Hi, any tips on resizing AU plugins? I have this working on standalones and VSTs, but can’t seem to get AU sorted. Any pointers welcome. thx ---

It works for me, if I use the draggable corner. Dragging the border doesn’t work for me, even though Logic shows the resize cursors ☹ ---

I have the exact same problem. VST works fine, AU doesn’t. I’m using setScaleFactor() in my editor. Thanks ---

I use a call to setTransform() and setSize() - wasn’t aware of the setScaleFactor() call. ---

@t0m @jules Can we bother you with this question as we’re working on a commercial product that will launch soon. Should we expect that, for plugins, the setScaleFactor() should work the same for VST and AU so the window will resize with the increased/decreased editor size? Or maybe supply a possible workaround for this? Help appreciated and thanks, Milan ---

[This commit](https://github.com/WeAreROLI/JUCE/commit/52b86a0e0b248751e2f3100277b2d42b6b8e8443) makes the `AudioProcessorEditor::setScaleFactor()` behaviour in AUs consistent with VSTs. ---

The `setScaleFactor`, or also being able to resize dragging the border, like the cursor arrows suggest? ---

The `setScaleFactor()` issue, I’ve updated my post to clarify. ---

Thanks Ed! I’ve just tested it on the Audio Unit and it seems to be working 100%. In case you’re interested in what we do, we are building the plugins for Audiaire 🙂 . Much appreciated, Milan ---

Anyone have luck with `setScaleFactor()` on DAWs like Reaper? If I make a VST3 plugin and call `setScaleFactor()` my whole UI disappears until I resize Reaper’s FX window… and even then when my UI comes back it’s at a y-position that’s equal to the height of my plugin 😕
