Re: Can I create GWT Widget in javascript code?

OK, it's working now with: setTimeout

https://github.com/lofidewanto/gwt-widget-jsinterop/blob/main/src/main/java/com/github/lofi/public/testcalculator-withwait.js

Now you can see in the example how to call your Widget from JavaScript... Just simple as creating that object and use as you wish...

var calculator = new Calculator("From JS withwait");
element.appendChild(calculator.getAsElement());

Cheers,

I build a simple example: https://github.com/lofidewanto/gwt-widget-jsinterop

I also found some answer in StackOverflow but it's all Java based (see the README above). What I understood is that the Widget should be called from a pure JS (VueJS or whatever JS).

• Calculator.java -- Composite Widget
• JS uses the Calculator: testcalculator-nowait.js

I use ScriptInjector to inject testcalculator-nowait.js. 

If I tried to use this JS testcalculator-withwait.js directly in index.html it seems that it cannot find the Calculator class. I have the feeling that the Calculator JsInterop hasn't been loaded but the testcalculator-withwait.js already running. Using ScriptInjector makes this possible (testcalculator-nowait.js) but I don't think, that this was the question.

Maybe Thomas could check, I'm not sure how to "wait" in JS until the JsInterop class is loaded... 

Cheers,

I would:

1. create a new *.gwt.xml with a new EntryPoint that won't launch the GWT app but instead expose a function (using JsInterop) to "run" your module
2. that function would use receive an element ID and use RootPanel.get(id) to put the GWT UI inside (that's not the only way, but definitely the easiest); ideally it would also return a function that you would call from Vue at "unmount", but could instead return the RootPanel so it could be passed to another function exposed by the module's onModuleLoad.
3. the "unmount" callback would simply call RootPanel.detachNow(rootPanel)

That way, the Vue app could actually load the GWT module immediately, but then only use it by calling its exposed function when it needs to display the GWT module; and when it no longer needs it, it should properly "detach" it.

For example:

 I have a vue app and classic gwt application,  The gwt application have lot of module .

but I only want to one module (eg: A query UI) integration  to my vue app using js

How can I done this?

Tks.
