GWT vs Dart – what are the main differences? Is Dart a potential replacement of GWT? [closed]

I think I found it: (should have read Dart’s FAQ first, instead of googling “GWT vs Dart”) From: http://www.dartlang.org/support/faq.html#future-for-GWT Q. What’s the future for GWT? Bruce Johnson posted on the GWT blog (with further comments on Plus): “Dart and GWT both share the goal of enabling structured web programming. In fact, many of the same … Read more

Threading in GWT (Client)

JavaScript doesn’t support multithreading. However, GWT has a class to ‘simulate’ threading, which is not real multithreading, but in most cases does what you need: com.google.gwt.core.client.Scheduler.ScheduledCommand. The technique is based on the timer class, which executes a method after the given time elapses. For example, when placing the following code in you own code, the … Read more

Differences between GWT and Vaadin

In GWT application logic is normally run on client side. It only calls server when it needs to read/save some data. In Vaadin application logic is on server side.

GWT module may need to be (re)compiled REDUX

Have you started the DevMode using your src/main/webapp as the “war folder”? or in other words, is there a *.nocache.js in your src/main/webapp? In that case, this file will overwrite the one produced by the GWT compiler as called by the gwt-maven-plugin. The *.nocache.js generated by the DevMode (when no one exists, generated by a … Read more

How do I select only visible elements using XPath?

This should work: .//button[.=’OK’ and not(ancestor::div[contains(@style,’display:none’)]) and not(ancestor::div[contains(@style,’display: none’)])] EDIT: The simpler and more efficient expression below: //div[not(contains(@style,’display:none’))]//button[.=’OK’] does not work properly because every button has at least one div that’s visible in its ancestors.

Multiple pages tutorial in Google Web Toolkit (GWT)
