对话框

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

5 无模式对话框的使用

 5.1 添加对话框资源

 5.2 定义窗口处理函数

   BOOL CALLBACK DialogProc(

HWND hwndDlg,  // handle to dialog box

UINT uMsg,     // message

WPARAM wParam, // first message parameter

LPARAM lParam ); // second message parameter

5.3 创建对话框

   HWND CreateDialog(

  HINSTANCE hInstance,//利用程序实例句柄

  LPCTSTR lpTemplate,//对话框的资源ID

  HWND hWndParent,//父窗口

  DLGPROC lpDialogFunc );//对话框的窗口处理函数

 返回值是创建好的对话框的窗口句柄。

5.4 显示对话框

   ShowWindow

5.5 关闭对话框

   EndDialog


点击查找的时候, 无模式对话框出来。

// WinModelessDlg.cpp : Defines the entry point for the application. // #include "stdafx.h" #include "resource.h" HINSTANCE g_hInst = NULL; BOOL CALLBACK FindDlgProc( HWND hWnd, UINT nMsg, WPARAM wParam, LPARAM lParam ) { switch( nMsg ) { case WM_CREATE: MessageBox( NULL, "WM_CREATE", "WinDlg", MB_OK ); break; case WM_INITDIALOG: MessageBox( NULL, "WM_INITDIALOG", "WinDlg", MB_OK ); break; case WM_SYSCOMMAND: { switch( wParam ) { case SC_CLOSE: EndDialog( hWnd, 0 ); break; } } break; } return 0; } void Find( HWND hWnd ) { //创建对话框 HWND hDlg = CreateDialog( g_hInst, MAKEINTRESOURCE(IDD_FIND), hWnd, FindDlgProc ); //显示对话框 ShowWindow( hDlg, SW_SHOW ); } void OnCommand( HWND hWnd, UINT nMsg, WPARAM wParam, LPARAM lParam ) { int nCmdID = LOWORD( wParam ); switch( nCmdID ) { case ID_EXIT: PostQuitMessage( 0 ); break; case ID_FIND: Find( hWnd ); break; } } LRESULT CALLBACK WndProc( HWND hWnd, UINT nMsg, WPARAM wParam, LPARAM lParam ) { switch( nMsg ) { case WM_COMMAND: OnCommand( hWnd, nMsg, wParam, lParam ); break; case WM_DESTROY: PostQuitMessage( 0 ); return 0; } return DefWindowProc( hWnd, nMsg, wParam, lParam ); } BOOL RegisterWnd( LPSTR pszClassName ) { WNDCLASSEX wce = { 0 }; wce.cbSize = sizeof( wce ); wce.cbClsExtra = 0; wce.cbWndExtra = 0; wce.hbrBackground = HBRUSH(COLOR_WINDOW); wce.hCursor = NULL; wce.hIcon = NULL; wce.hIconSm = NULL; wce.hInstance = g_hInst; wce.lpfnWndProc = WndProc; wce.lpszClassName = pszClassName; wce.lpszMenuName = NULL; wce.style = CS_HREDRAW|CS_VREDRAW; ATOM nAtom = RegisterClassEx( &wce ); if( 0 == nAtom ) { return FALSE; } return TRUE; } HWND CreateWnd( LPSTR pszClassName ) { HMENU hMenu = LoadMenu( g_hInst, MAKEINTRESOURCE(IDR_MAIN) ); HWND hWnd = CreateWindowEx( 0, pszClassName, "MyWnd", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, hMenu, g_hInst, NULL ); return hWnd; } void DisplayWnd( HWND hWnd ) { ShowWindow( hWnd, SW_SHOW ); UpdateWindow( hWnd ); } void Message( ) { MSG msg = { 0 }; while( GetMessage( &msg, NULL, 0, 0 ) ) { TranslateMessage( &msg ); DispatchMessage( &msg ); } } int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { g_hInst = hInstance; RegisterWnd( "MYWND" ); HWND hWnd = CreateWnd( "MYWND" ); DisplayWnd( hWnd ); Message( ); return 0; }

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

   程序履行方式:

有模式对话框会阻塞,制止其他窗口的输入

无模式对话框会让主程序,不影响其它窗口的输入

 

6 对话框中的消息        

 

WM_INITDIALOG消息,用处类似于WM_CREATE消息

可以在对话框创建完成后,进行数据初始化.

