Window managers do not care about widgets,,,
So maybe I am confused about the term "Window Manager" (I think I did
not introduce it here)
MS Windows does not distinguish between the window manager and
widgetset, it provides both. The Windows-provided widgets again are
windows (have a HWND...), so that the window manager must handle
*nested* windows. Also both send messages to a window's message queue
(WM_...), so that an ordinary Windows user doesn't notice a difference
between both.
X11 instead does not provide widgets itself, these must be added by
dedicated libraries (widgetsets). The communication between an
application and the window manager and an widgetset works differently,
events from both sources must be merged into the LCL message queue, for
VCL/Windows compatibility.
