APPLICATION); // 使用预定义图标
wndclass.hCursor=::LoadCursor(NULL,IDC_ARROW); // 使用预定义的光标
wndclass.hbrBackground=(HBRUSH)::GetStockObject(WHITE_BRUSH); // 使用白色背景画刷
wndclass.lpszMenuName=NULL; // 不指定菜单
wndclass.lpszClassName=szClassName; // 窗口类的名称
wndclass.hIconSm=NULL; // 没有类的小图标
// 注册这个窗口类
::RegisterClassEx(&wndclass);
// 创建主窗口
HWND hwnd=::CreateWindowEx(
0, // dwExStyle,扩展样式
szClassName, // lpClassName,类名
"Window", // lpWindowName,标题
WS_OVERLAPPEDWINDOW, // dwStyle,窗口风格
CW_USEDEFAULT, // X,初始X坐标
CW_USEDEFAULT, // Y,初始Y坐标
CW_USEDEFAULT, // nWidth,宽度
CW_USEDEFAULT, // nHeight,高度
NULL, // hWndParent,父窗口句柄
NULL, // hMenu,菜单句柄
hInstance, // hInstance,程序实例句柄
NULL); // lpParam,用户数据
if(hwnd==NULL)
{
::MessageBox(NULL,"创建窗口出错!","出错",MB_OK);
return -1;
}
// 显示窗口,刷新窗口客户区
::ShowWindow(hwnd,nCmdShow);
::UpdateWindow(hwnd);
// 从消息队列中取出消息，交给窗口函数处理，直到GetMessage返回FALSE，结束消息循环
MSG msg;
while(::GetMessage(&msg,NULL,0,0))
{
// 转换键盘消息
::TranslateMessage(&msg);
// 将消息发送到相应的窗口函数
::DispatchMessage(&msg);
}
// 当GetMessage返回FALSE时程序结束
return msg.wParam;
}

LRESULT CALLBACK MainWndProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
char szText[]="最简单的窗口程序!";
switch(message)
{
case WM_PAINT:
{
HDC hdc;
PAINTSTRUCT ps;
hdc=::BeginPaint(hwnd,&ps);
::EndPaint(hwnd,&ps);
return 0;
}
case WM_DESTROY:
::PostQuitMessage(0);
return 0;
}
return ::DefWindowProc(hwnd,message,wParam,lParam);
}
