走进windows编程的世界-----对话框、文本框、button

1 对话框的分类
  2 对话框的基本使用方式
  3 对话框资源
  4 有模式对话框的使用

      

int DialogBox(
 HINSTANCE hInstance,
 LPCTSTR lpTemplate,
 HWND hWndParent,
 DLGPROC lpDialogFunc
);


  5 无模式对话框的使用
    5.1 加入对话框资源
    5.2 定义窗体处理函数

复制代码
 BOOL CALLBACK DialogProc(
  HWND hwndDlg,  // handle to dialog box
    UINT uMsg,     // message
    WPARAM wParam, // first message parameter
    LPARAM lParam     ); // second message parameter
复制代码

    5.3 创建对话框

复制代码
 HWND CreateDialog(
  HINSTANCE hInstance,//应用程序实例句柄
  LPCTSTR lpTemplate,//对话框的资源ID
  HWND hWndParent,//父窗体
  DLGPROC lpDialogFunc );//对话框的窗体处理函数
复制代码

     返回值是创建好的对话框的窗体句柄。


    5.4 显示对话框
       ShowWindow
    5.5 关闭对话框
       EndDialog
    5.6 与有模式对话框对照
       创建函数: 有模式对话框 DialogBox
                 无模式对话框 CreateDialog
       程序运行方式: 
        有模式对话框会堵塞,禁止其它窗体的输入
        无模式对话框会让主程序,不影响其它窗体的输入

  6 对话框中的消息        
  
    WM_INITDIALOG消息,用途相似于WM_CREATE消息
    能够在对话框创建完毕后,进行数据初始化.
    它与WM_CREATE不同之处是,WM_INITDIALOG消息
    会在对话框资源模板上的全部子控件(button等)
    创建完毕后,再发送给对话框窗体. 
      wParam - 当前接受输入焦点子控件窗体句柄
      lParam - 创建时附带的參数

  7 对话框和普通窗体的对照
    7.1 创建方式 
      普通窗体: CreateWindow/Ex
      对话框: DialogBox/CreateDialog
    7.2 消息
      普通窗体: 会收到WM_CREATE
      对话框:   WM_INITDIALOG
    7.3 关闭方式:
      普通窗体: DestoryWindow等
      对话框: EndDialog

1 静态框创建
    窗体类的名称 - STATIC, 用于窗体上
    显示文字等, 假设使用SS_ICON/SS_BITMAP
    风格能够显示ICON和BITMAP
    
    文本静态框 - 创建时使用SS_SIMPLE就可以
    ICON静态框 - 创建时须要使用SS_ICON, 而且将静态框的窗体名称设置成相应ICON的资源ID号,比如"#101".
    
  2 静态框的命令相应
    2.1 静态框要加入SS_NOTIFY风格
    2.2 WM_COMMAND进行处理
       WPARAM - HIWORD 命令ID
                LOWORD 静态框的窗体ID
       LPARAM - 静态框的窗体句柄.  
    
  3 静态框的消息
    调用SendMessage函数,向Static控件发送消息
    比如: STM_SETICON消息改动控件显示图标
      SendMessage( hStatic, STM_SETICON,
    (WPARAM)hIcon, 0 );
  其它:

   GetDlgItem 从窗体中获取指定ID的子控件的窗体句柄

 button

   1 button的分类
     依据创建button时使用的风格:
     1.1 下压式button PUSH BUTTON 
        正常下压式button BS_PUSHBUTTON 
        三态下压button BS_3STATE/BS_AUTO3STATE
     1.2 分组button Group Button
        button样式:BS_GROUPBOX
     1.3 多选button   Check Box 
        button样式:BS_CHECKBOX/BS_AUTOCHECKBOX
     1.4 单选button   Radio Box
        button样式:BS_RADIOBUTTON/
                 BS_AUTORADIOBUTTON
                 
   2 下压式button的使用
     2.1 创建button
        创建时使用BUTTON
     2.2 命令消息
        BN_CLICKED消息: 当点击button通过WM_COMMAND消息通知父窗体
     2.3 通知消息 
        SendMessage
        
   3 分组button
     3.1 创建分组button
     3.2 经常使用于对窗体内控件划分区域,添加界面的友好性
        
   4 多选button CheckBox
     4.1 创建使用 BS_CHECKBOX/BS_AUTOCHECKBOX
       BS_AUTOCHECKBOX 选择状态系统自己主动维护
       BS_CHECKBOX 选择状态须要自己维护
     4.2 命令响应
       BN_CLICKED 通过WM_COMMAND消息
     4.3 通知消息
       BM_GETCHECK 获取当前button被选择的状态
       BM_SETCHECK 设置当前button被选择的状态
          wParam 用于设置状态标示
       状态: BST_CHECKED 或 BST_UNCHECKED
       
   5 单选button RadioBox
     5.1 创建使用 BS_RADIOBUTTON/BS_AUTORADIOBUTTON
       BS_AUTORADIOBUTTON 选择状态系统自己主动维护
       BS_RADIOBUTTON 选择状态须要自己维护
       注意:
       RadionBox分组 - 使用WS_GROUP样式,能够将
       RadionBox分成多个组.
          A CreateWindow (  ,,,WS_GROUP );
          B CreateWindow...
          C CreateWindow (  ,,,WS_GROUP );
          D CreaetWindow...
          A和B是一组, C和D是一组
     5.2 命令响应
       BN_CLICKED 通过WM_COMMAND消息
     5.3 通知消息
       与CheckBox相似
