> Creating a simple window in Wayland isn't much harder than in Win32. You get a wl_surface, attach a wl_buffer to it, wrap it with xdg_toplevel and handle some callbacks for resizing etc. There's some boilerplate that allows all this to be extensible in backwards-compatible ways, but nothing complex, really. simple-touch example in Weston repository has about 400 lines.
I believe the youth nowadays calls what you wrote "copium". Because creating a simple window in Win32 (a whole program, in fact) looks like this:
#ifndef UNICODE
#define UNICODE
#endif
#include
LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam);
int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PWSTR pCmdLine, int nCmdShow)
{
const wchar_t CLASS_NAME[] = L"Sample Window Class";
WNDCLASS wc = { };
wc.lpfnWndProc = WindowProc;
wc.hInstance = hInstance;
wc.lpszClassName = CLASS_NAME;
RegisterClass(&wc);
HWND hwnd = CreateWindowEx(0, CLASS_NAME, L"Hello World! Program",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
NULL, NULL, hInstance, NULL);
if (hwnd == NULL)
{
return 0;
}
ShowWindow(hwnd, nCmdShow);
MSG msg = { };
while (GetMessage(&msg, NULL, 0, 0) > 0)
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return 0;
}
LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg)
{
case WM_DESTROY:
PostQuitMessage(0);
return 0;
default:
return DefWindowProc(hwnd, uMsg, wParam, lParam);
}
}
That's significantly less than 400 lines, and requires essentially just two function calls, RegisterClass and CreateWindowEx, the rest is the message loop and its callback.
