Creating external GUI windows via Lua scripts no longer works as described in Qt version

[nihonjinrxs]

Describe the bug Trying to create a new OS window via a Lua script in qfceux.

In the old Win32 fceux, the IUP library was included, and is documented here and included in example script GUI-iup_example.lua via an import of the auxlib library.

In the new Qt version, I see the Qt dlls in the bin folder, but no Lua interface for them anywhere that I can import in my script. Is there a new way to do that in this new version?

To Reproduce Steps to reproduce the behavior:

1. Open Qt x64 qfceux
2. Load a ROM
3. Load the example script GUI-iup_example.lua
4. Click the 'Start' button
5. See error

Expected behavior The example script test window appears and displays as it did on prior versions.

(please complete the following information):

• OS and Version: Windows 10 Pro v21H1 (build 19043.2006)
• FCEUX: x64 Qt both 2.5.0 6c3a31a and 2.6.4 2b8c618

Additional context If there's an easier way to generate an external window via a Lua script, I'm happy to do that -- I'm just used to using this mechanism, and now that I've updated to the Qt version on my new machine, I seem to be unable to do this now. Thanks!

Note: I did reinstall the win32 version and confirm that that importable still exists, and the example script works as expected there.

Is there any alternative here? I haven't found any myself a year plus later. Would appreciate some guidance. Thanks!

Qt has its own built in scripting engine called QScriptEngine which uses the ECMAScript language. Which I believe is a javascript like language. QScript is fully integrated with the Qt's object system and allows for easy use of UI form files that can be built with Qt creator. I will post again once I have had more time to research and prove the concept.

Update on this, I have proved the concept that I can create custom UI dialogs that are backed by Qt's javascripting engine. I'm going to move forward implementing the interface.
