Converts screen coordinates of a specified point on the screen to client coordinates
#include <WinAPIConv.au3>
_WinAPI_ScreenToClient ( $hWnd, ByRef $tPoint )
| $hWnd | Identifies the window that be used for the conversion |
| $tPoint | $tagPOINT structure that contains the screen coordinates to be converted |
| Success: | True |
| Failure: | False |
The function uses the window identified by the $hWnd parameter and the screen coordinates given in the
$tagPOINT 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.
