IsWindowVisible info  Overview  Group

The IsWindowVisible function retrieves the visibility state of the specified window.

BOOL IsWindowVisible(

Parameters

hWnd

Identifies the window.

Return Values

If the specified window and its parent window have the WS_VISIBLE style, the return value is nonzero.

If the specified window and its parent window do not have the WS_VISIBLE style, the return value is zero. Because the return value specifies whether the window has the WS_VISIBLE style, it may be nonzero even if the window is totally obscured by other windows.

Remarks

The visibility state of a window is indicated by the WS_VISIBLE style bit. When WS_VISIBLE is set, the window is displayed and subsequent drawing into it is displayed as long as the window has the WS_VISIBLE style.

Any drawing to a window with the WS_VISIBLE style will not be displayed if the window is obscured by other windows or is clipped by its parent window.
