This fixes an issue with Mixbus. If the default "Create Audio Tracks.."
template/script is not available. Nothing is selected.
Selecting a type/template is required to update various other dialog
fields. eg. "Name" field.
Previously: Create VCA. OK+Close. Re-open dialog. Now the
implicit default was "Audio Track" but the Name-field still showed "VCA".
- _session cannot be NULL while the dialog is visible.
This removes extra `if (_session)` tests.
- Operations now no longer fail silently, but show error messages.
PluginPinWidgets initially receive their Session pointer by
PluginPinDialog::set_session(). When a RouteProcessorChange occurs all
PluginPinWidgets are recreated. Those newly created instances need a pointer to
the session.
RowReference was responsible for 75% of the cost of building the region list, and incurs cost
at every later insert/delete/reorder. Since both ListStore and TreeStore have persistent iterators,
use them instead
Experimental.
This indicates region selection:
* nudge region(s): red
* nudge playhead or marker(s): default gray
This does not indicate marker selection (nudge marker vs playhead),
nor does it change when primary-modifier is held (force playhead
nudge).
This commit does not remove this concept from the libs/ardour/engine_state_controller code,
which is used exclusively by Waves Track Live (to the extent that this can be said to
be "used").
The checkbox is not kept in sync with
Session > Properties > Timecode > JACK Time Master
besides, it relies on JACK, relies on ardour being the first jack client
and also is mostl useless due to tempo-ramps not being supported by
many jack clients.
Sometimes the interthread process window dialog reports "cancelled"
when it was not actually cancelled, it was just hidden and reshown,
Since we are polling the cancel state interthread, we must reset
the cancel status BEFORE the dialog is shown, and never toggle the
cancel state unless it is a true cancel action by the user.
