```
public class MSG
extends Struct
implements NativeResource
```
Contains message information from a thread's message queue.
Member documentation
- hwnd – a handle to the window whose window procedure receives the message. This member is NULL when the message is a thread message.
- message – the message identifier. Applications can only use the low word; the high word is reserved by the system.
- wParam – additional information about the message. The exact meaning depends on the value of the message member.
- lParam – additional information about the message. The exact meaning depends on the value of the message member.
- time – the time at which the message was posted
- pt – the cursor position, in screen coordinates, when the message was posted.
