Vue GWT and Widgets

For easy backward compatibility it's possible to wrap any Vue GWT Component in a GWT Widget. For this you need to use VueGwtWidget.

Adding the dependency

VueGwtWidget is in it's own Maven module. If you want to use it, add this Maven Dependency to your pom.xml:

<dependency> <groupId>com.axellience</groupId> <artifactId>vue-gwt-gwt2</artifactId> <version>${vue-gwt.version}</version> </dependency> 

And this in your gwt.xml:

<inherits name='com.axellience.vuegwt.GWT2'/> 

Instantiating a DemoComponent

Let's instantiate a DemoComponent with VueGwtWidget:

GwtIndex.html

<div id="childComponentAttachPoint"></div> 

RootGwtApp.java

public class RootGwtApp implements EntryPoint { public void onModuleLoad() { // Create a VueGwtPanel, it's a regular GWT Widget and can be attached to any GWT Widget VueGwtWidget<DemoComponent> vueGwtWidget = new VueGwtWidget<>(DemoComponent.class); // Attach it to inside our DOM element RootPanel.get("childComponentAttachPoint").add(vueGwtWidget); } } 

Accessing our Vue Instance

It's even possible to interact with our instantiated Vue.

Let's say our DemoComponent has a method increaseCounter(). We can do:

VueGwtWidget<DemoComponent> vueGwtWidget = new VueGwtWidget<>(DemoComponent.class); RootPanel.get("childComponentAttachPoint").add(vueGwtWidget); vueGwtWidget.getComponent().increaseCounter(); 

Cleaning Up

If you don't need your VueGwtWidget anymore, you can destroy it's Vue instance by calling:

vueGwtWidget.getComponent().vue().$destroy();
