library UI not updating when data changes

[Owen Williams]

With the new library code, changes made to library data not triggered by the user are not reflected in the UI. This includes: scanning new files, bpm detection. Manually triggering a refresh of the data (like by editing a field and hitting escape) causes the data to appear correctly.

This looks like a problem with the engine not signalling the UI to redraw correctly.

Yup, I know why this happens and in general have a plan to fix it.

[RJ Skerry-Ryan (rryan)]

This is really two separate bugs:

1) Added tracks (scanner, drag-n-drop, iTunes, etc.) do not automatically become cached by BaseTrackCache
2) Tracks in a library table that are already in the BaseTrackCache do not update when they are modified by Mixxx.

Fix for 2 is coming and workaround for 1 are on the way.

[RJ Skerry-Ryan (rryan)]

Proper fixes in place:

- Added tracks /except/ library scanner are automatically cached in BTC
- Tracks not in the BTC get automatically cached on first touch as a last-ditch prevention for showing blank cells.

Marking this one fixed since Bug #870544 specifically talks about the library scanner case.

If I double click to load a track, the Played checkbox does not appear checked and the Play count does not increase by one. So this isn't quite fixed.

I haven't merged to trunk yet (fell asleep while trying to last night :) ).
Are you trying in 1.9 ?

nope, was using trunk. sleep is an acceptable explanation for this oversight so I'll let it go this time...

:)

Should be merged now

I don't know if this is related, but it's hard to click the "played" checkbox to toggle that state. It seems to take two or three clicks for the checkbox to end up either off or on, whichever I want. Could this be because the UI still isn't updating correctly in response to these clicks, or is it a separate issue?

The other instances of the UI not updating have been fixed, so that's all good.

Something does seem to be wrong w/ the played checkbox -- I'll have to look
into it.

Mixxx now uses GitHub for bug tracking. This bug has been migrated to:
