*
* - {@code hwnd} – a handle to the window whose window procedure receives the message. This member is {@code NULL} when the message is a thread message.
* - {@code message} – the message identifier. Applications can only use the low word; the high word is reserved by the system.
* - {@code wParam} – additional information about the message. The exact meaning depends on the value of the message member.
* - {@code lParam} – additional information about the message. The exact meaning depends on the value of the message member.
* - {@code time} – the time at which the message was posted
* - {@code pt} – the cursor position, in screen coordinates, when the message was posted.
