keyPressListener in document
There exist any method like document.addKeyPressListe开发者_开发知识库ner, DOM.addKeyPressKistener or anything else?
yes, there is document.onKeyDown
you use that with a callback function that fires after the key is pressed. Also, you can get what key was pressed as an integer pertaining to the key.

You can either use addDomHandler on the RootPanel.get() (which wraps the document's <body>) or RootLayoutPanel.get(), or use Event.addNativePreviewHandler.
