Question

我正在使用C和Win32 api创建GUI应用程序。我想知道如何将主窗口的默认字体更改为thaoma。我是从.NET背景出来的。在.NET中，如果我们更改父控件的字体，那么子控件会自动继承该字体.... 是否有相似之处或我们需要手动设置每个控件的字体.....

考虑以下代码......

#include <windows.h>

#define ID_EDIT 1
#define ID_BUTTON 2

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{

  static HWND hwndEdit;
  static HWND hwndButton;
  static int len;
  static TCHAR text[30];


  switch(msg)
  {
    case WM_CREATE:
    hwndEdit = CreateWindow(TEXT("Edit"), NULL, WS_CHILD | WS_VISIBLE | WS_BORDER,
                50, 50, 150, 20, hwnd, (HMENU) ID_EDIT,
                NULL, NULL);

    hwndButton = CreateWindow(
        TEXT("button"), TEXT("Set Title"),       
        WS_VISIBLE | WS_CHILD,  
        50, 100, 80, 25,        
        hwnd, (HMENU) ID_BUTTON, NULL, NULL);      

    break;


    case WM_DESTROY:
        PostQuitMessage(0);
    break;
  }
  return DefWindowProc(hwnd, msg, wParam, lParam);
}

int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance,
            LPSTR lpCmdLine, int nCmdShow )
{
  MSG  msg ;    
  WNDCLASS wc = {0};
  wc.lpszClassName = TEXT( "Edit Control" );
  wc.hInstance     = hInstance ;
  wc.hbrBackground = GetSysColorBrush(COLOR_3DFACE);
  wc.lpfnWndProc   = WndProc ;
  wc.hCursor       = LoadCursor(0,IDC_ARROW);


  RegisterClass(&wc);
  CreateWindow( wc.lpszClassName, TEXT("Edit control"),
                WS_OVERLAPPEDWINDOW | WS_VISIBLE,
                220, 220, 280, 200, 0, 0, hInstance, 0);  

  while( GetMessage(&msg, NULL, 0, 0)) {
    TranslateMessage(&msg);
    DispatchMessage(&msg);
  }
  return (int) msg.wParam;
}

如何更改上述程序中按钮，文本框的字体..

请在这里帮助我.......并告诉我在win32 api编码时遵循的一般过程....

提前谢谢..

可能你尝试创建一个基于对话框的GUI应用程序，它看起来有点像.NET中的基于表单的应用程序。您可以为表单定义字体，并且其所有子控件都继承该字体。每个对话框都存在密切的情况。

如何创建一个关于Win32 API的对话框，您可以在此处阅读：http://msdn.microsoft.com/en-us/library/ms644996%28VS.85%29.aspx。与形式创建相比，对话编程的主要区别在于您应该使用资源编辑器（例如Visual Studio或Windows SDK内部）来设计对话框。结果将保存在RC文件中（尚未编译的资源文件）。结果如下：

IDD_ABOUTBOX DIALOGEX 0, 0, 205, 98
STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_CAPTION | 
    WS_SYSMENU
CAPTION "About"
FONT 8, "MS Shell Dlg 2", 400, 0, 0x1
BEGIN
    DEFPUSHBUTTON   "OK",IDOK,77,77,50,14
    LTEXT           "Trust to User (T2U) v1.0\n\n(c) Copyright 2003, 2004",
                    IDC_STATIC,72,32,120,32
    ICON            IDR_MAINFRAME,IDC_STATIC,25,27,20,20
    GROUPBOX        "",IDC_STATIC,7,3,191,69
    LTEXT           "OK soft  GmbH",IDC_OK_SOFT_GMBH,72,16,120,8
END

您可以在同一个RC文件中保存更多作为不同语言的资源：

IDD_ABOUTBOX DIALOGEX 0, 0, 205, 98
STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_CAPTION | 
    WS_SYSMENU
CAPTION "バージョンの情報"
FONT 8, "MS Shell Dlg 2", 400, 0, 0x1
BEGIN
    DEFPUSHBUTTON   "OK",IDOK,77,77,50,14
    LTEXT           "Trust to User (T2U) v1.0\n\n(c) Copyright 2003, 2004",
                    IDC_STATIC,72,32,120,32
    ICON            IDR_MAINFRAME,IDC_STATIC,25,27,20,20
    GROUPBOX        "",IDC_STATIC,7,3,191,69
    LTEXT           "OK soft  GmbH",IDC_OK_SOFT_GMBH,72,16,120,8
END

