A question for Mac and Linux users: I'm working on a 32-note sequencer, and I stumbled on a "trick" which seems to work on Windows, but I'd like to know if it also works on Mac and Linux.
I created 32 vertical radio bars (in green), each with 26 buttons. But the buttons at the bottom of each vertical bar are covered up by horizontal radio bar (in yellow) with 32 buttons. When you click on the yellow bar, the event goes to one of the vertical green bars underneath it, and has no effect on the yellow bar. So in effect, the yellow bar is "read only", which is what I want, because I intend to use it as a progress bar when the sequencer is running. You'll also notice that every second vertical bar appears to not have any button selected, because the hidden radio button at the bottom has been selected. This is also the behaviour I want, since I can use that to indicate a rest (no note will be played).

Is this expected behaviour, or just a quirk of the Windows version? Can I rely on this behaviour across all platforms? If you have the time and you're on Mac or Linux, can you download the patch and try it?

@dfkettle Confirmed on GNU/Linux Debian.

@ingox Thanks. Any opinion on whether this is supported behaviour, or is it liable to change with a future release of Pd?

@dfkettle I believe it is supposed behavior that the lowest object receives the click and this will probably not change.

@dfkettle This behavior is documented in some objects like [nbx] as a way to get discrete steps, so it is very unlikely to ever change and is proper behavior, not just a quirk.
