Depend on Changed() signals alone, which are usually much less frequent
than rapid-timer events.
As side-effect we now need to make the widgets insensitive when
playing automation. Previously the user could not change the value because
the Timer periodically reset it.
Trim automation is planned via SlavableAC as normal AutomationMode.
Some of this code have a revival (a special "Trim+Preview" state
before merging Automation but that has to be more general than Pan & Gain.
This reverts commit b3722f7063.
In some cases ardour shows context-menu on right-mouse-button
release. In this case selecting a menu-entry should happen
with the left-mouse button (or any button?!)
Using ev->button is only correct if the menu is temporary and only
visible while the button is held, button release then activates the
menu-item.
This needs further work, in some cases allowing any button (0) to work
makes sense and overall consistency needs to be improved.
Different places use different strategies for context-menus which
don't always match the button used in the event-handler.
This is a hotfix (to make TAV context menus work again with left-click)
Tentative solution. Eventually the gain_adjustment should be moved
into the PixFader or SliderController and a dedicated API
should replace gain_adjustment.signal_value_changed()
Due to LevelMeterVBox : public LevelMeterBase, public Gtk::VBox;
LevelMeterBase::get_type() overloads Gtk::Widget::get_type(),
Glib::Object::get_type(), Atk::Implementor::get_type() etc..
Besides Ardour-style prefers not to use get_...()
Remove the LocaleGuard so that the value of LC_NUMERIC is that of the users
locale and sscanf will parse the string correctly. For instance, with a locale
like nl_NL or fr_FR where the decimal point is different than the "C" locale,
only the number up to the decimal point will be parsed by sscanf and input
values will be rounded down.
1) Disambiguate 1.0 to GAIN_COEFF_UNITY, and 0.0 to GAIN_COEFF_ZERO
2) Add GAIN_COEFF_SMALL which replaces SMALL_SIGNAL (-140dB)
3) GAIN_COEFF_SMALL can used to avoid interpolating towards -inf on a db scale
4) GAIN_COEFF_SMALL is used to detect very small (denormal?) gains and memset to zero
Shoot for roughly 30 steps for all controls.
Always keep sensible step information in ParameterDescriptor and just convert
for the UI.
This is a little weird, but it's less weird than it was before, and works.
This cleans up a lot of false-positives in static analysis
and also helps compilers to optimize code paths in general.
(tagging the fatal stingstream operator as ‘noreturn’ is
far less trivial)
