Re: Global event handler

Have you taken a look at the static Event.addNativePreviewHandler method?

Example:

Event.addNativePreviewHandler(new Event.NativePreviewHandler() {

@Override

public void onPreviewNativeEvent(NativePreviewEvent event) {

switch (event.getTypeInt()) {

case Event.ONKEYDOWN:

int keyCode = event.getNativeEvent().getKeyCode();

// .....

}

}

});

I want to catch certain keypress events that get caught no matter what
widget is focused.

I have:

public class MainController {
 public void onModuleLoad()
 {
   RootLayoutPanel.get().add(new MainView());
 }
}

public class MainView extends Composite implements
HasKeyPressHandlers, KeyPressHandler {
 public MainView() {
   this.addKeyPressHandler(this);
   addManyWidgets();
 }
 void onKeyPress(...) { ... }
 HandlerResitration addKeyPressHandler(...) {  ... }
}

But the events get only caught when the focus is in a widget in
mainview and are NOT caught when I just click anywhere (thats not a
focusable widget) in the mainview.
