This message is sent to a window whose size, position, or place in the z-order has changed as a result of a call to the SetWindowPos function or another window-management function.
WM_WINDOWPOSCHANGED lpwp=(LPWINDOWPOS)lParam;
Parameters
- lpwp
Long pointer to a WINDOWPOS structure that contains information about the window's new size and position.
Return Values
An application should return zero if it processes this message.
- Default Action
The DefWindowProc function sends the WM_SIZE and WM_MOVE messages to the window.
Remarks
The WM_SIZE and WM_MOVE messages are not sent if an application handles the WM_WINDOWPOSCHANGED message without calling DefWindowProc. It is more efficient to perform any move or size change processing during the WM_WINDOWPOSCHANGED message without calling DefWindowProc.
Requirements
OS Versions: Windows CE 1.0 and later.
Header: Winuser.h.
