  • 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

     1 文本编辑框的样式
        1.1 单行文本编辑框 - 默认样式
        1.2 多行文本编辑框 - ES_MULTILINE
        1.3 password文本编辑框 - ES_PASSWORD
      2 文本编辑框的使用
        2.1 创建 
           窗体类名称EDIT.
        2.2 Notify消息
           EN_CHANGE 当编辑框内容发生变化时,会通知父窗体
        2.3 EDIT窗体消息
           EM_SETSEL 选择消息 WPARAM是起始字符位置
               LPARAM是终止字符位置
           窗体消息: WM_COPY, WM_PASET,WM_CUT等消息
             WM_SETTEXT, WM_GETTEXT, WM_GETTEXTLEN
             SetWindowText
