[Bug Report] Button with action "onetrack" DOES NOT work correctly

2024-01-14 10:19:58

In trying new skinning on the newer version (1.5 (6), iOS 16.1.1) of fb2k for mobile,
I have found that the [button] element with action "onetrack" does not work correctly.

I first learned that we can specify the onetrack action for the [button] element by reading the wiki on the new skinning format.

[button]
Interactive button. Parameters:
coordinates - Left,Top,Width,Height coordinates of the button rectangle.
action - What the button does. Possible values: playnpause, play, pause, stop, skipnext, skipback, menu, repeat, shuffle, onetrack, stopaftercurrent
image - Normal button image.
image-hot - Hot button image.
image2 - Alternate button image.
image2-hot - Alternate hot button image.

When I was creating skins in the old skinning format, I had not seen any documentation mentioning such usage.
However, this feature is very useful and welcome for users who want to loop the same song!!

I immediately tried it, but found that [button] with onetrack action actually does not work correctly.

More specifically, the state of the Playback Order is reflected on the button (the button image switches between on and off states),
but it does not accept any operations from the Playback screen (the button image does not switch in response to tapping the button).

I guess that parsing the skin file is okay because the button reflects the Playback Order state,
but that there is some kind of glitch in the internal processing in the application.
