@d-healey great, I'll give that a go. Many thanks

@d-healey In this case, a vertical list of objects - in this case strings - as in Juce::ListBox. Over and above that, I'd really like to see how to generate my own GUI components.

Firstly, what an excellent project and a lifesaver for me:- having dumped a decade of C# / Vst code in order to build a Blackbox synth workhorse for myself. Mr Healey’s content especially is a breathe of fresh air.

I'm going to need some Listbox style functionality and wanted to checkout using External and AdditionalSourceCode. Using Hise 4.1, the tutorial application compiles and doesn't indicate any errors, but the floatingTile always has the 'ExternalTestComponent' label even when previewed or if exported as standalone.

If I bring the binary-build into MSVS and build / run it, I get an exception inside raw_misc.h specifically UndoableUIAction::setData with the processor being null. If I make a null check, then the standalone works correctly and displays the Demo component.

Before I go fiddling where I don't belong with my bad programming habits, I'm obviously doing something wrong or have some configuration askew.

I would appreciate any advice or 'pointers'.
