我正在使用C和Win32 api创建一个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;
}
如何在上面的程序中更改按钮,文本框的字体..
请帮助我.......并让我知道在win32 api中编码的一般过程....
提前致谢..
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.每个对话中也存在密切的情况.
如何创建一个关于Win32 API的对话框,你可以在这里阅读: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
您可以将更多作为一种资源保存在同一RC文件中的不同语言中:
IDD_ABOUTBOX DIALOGEX 0, 0, 205, 98
STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_CAPTION |
WS_SYSMENU
CAPTION "????????"
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
如果你使用"MS Shell Dlg 2"或"MS Shell Dlg"代替字体"Tahoma",你会收到国际化的最佳结果,但也可以直接使用"Tahoma":
FONT 8, "Tahoma"
您应与标志一起使用"MS壳牌DLG 2" DS_SHELLFONT的组合,或DS_FIXEDSYS与DS_SETFONT(见http://blogs.msdn.com/oldnewthing/archive/2005/02/07/368423.aspx)下面来的"使用Tahoma"在大多数计算机上(在注册表项下验证"MS Shell Dlg 2"值HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes).请阅读http://msdn.microsoft.com/en-us/library/dd374112%28v=VS.85%29.aspx或http://support.microsoft.com/kb/282187/en.
顺便说一下,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并打开像文件一样的文件C:\Windows\winsxs\x86_microsoft-windows-notepad.resources_31bf3856ad364e35_6.1.7600.16385_en-us_1dbc2e35304db501\notepad.exe.mui.然后您可以将文件另存为notepad.rc,然后notepad.rc在文本编辑器中打开文件,您将找到以下片段

更新:尝试将您的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);
}
您可以通过向窗口发送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);
这种方法让您可以逐个控制您正在使用的字体，但您只需在每个窗口中执行一次。
