I have a toolbar implemented in my MDI application. However, my child windows
will ovelap the toolbar. Can anyone tell me how to resize the MDI client
windows so that it will not ovelapped with the toolbar. The MDI frame window is
the parent of both the toolbar window and the MDI client window!!
 
e-mail or post to newsgroup is welcome!!

The answer is to have the Toolbar window as a child of the FRAME window,
not of the MDI client.  All you have to do then is process the WM_SIZE
message in the frame window proc, and resize/move the MDI client window
yourself, rather than passing WM_SIZE on to DefFrameProc, which resizes
the MDI client to fill the client area of the frame window.

Best wishes,

Chris

1. Making a window be a son of the MDI frame is not trivial in OWL..
   I found two ways to do this:
    a. Create the child window with a null parent, then call SetParent
       to set the parent be the MDI window. (not touching the child).
    b. In the constructor of toolbar call SetFlags( WB_MDICHILD, 0).

2. All child windows that process WM_SIZE must also call the default WM_SIZE
   method to make the MDI work correctly.

Good luck !    (you'll need much if your working in MSwindows..)
