How can I detect the operating system using GWT?

Question

Basically what I want to know is to find out if my GWT application is running on a MacOS or any other operating system, to setup the shortcuts properly using cmd on a MacOS and ctrl everywhere else.

Accepted Answer

You can use:

```
import com.google.gwt.user.client.Window.Navigator;
...

String platform = Navigator.getPlatform();
```

This returns a String (the same as JavaScript's `navigator.platform`). You can then decide on the OS similar to this script: It simply checks for the substring "Win"/"Mac"/"iPhone"/"Linux".