它与WM_CREATE不同的地方是,WM_INITDIALOG消息

会在对话框资源模板上的所有子控件(按钮等)

创建完成后,再发送给对话框窗口.

  wParam - 当前接受输入焦点子控件窗口句柄

  lParam - 创建时附带的参数

 

7 对话框和普通窗口的对照

7.1 创建方式

  普通窗口: CreateWindow/Ex

  对话框: DialogBox/CreateDialog

7.2 消息

  普通窗口: 会收到WM_CREATE

  对话框:   WM_INITDIALOG

7.3 关闭方式:

  普通窗口: DestoryWindow

  对话框: EndDialog

子控件

 

  1 子控件

  

    1.1 控件的类型

    Windows系统定义的窗口类型,可以提供

    相应的功能.包括按钮、文本编辑框、静态框等.

    

    1.2 控件的创建

    都可使用CreateWindow/CreateWindowEx

    创建,并获得到控件HWND。创建时每一个子控件

    都要有相应的ID号,ID号要求不重复。

    

    1.3 控件的消息

    子控件和父窗口(1般窗口或对话框)的交互

    都是通过消息完成。如果子窗口状态产生变化,

    子窗口会向父窗口发送相应的消息。

    1般父窗口会使用SendMessage函数向子窗口

    发送消息。

    父窗口响应子窗口发送的消息1般是在

    WM_COMMAND进行处理。

静态框

 

  1 静态框创建

    窗口类的名称 - STATIC, 用于窗口上

    显示文字等, 如果使用SS_ICON/SS_BITMAP

    风格可以显示ICONBITMAP

    

    文本静态框 - 创建时使用SS_SIMPLE便可

    ICON静态框 -创建时需要使用SS_ICON,并且

       将静态框的窗口名称设置成对应ICON的资源

       ID,例如"#101".

    

  2 静态框的命令相应

    2.1 静态框要添加SS_NOTIFY风格

    2.2 WM_COMMAND进行处理

       WPARAM - HIWORD 命令ID

                LOWORD 静态框的窗口ID

       LPARAM - 静态框的窗口句柄.  

    

  3 静态框的消息

    调用SendMessage函数,Static控件发送消息

    例如: STM_SETICON消息修改控件显示图标

      SendMessage( hStatic, STM_SETICON,

(WPARAM)hIcon, 0 );

其他:

