James Zhou 2000: How to create fullscreen window without title bar

Monday, November 25, 2013

The use of WS_POPUP | WS_MAXIMIZEBOX sets the window properties and allowing us to create fullscreen window without title bar.

Note that GetSystemMetrics() with SM_CXSCREEN returns the screen resolution of the primary monitor.

HWND CVideoWindow::InitInstance(LPCWSTR windowName, int width, int height)

{

int x = ::GetSystemMetrics(SM_CXSCREEN) / 2 - width / 2;

int y = ::GetSystemMetrics(SM_CYSCREEN) / 2 - height / 2;

m_hWnd = CreateWindow(L"MyWindow", windowName, WS_POPUP | WS_MAXIMIZEBOX, x, y, width, height, NULL, NULL, NULL, NULL);

return m_hWnd;

}

On windows 7 platform, if using windows 7 basic, not windows classic, can use the following code to enable fullscreen mode without title bar, without scaling.

m_hWnd = CreateWindowEx(0, L"MyWindow", 0, WS_VISIBLE | WS_SYSMENU | WS_THICKFRAME, 0, 0, width, height, NULL, NULL, NULL, NULL);

SetWindowLong(m_hWnd, GWL_STYLE, 0);
