WM_WINDOWPOSCHANGED

  • Article

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 windows 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

Runs on Versions Defined in Include Link to
Windows CE OS 1.0 and later Winuser.h    

Note   This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.
