IsWindowVisible function
Determines the visibility state of the specified window.
Syntax
BOOL WINAPI IsWindowVisible( _In_ HWND hWnd );
Parameters
- hWnd [in]
-
Type: HWND
A handle to the window to be tested.
Return value
Type: Type: BOOL
If the specified window, its parent window, its parent's parent window, and so forth, have the WS_VISIBLE style, the return value is nonzero. Otherwise, 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.
