IsWindowVisible
The IsWindowVisible
function retrieves the visibility state of the specified window.
BOOL IsWindowVisible(
|
HWND hWnd |
// handle of window |
|
); |
|
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.
