The winid will be created when the property clientwinid the first time will be 
read.
"
 tcustomwindowwidget = class(teventwidget)
[...]
   property clientwinid: winidty read getclientwinid;
[...]

function tcustomwindowwidget.getclientwinid: winidty;
begin
 checkclientwinid;
 result:= fclientwindow.id;
end;

procedure tcustomwindowwidget.checkclientwinid;
var
// options1: internalwindowoptionsty;
 rect1: rectty;
begin
 if fclientwindow.id = 0 then begin
  rect1:= innerwidgetrect;
  addpoint1(rect1.pos,rootpos);
  docreatewinid(window.winid,rect1,fclientwindow.id);
  if fclientwindow.id = 0 then begin
   createchildwindow;
  end;
  if fwindow <> nil then begin
   fwindow.registeronscroll({$ifdef FPC}@{$endif}windowscrolled);
  end;
  checkclientvisible;
 end;  
end;

function tcustomwindowwidget.createchildwindow: winidty;
var
 options1: internalwindowoptionsty;
 rect1: rectty;
begin
 rect1:= innerwidgetrect;
 addpoint1(rect1.pos,rootpos);
 fillchar(options1,sizeof(options1),0);
 options1.parent:= window.winid;
 guierror(gui_createwindow(rect1,options1,fclientwindow),self);
 result:= fclientwindow.id;
end;

Well, in LCL, "CreateBrowser" is called in virtual CreateWnd (this is where
X / GDI handler is requested). With MSE Twidget I had to move
"CreateBrowser" into construction because twidget.createwindow was never
called. Result was that when create TChromium control, my whole application
was cloned (even two buttons in task bar), but control by itself was not
show. When changed to twindowwidget, createwindow is also not called. In
which MSE method, X handler is received? This is not something urgent, just
curiosity, I'm thinking about some hobby project. I'll back to this case
over the weekend
