How to display custom JavaScript control panel in an existing Qt application

[Hobojoe]

All,
I have a legacy Qt GUI desktop application that I would like to add a panel to in order to render a custom javascript control panel I have written. The JS control panel has a bunch of buttons/pulldowns etc. that configure a process. When the user clicks submit it fires a POST like process. I have combed the examples looking for something similar to what I want to do but I haven't found one that seem to show me what I need to do.

Am I at least on the right path in choosing QWebEngineView as the class to use?

If someone could just give me a high level description of how to do this it would be most appreciated.

Hi! When you say "legacy Qt application", does this mean Qt 4.8.7 or even older?
