I believe this is auto-generated code from the previous JUCE version I was using, but don’t recall (maybe I manually copied and pasted this from elsewhere). I’m unfamiliar with `std::unique_ptr`, so any quick tips for this issue would be greatly appreciated. ![36%20AM](https://us1.discourse-cdn.com/flex026/uploads/juce/original/2X/0/0aad8118956f9237e83effd69afe751e388a977f.png) ---

It looks like the `Label::Listener` autogenerated code is missing a `.get()`. I’ll add that. For now, you can fix this by changing `if (labelThatHasChanged == bpmValuesLabel)` to `if (labelThatHasChanged == bpmValuesLabel.get())` ---

Get used to std::unique\_ptr as soon as you can, it’s part of C++11 101. ---

Yeah, I never used it because I always only use raw C++ pointers or one of the JUCE template pointers, never had a need to use the C++ template ones. ---

@jules, now that this change has been made in the codebase, this bullet point might need updated 🙂 “The juce::ScopedPointer class was written to be compatible with pre-C++11 compilers, so although it does offer C++11 move functionality for supported compilers, it’s not as versatile as std::unique\_ptr. So if you can use std::unique\_ptr in your own code, that’s probably a better bet. We may eventually migrate the JUCE codebase to std::unique\_ptr.” > **[Coding Standards | JUCE](https://juce.com/discover/stories/coding-standards)** > > Deliver music applications on all main platforms, with high performances and professional tools ---

Is it possible to have this committed into the codebase? The temp fix is fine, but whenever I change something in the GUI and save with the Projucer, the `.get()` is removed and it has to be manually inserted again. ---

It was - [here](https://github.com/WeAreROLI/JUCE/commit/0f94dbbf961c41bbeae143ffd42625990a0cc5bd). You’ll need to rebuild the Projucer.