如果您使用“MS Shell Dlg 2”或“MS Shell Dlg”而不是字体“Tahoma”，您会收到国际化的最佳结果，但也可以直接使用“Tahoma”：

FONT 8, "Tahoma"

您应该将“MS Shell Dlg 2”与标记DS_SHELLFONT或DS_FIXEDSYS和DS_SETFONT的组合使用（请参阅http://blogs.msdn.com/oldnewthing/archive/2005/02/07/368423.aspx），以便使用“ Tahoma“在大多数计算机上（在注册表项HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes下验证”MS Shell Dlg 2“值）。请阅读http://msdn.microsoft.com/en-us/library/dd374112%28v=VS.85%29.aspx或http://support.microsoft.com/kb/282187/en。

顺便说一句，您可以打开与Visual Studio相关的EXE，DLL或EXE.MUI / DLL.MUI中保存的资源。您应该只需打开文件并选择“打开方式”，然后选择“资源编辑器”。在Window 7上，您可以搜索C:\Windows\winsxs\x86_microsoft-windows-notepad并打开像C:\Windows\winsxs\x86_microsoft-windows-notepad.resources_31bf3856ad364e35_6.1.7600.16385_en-us_1dbc2e35304db501\notepad.exe.mui这样的文件。然后，您可以将文件保存为notepad.rc，然后在文本编辑器中打开文件notepad.rc，您将找到以下片段

15 DIALOGEX 30, 17, 300, 22
STYLE DS_SETFONT | DS_3DLOOK | DS_CONTROL | WS_CHILD | WS_CLIPSIBLINGS
FONT 8, "MS Shell Dlg", 0, 0, 0x0
BEGIN
    LTEXT           "&Encoding:",259,68,1,40,40,NOT WS_GROUP
    COMBOBOX        257,130,0,164,100,CBS_DROPDOWNLIST | WS_VSCROLL | WS_GROUP | WS_TABSTOP
END

    LTEXT           "With genuine Windows you have access to all Windows updates and can be confident that your Windows software has the latest security and reliability enhancements from Microsoft.",-1,0,35,250,30
    CONTROL         51209,-1,"Static",SS_BITMAP,260,10,100,55
    CONTROL         "&Resolve online now",51201,"Button",BS_COMMANDLINK | BS_LEFT | WS_TABSTOP,0,75,250,24
    CONTROL         "<a>Read the privacy statement online</a>",51202,"SysLink",WS_TABSTOP,0,128,120,10
END

更新：尝试将WndProc功能修改为以下内容：

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
  static HWND hwndEdit;
  static HWND hwndButton;
  static int len;
  static TCHAR text[30];
  HFONT hFont;
  LOGFONT lf;

  switch(msg)
  {
    case WM_CREATE:
    hwndEdit = CreateWindow(TEXT("Edit"), NULL, WS_CHILD | WS_VISIBLE | WS_BORDER,
                50, 50, 150, 20, hwnd, (HMENU) ID_EDIT,
                NULL, NULL);
    GetObject (GetStockObject(DEFAULT_GUI_FONT), sizeof(LOGFONT), &lf); 
    hFont = CreateFont (lf.lfHeight, lf.lfWidth, 
        lf.lfEscapement, lf.lfOrientation, lf.lfWeight, 
        lf.lfItalic, lf.lfUnderline, lf.lfStrikeOut, lf.lfCharSet, 
        lf.lfOutPrecision, lf.lfClipPrecision, lf.lfQuality, 
        lf.lfPitchAndFamily, lf.lfFaceName); 

    SendMessage (hwndEdit, WM_SETFONT, (WPARAM)hFont, TRUE);

    hwndButton = CreateWindow(
        TEXT("button"), TEXT("Set Title"),       
        WS_VISIBLE | WS_CHILD,  
        50, 100, 80, 25,        
        hwnd, (HMENU) ID_BUTTON, NULL, NULL);      

    SendMessage (hwndButton, WM_SETFONT, (WPARAM)hFont, TRUE);
    break;


    case WM_DESTROY:
        PostQuitMessage(0);
    break;
  }
  return DefWindowProc(hwnd, msg, wParam, lParam);
}

Answer 2

您可以通过发送WM_SETFONT消息来设置窗口的字体：

HWND myButton = CreateWindowEx(/* ... */);
HFONT myFont  = /* ... load font from somewhere ... */

/* Change the button font. */
SendMessage(myButton, WM_SETFONT, WPARAM(myFont), TRUE);

这种方法可让您逐个控制地控制您正在使用的字体，但每个窗口只需要执行一次。
