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.