  GetDlgItem 从窗口中获得指定ID的子控件的

    窗口句柄

// WinStatic.cpp : Defines the entry point for the application. // #include "stdafx.h" #include "resource.h" HINSTANCE g_hInst = NULL; void OnCreate( HWND hWnd, UINT nMsg, WPARAM wParam, LPARAM lParam ) { CreateWindow( "STATIC", "hello Static", WS_CHILD|WS_VISIBLE|SS_SUNKEN|SS_SIMPLE|SS_NOTIFY, 50, 50, 100, 100, hWnd, (HMENU)1001, g_hInst, NULL ); CreateWindow( "STATIC", "#101", WS_CHILD|WS_VISIBLE|SS_SUNKEN|SS_ICON|SS_NOTIFY, 200, 50, 100, 100, hWnd, (HMENU)1002, g_hInst, NULL ); } void OnCommand( HWND hWnd, UINT nMsg, WPARAM wParam, LPARAM lParam ) { int nCmdID = HIWORD( wParam ); int nCtrlID = LOWORD( wParam ); switch( nCtrlID ) { case 1001: case 1002: { switch( nCmdID ) { case STN_CLICKED: MessageBox( NULL, "Hello Static", "WinStatic", MB_OK ); break; } } break; } } LRESULT CALLBACK WndProc( HWND hWnd, UINT nMsg, WPARAM wParam, LPARAM lParam ) { switch( nMsg ) { case WM_CREATE: OnCreate( hWnd, nMsg, wParam, lParam ); break; case WM_COMMAND: OnCommand( hWnd, nMsg, wParam, lParam ); break; case WM_DESTROY: PostQuitMessage( 0 ); return 0; } return DefWindowProc( hWnd, nMsg, wParam, lParam ); } BOOL RegisterWnd( LPSTR pszClassName ) { WNDCLASSEX wce = { 0 }; wce.cbSize = sizeof( wce ); wce.cbClsExtra = 0; wce.cbWndExtra = 0; wce.hbrBackground = HBRUSH(COLOR_WINDOW); wce.hCursor = NULL; wce.hIcon = NULL; wce.hIconSm = NULL; wce.hInstance = g_hInst; wce.lpfnWndProc = WndProc; wce.lpszClassName = pszClassName; wce.lpszMenuName = NULL; wce.style = CS_HREDRAW|CS_VREDRAW; ATOM nAtom = RegisterClassEx( &wce ); if( 0 == nAtom ) { return FALSE; } return TRUE; } HWND CreateWnd( LPSTR pszClassName ) { HWND hWnd = CreateWindowEx( 0, pszClassName, "MyWnd", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, g_hInst, NULL ); return hWnd; } void DisplayWnd( HWND hWnd ) { ShowWindow( hWnd, SW_SHOW ); UpdateWindow( hWnd ); } void Message( ) { MSG msg = { 0 }; while( GetMessage( &msg, NULL, 0, 0 ) ) { TranslateMessage( &msg ); DispatchMessage( &msg ); } } int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { g_hInst = hInstance; RegisterWnd( "MYWND" ); HWND hWnd = CreateWnd( "MYWND" ); DisplayWnd( hWnd ); Message( ); return 0; }

按钮

1 按钮的分类

 根据创建按钮时使用的风格:

 1.1 下压式按钮 PUSH BUTTON

正常下压式按钮 BS_PUSHBUTTON

3态下压按钮 BS_3STATE/BS_AUTO3STATE

 1.2 分组按钮 Group Button

按钮样式:BS_GROUPBOX

 1.3 多选按钮   Check Box

按钮样式:BS_CHECKBOX/BS_AUTOCHECKBOX

 1.4 单选按钮   Radio Box

按钮样式:BS_RADIOBUTTON/

 BS_AUTORADIOBUTTON

2 下压式按钮的使用
 2.1 创建按钮
创建时使用BUTTON
 2.2 命令消息
BN_CLICKED消息: 当点击按钮通过
 WM_COMMAND消息通知父窗口
 2.3 通知消息 
SendMessage

3 分组按钮
 3.1 创建分组按钮
 3.2 经常使用于对窗口内控件划分区域,增加
界面的友好性

4 多选按钮 CheckBox
 4.1 创建使用 BS_CHECKBOX/BS_AUTOCHECKBOX
   BS_AUTOCHECKBOX 选择状态系统自动保护
   BS_CHECKBOX 选择状态需要自己保护
 4.2 命令响应
   BN_CLICKED 通过WM_COMMAND消息
 4.3 通知消息
   BM_GETCHECK 获得当前按钮被选择的状态
   BM_SETCHECK 设置当前按钮被选择的状态
 wParam 用于设置状态标示
   状态: BST_CHECKED 或 BST_UNCHECKED
   
5 单选按钮 RadioBox
 5.1 创建使用 BS_RADIOBUTTON/BS_AUTORADIOBUTTON
   BS_AUTORADIOBUTTON 选择状态系统自动保护
   BS_RADIOBUTTON 选择状态需要自己保护
   注意:
   RadionBox分组 - 使用WS_GROUP样式,可以将
   RadionBox分成多个组.
 A CreateWindow (  ,,,WS_GROUP );
 B CreateWindow...
 C CreateWindow (  ,,,WS_GROUP );
 D CreaetWindow...
 A和B是1组, C和D是1组
 5.2 命令响应
   BN_CLICKED 通过WM_COMMAND消息
 5.3 通知消息
   与CheckBox类似
