[Audacity-devel] Batch commands and SelectAllIfNone

[Philip V. B. <pdv...@vi...>]

The problem I ran into is if you do batch processing on the current project, 
and don't have a time range selected, the batch commands don't do anything. 
Normal effects automatically do a OnSelectAll() if there is no selection and 
TimeSelectedFlag is set for the command.  Batch commands call 
SelectAllIfNone, but that command doesn't select all in the case where a 
zero-length time range is selected.

My solution to this was to make SelectAllIfNone also check for the time 
range selected, and if there is either no track, or no time range selected, 
it will OnSelectAll.

The only problem I would foresee is if there is an effect which will act on 
a single, entire track if a track is selected with no time range.  Then the 
batch processing would lose this ability.
