CascadeWindows

The CascadeWindows function cascades the specified child windows of the specified parent window.

WORD WINAPI CascadeWindows(
  HWND hwndParent,        // handle to parent window
  UINT wHow,              // types of windows not to arrange
  CONST RECT *lpRect,     // rectangle to arrange windows in
  UINT cKids,             // number of windows to arrange
  const HWND FAR *lpKids  // array of window handles
);
 

Parameters

hwndParent

Handle to the parent window. If this parameter is NULL, the desktop window is assumed.

wHow

Specifies a cascade flag. The only flag currently available, MDITILE_SKIPDISABLED, prevents disabled MDI child windows from being cascaded.

lpRect

Pointer to a RECT structure that specifies the rectangular area, in client coordinates, within which the windows are arranged. This parameter can be NULL, in which case the client area of the parent window is used.

cKids

Specifies the number of elements in the array specified by the lpKids parameter. This parameter is ignored if lpKids is NULL.

lpKids

Pointer to an array of handles to the child windows to arrange. If this parameter is NULL, all child windows of the specified parent window (or of the desktop window) are arranged.

Return Values

If the function succeeds, the return value is the number of windows arranged.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

Calling CascadeWindows causes all maximized windows to be restored to their previous size.
