Unter Windows könntet man es so machen:
| C++: |
#include <windows.h>
LRESULT CALLBACK MainProc(HWND,UINT,WPARAM,LPARAM);
void HalloWelt();
struct GLOBALS
{
HWND hMainWindow;
}g_={NULL};
APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE,
LPSTR,
int nCmdShow)
{
MSG Msg;
WNDCLASS wc;
memset(&wc,0,sizeof(WNDCLASS));
wc.hbrBackground = (HBRUSH) COLOR_WINDOWFRAME;
wc.hCursor = LoadCursor(0,IDC_ARROW);
wc.hInstance = hInstance;
wc.lpfnWndProc = MainProc;
wc.lpszClassName = "HalloWelt";
wc.style = CS_BYTEALIGNCLIENT;
if (!RegisterClass(&wc))
return false;
g_.hMainWindow = CreateWindow("HalloWelt","Hallo Welt",
WS_OVERLAPPEDWINDOW,
300,300,
350,200,
GetDesktopWindow(),0,
hInstance,0);
ShowWindow(g_.hMainWindow,nCmdShow);
UpdateWindow(g_.hMainWindow);
HalloWelt();
while(GetMessage(&Msg,0,0,0))
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}
LRESULT CALLBACK MainProc(HWND hWnd,UINT Msg,WPARAM wParam, LPARAM lParam)
{
switch(Msg)
{
case WM_DESTROY:
{
PostQuitMessage(0);
return 0;
}
case WM_ACTIVATE:
{
HalloWelt();
return 0;
}
default:
return DefWindowProc(hWnd,Msg,wParam,lParam);
}
}
void HalloWelt()
{
HDC hDC = GetDC(g_.hMainWindow);
TextOut(hDC,50,20,"Hallo Welt!",11);
ReleaseDC(g_.hMainWindow,hDC);
}
