When forking regions, copying playlists or saving snapshots we do not
have a reference to the track and cannot use the track's name as basis
for the new filename like Editor::fork_region() does.
A cloned midi region's name is based on the original region name.
This prevents endless addition "name-1-1-1-1-1-1-1-1.mid", adding
to the region's basename.
The previous code was supposed to ensure VERSION and PROGRAM_VERSION
were *not* Unicode objects since though they are the correct type to
represent strings in Python 2, too many libraries have strange issues
dealing with them, and UnicodeErrors can creep in with implicit
conversions from/to Unicode objects.
But in fact it did exactly the contrary since str.decode() always
returns Unicode objects, whose type corresponds to the str class in
Python 3. Fix it so that in both Python 2 and 3 the constants are
eventually instances of str.
Do that by wrapping the packed controls box in a ScrolledWindow and
making it request the same width than the box but capped to 90% of the
screen width.
Also, when the box width exceeds the maximum value, try again with
one-letter automation buttons in case the reduced width avoids showing a
scroll bar.
The queued resize will only happen trigger a size-request when the
widget is realized, and on_size_request() calls ensure_layout().
Moreover, this over protection meant that sometimes a resize wasn't
noticed by the button containers.
pthread-w32 does not support pthread_setschedparam() with
SCHED_FIFO and bails out. While pthread_create() simply ignores the policy
and sets the priority regadless.
This only affects ctrl-surface event-loops & AutomationWatch on Windows.
The generic plugin UI uses spelled-out automation state buttons for
controls, which is good for readability and usability, but some plugins
have a very big amount of controls which means we need a lot of columns.
For those plugins, prefer one-letter automation states, to save width.
When there was a knobtable in the ControlUI, the behavior of the
automation state button changed by displaying one-char state as in track
headers. Factor out that logic to depend on a new boolean property of
the ControlUI, which should be set with set_short_autostate().
This regroups sizing logic in a single place and avoids future
discrepancies between the actual caption and the size allocated for it,
when several use-cases for smaller buttons are added.
Check, in order, if the io is connected to another Ardour route, then a
user bundle, then some physical ports with simple configuration, and
lastly another client.
Before, Routes were considered connected as long as every io port
connected to that route, even if the channel order was mixed or worse if
all ports were connected to the same channel. Now Routes and Bundles are
considered connected if they are exclusively connected, in the right
order, to all their ports with matching datatype.
Add config setting for playhead-scroll-speed.
Default to 100% for now, but for new users we might later default it to something slower.
If you want to scroll quickly, it is preferred to zoom out first, then scroll.
New function session_gui_extents() reports the extents of all playlists.
ToDo: include region playlists, when they become available.
also: slow-down autoscroll (ToDo: make a config variable for this)
