Hello everybody! Please consider the following use-case.
I want to create a form with : Login Password Submit-Button Submit-Button should be enabled only if both login and password is not empty. To implement the requirement I'm trying to use MVP as specified in GWT best practieces. Unfortunately the Button widget in GWT has no interface that can say the object can be enabled/disabled. So, we somehow should export the "EnableAble" interface from Display (MVP) for the presenter (MVP). We can do it by applying the Adapter design pattern (GoF): create a wrapper that will wrap the button and implement the custom interface - but this approach looks pretty-bad - we should write a custom wrapper for every widget we want to enable/disable. I think that all GWT widgets that can be enabled/disabled can implement the interface that has the only "setEnabled(boolean enabled)" method. What do you think about it? Maybe this suggest should be somehow placed in GWT wishlist? Can you suggest other nice ways to resolve the task? -- Kind regards, Ignat Alexeyenko.--
