  39 Although internally an MDI child frame is a child of the MDI client window, in wxWindows
  40 you create it as a child of \helpref{wxMDIParentFrame}{wxmdiparentframe}. You can usually
  41 forget that the client window exists.
  42
  43 MDI child frames are clipped to the area of the MDI client window, and may be iconized
  44 on the client window.
  45
  46 You can associate a menubar with a child frame as usual, although an MDI child doesn't display
  47 its menubar under its own title bar. The MDI parent frame's menubar will be changed to
  48 reflect the currently active child frame. If there are currently no children, the parent
  49 frame's own menubar will be displayed.

 163 \wxheading{Remarks}
 164
 165 The client window is the area where MDI child windows exist. It doesn't have to cover the whole
 166 parent frame; other windows such as toolbars and a help window might coexist with it.
 167 There can be scrollbars on a client window, which are controlled by the parent window style.
 168
 169 The {\bf wxMDIClientWindow} class is usually adequate without further derivation, and it is created
 170 automatically when the MDI parent frame is created. If the application needs to derive a new class,
 171 the function \helpref{wxMDIParentFrame::OnCreateClient}{wxmdiparentframeoncreateclient} must be
 172 overridden in order to give an opportunity to use a different class of client window.
 173
 174 Under Windows 95, the client window will automatically have a sunken border style when
 175 the active child is not maximized, and no border style when a child is maximized.

 224 An MDI (Multiple Document Interface) parent frame is a window which can contain
 225 MDI child frames in its own `desktop'. It is a convenient way to avoid window clutter,
 226 and is used in many popular Windows applications, such as Microsoft Word(TM).

 237 <wx/mdi.h>
 238
 239 \wxheading{Remarks}
 240
 241 There may be multiple MDI parent frames in a single application, but this probably only makes sense
 242 within programming development environments.
 243
 244 Child frames may be either \helpref{wxMDIChildFrame}{wxmdichildframe}, or \helpref{wxFrame}{wxframe}.
 245
 246 An MDI parent frame always has a \helpref{wxMDIClientWindow}{wxmdiclientwindow} associated with it, which
 247 is the parent for MDI client frames.
 248 This client window may be resized to accomodate non-MDI windows, as seen in Microsoft Visual C++ (TM) and
 249 Microsoft Publisher (TM), where a documentation window is placed to one side of the workspace.
 250
 251 MDI remains popular despite dire warnings from Microsoft itself that MDI is an obsolete
 252 user interface style.
 253
 254 The implementation is native in Windows, and simulated under Motif. Under Motif,
 255 the child window frames will often have a different appearance from other frames
 256 because the window decorations are simulated.

 407 \docparam{height}{Receives the client height in pixels.}
 408
 409 \wxheading{Remarks}
 410
 411 The client area is the area which may be drawn on by the programmer, excluding title bar, border, status bar,
 412 and toolbar if present.
 413
 414 If you wish to manage your own toolbar (or perhaps you have more than one),
 415 provide an {\bf OnSize} event handler. Call {\bf GetClientSize} to
 416 find how much space there is for your windows and don't forget to set the size and position
 417 of the MDI client window as well as your toolbar and other windows (but not the status bar).
 418
 419 If you have set a toolbar with \helpref{wxMDIParentFrame::SetToolbar}{wxmdiparentframesettoolbar},
 420 the client size returned will have subtracted the toolbar height. However, the available positions
 421 for the client window and other windows of the frame do not start at zero - you must add the toolbar height.
 422
 423 The position and size of the status bar and toolbar (if known to the frame) are always managed
 424 by {\bf wxMDIParentFrame}, regardless of what behaviour is defined in your {\bf OnSize} event handler.
 425 However, the client window position and size are always set in {\bf OnSize}, so if you override this
 426 event handler, make sure you deal with the client window.
 427
 428 You do not have to manage the size and position of MDI child windows, since they are managed
 429 automatically by the client window.

 482
 483 You might wish to derive from \helpref{wxMDIClientWindow}{wxmdiclientwindow} in order
 484 to implement different erase behaviour, for example, such as painting a bitmap
 485 on the background.
 486
 487 Note that it is probably impossible to have a client window that scrolls as well as painting
 488 a bitmap or pattern, since in {\bf OnScroll}, the scrollbar positions always return zero.

 501 MDI parent window. It saves the application having to manage the positioning
 502 of the toolbar MDI client window.

 508 \wxheading{Remarks}
 509
 510 When the frame is resized, the toolbar is resized to be the width of
 511 the frame client area, and the toolbar height is kept the same.
 512
 513 The parent of the toolbar must be this frame.
 514
 515 If you wish to manage your own toolbar (or perhaps you have more than one),
 516 don't call this function, and instead manage your subwindows and the MDI client window by
 517 providing an {\bf OnSize} event handler. Call \helpref{wxMDIParentFrame::GetClientSize}{wxmdiparentframegetclientsize} to
 518 find how much space there is for your windows.
 519
 520 Note that SDI (normal) frames and MDI child windows must always have their
 521 toolbars managed by the application.

 533 the frame when you call this function.
