Here i post the solution.
Actually it's very easy :
HandlerRegistration logHandler =
Event.addNativePreviewHandler(new
NativePreviewHandler() {
@Override
public void onPreviewNativeEvent(NativePreviewEvent
event) {
NativeEvent ne = event.getNativeEvent();
if (ne.getCtrlKey() && (ne.getKeyCode()=='l' ||
ne.getKeyCode()=='L')) {
ne.preventDefault();
DeferredCommand.addCommand(new
Command() {
@Override
public void execute() {
loggerWindow.show();
}
});
}
}
});
CTRL+l oraz CTRL+L - opens the window with log messages.
