I would have done it like this:@UiField MenuItem itm_Login;private void init (){setCommand (itm_Login,"cmd_Login"); // one line per item...}private void setCommand (MenuItem itm,String cmd){final Method m = this.class.getMethod (cmd,null);itm.setScheduledCommand(new ScheduledCommand (){public void execute (){m.invoke ...}});}Aren't there similar methods to do this?
You could use a reflection library but that will probably generate quite some code you don't need or you could annotate either your fields or your command methods with a custom annotation and write a GWT generator (or annotation processor) to generate the code for you. That would be similar to how @UiHandler binds event handlers to your @UiFields via naming conventions. However in both cases you loose compile time error checking.
Personally I would live with it until GWT understands Java8 lambda's and method references which would eliminate most anonymous classes in GWT sooner or later. To make the init() method look nicer I would think about writing it as:
void init() {
itm_Login.setScheduledCommand(executeLoginCmd());
}
private ScheduledCommand executeLoginCmd() {
return new ScheduledCommand() {
public void execute() {
// code here
}
}
}
Well ok personally I would never use MenuBar + MenuItem because I like to have real hyperlinks so I can open things in tabs. I would have used something like FlowPanel + PopupPanel to build the menu and Hyperlink + GWT Places to build the menu items.
