ScreenToClient
The ScreenToClient function converts the screen coordinates of a specified point on the screen
to client coordinates.
BOOL ScreenToClient(
HWND hWnd,
| // window handle for source coordinates
| LPPOINT lpPoint
| // address of structure containing coordinates
| );
|
|
Parameters
hWnd
Identifies the window whose client area will be used for the conversion.
lpPoint
Points to a POINT structure that contains the screen coordinates to be converted.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Remarks
The function uses the window identified by the hWnd parameter and the screen coordinates given in the POINT structure to compute client coordinates. It then replaces the screen
coordinates with the client coordinates. The new coordinates are relative to the
upper-left corner of the specified window's client area.
The ScreenToClient function assumes the specified point is in screen coordinates.
