Custom UI

Hi everyone,

I’m developing a custom TestStand step type and exploring ways to provide a custom configuration panel for it.
Currently, I’ve built a Qt-based DLL (using ShowSettingsPanel() in C++) that opens a popup dialog for step configuration.

I understand that TestStand allows configuration UIs through ActiveX, .NET, or CVI DLLs via the Edit Tab Controls feature. However, I’m wondering if it’s technically possible to embed a custom UI (like a Qt panel) directly inside the Step Settings tab (similar to how the built-in “Call Executable” or “Message Popup” steps show their controls).
