我尝试编写简单的 show_window 函数,但是使用宽字符的函数,在 D 中没有任何示例,只有我能找到使用窄字符串的窗口创建并现在尝试重写它(我知道英语不好)。因此,即使正确注册 unicode winapi 绑定,我也失败了。
import core.runtime;
import core.sys.windows.windows;
import std.c.windows.windows;
pragma(lib, "gdi32.lib");
pragma(lib, "user32.lib");
struct WNDCLASSW { UINT style; WNDPROC lpfnWndProc; int cbClsExtra; int cbWndExtra; HINSTANCE hInstance; HICON hIcon; HCURSOR hCursor; HBRUSH hbrBackground; LPCWSTR lpszMenuName; LPCWSTR lpszClassName; }
extern(Windows) HWND CreateWindowW(LPCWSTR lpClassName, LPCWSTR lpWindowName, DWORD dwStyle, int x, int y, int nWidth, int nHeight, HWND hWndParent, HMENU hMenu, HINSTANCE hInstance, LPVOID lpParam );
extern(Windows)
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int iCmdShow) {
HWND hWnd = CreateWindowW("wndClassName",
"window caption", WS_SYSMENU | WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, HWND_DESKTOP, null, hInstance, null);
return 0;
}
这会产生:
Error 42: Symbol Undefined _CreateWindowW@44
