I’m attempting to extend the WebBrowser widget to implement the GetSource and BindUObject/UnbindUObject functions. The former returns the HTML content and the latter respectively binds and unbinds a UObject instance to the browser to expose properties and functions to Javascript to send data between Unreal and the browser.
GetSource needs to be called asynchronously and passes a TFunction as parameter for the callback. The BindUObject function takes an FString and a UObject pointer as parameters, but the communication is asynchronous and uses “JS Future” objects to return the values. All according to the comments in the source code.
Unfortunately, I don’t know how to call GetSource to set up a callback, or how to get the results back from UObjects bound to the browser. I understand the basics of asynchronous execution and binding delegates, but since the WebBrowser uses CEF I don’t know how to work with that.
