embed window(glfwCreateWindow) as child to C++ MFC parent form

问题

Please refer this link

Embedding a GLFW window inside windows forms

How can the same achieved by using VC++ to embed glfw window to Parent form?

回答1:

Try this:

1. Call glfwWindowHint() to set GLFW_DECORATED and GLFW_VISIBLE to false.
2. Call glfwCreateWindow().
3. Call glfwGetWin32Window() to get the native handle of the OpenGL window.
4. Call SetParent() to set your form as the new parent of the OpenGL window.
5. Call GetWindowLong() / SetWindowLong() to remove the WS_POPUP and add the WS_CHILDWINDOW style for the OpenGL window.
6. Call ShowWindow() to finally make the OpenGL window visible.

I got this from github.com/Chronial/foo_chronflow :: EngineWindow.cpp.

You might also call SetWindowPos() to adjust the position of the OpenGL window within your form.

The link in zett42's post is dead, so here's a more complete snippet

glfwWindowHint(GLFW_DECORATED, GLFW_FALSE);
glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE);

GLFWwindow* pWindow = glfwCreateWindow(width, height, "", NULL, NULL);

HWND hwNative = glfwGetWin32Window(m_pWindow);

SetParent(hwNative, hwParentWindow);

long style = GetWindowLong(hwNative, GWL_STYLE);
style &= ~WS_POPUP; // remove popup style
style |= WS_CHILDWINDOW; // add childwindow style
SetWindowLong(hwNative, GWL_STYLE, style);

... any other initialisation code (e.g enable/disable gl features) ...

ShowWindow(hwNative, SW_SHOW);
