           Summary: mdi: creating child during wm_create of frame window
           Product: Wine
           Version: 20050628
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-gui
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: T.Bonner at freesurf.ch


Took the Petzold-Code describing MDI, modified it to have a child window opened
right at startup (wm_create of the frame window proc has been modified):

[original petzold code: mdidemo.c]
[...]
     switch (iMsg)
          {
          case WM_CREATE :          // Create the client window

               clientcreate.hWindowMenu  = hMenuInitWindow ;
               clientcreate.idFirstChild = IDM_FIRSTCHILD ;

               hwndClient = CreateWindow ("MDICLIENT", NULL,
                              WS_CHILD | WS_CLIPCHILDREN | WS_VISIBLE,
                              0, 0, 0, 0, hwnd, (HMENU) 1, hInst,
                              (LPSTR) &clientcreate) ;



               /********** new ********/
	       mdicreate.szClass = szHelloClass ;
	       mdicreate.szTitle = "First Startup Hello Window" ;
	       mdicreate.hOwner  = hInst ;
	       mdicreate.x       = 10;
	       mdicreate.y       = 10;
	       mdicreate.cx      = 300;
	       mdicreate.cy      = 100;
	       mdicreate.style   = 0 ;
	       mdicreate.lParam  = 0 ;	       
	       hwndChild = 
		 (HWND) SendMessage (hwndClient,
				     WM_MDICREATE, 0,
				     (LPARAM) (LPMDICREATESTRUCT) &mdicreate);
               /***********************************************/


               return 0 ;

          case WM_COMMAND :
[...]

On Windows, child window is showing up with its full size, on linux/wine this
child window has zero size.
