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.
`.config/ardour5/(templates|route_templates)`.
We put as toplevel directory of the archive `templates` or
`route_templates`. Then no matter if the user imports a session template or a
route template archives, we always put them into the correct folder.
As now the user can also import route templates while the
SessionTemplateManager is visible and vice versa, we need to signal the
successful import to the corresponding template manager. Therfor we introduce
the signal TemplatesImported.
Don't use this now, except for testing as the archive format will change.
TBD:
* error handling
* check template would be overwritten by import
* dinstinguish between session and track templates
This concernes:
* LV2 states:
LV2 states are stored in the template directories and their paths are stored
int the template files using absolute paths. Therefore we have to adjust the
template-dir property of every lv2 node referring to a state dir.
* Names of route templates.
The name of the route template is stored in the first child of the xml root
node in the property `name`. This needs to be adjusted when renaming the
template.
By now we rely on that only lv2 states and the route template name need to be
adjusted on renaming a template.
Following measures:
* Split up into two classes
* TemplateDialog: the general dialog
* TemplateManager: A widget to rename and remove templates
* Make TemplateManager abstract and derive a class for session templates and
one for route templates. This is needed, as session templates and route
templates are stored in a different way. Thus we need different methods to
rename and remove them.
Goal is to a simple dialog that can rename and remove templates. This is
helpful in order to keep the template list tidy.
So far it works for session templates. Track templates tbd.
When tracks in a gain-sharing group are selected, stepping gain
up/down affected the tracks N times:
for-each selected track inc/dec gain w/grouping.
When a mix of grouped and un-grouped tracks is selected, this lead to
inconsistent gain changes.
The new approach expands the groups first. Ignoring groups is not correct
either for single selection.
Route::before_processor_for_index() uses display_to_user() which
includes the Amp.
Insert position is still be wrong with the debug mode
ProcessorBox::show_all_processors == true, but that's not a regression.
Use Editor::first_idle() which is invoked every time when a session
is loaded (via set_session). This will catch ALL successful
session loads.
Failed session-loads explicitly pop down the splash in
ARDOUR_UI::load_session.
This only leaves "abort session open" which returns to the
session-open dialog (which pops back the splash).
During ARDOUR_UI::finish(), after destroying various instances:
close_all_dialogs() -> ArdourDialog::on_response() -> GUIIdle()
The event loop recurses and may execute a previously scheduled
Editor::idle_visual_changer()
6af51b52 moved to dedicated show-editor/show-mixer actions for
keybindings because the Mixer has a dedicated handler.
For Control-surfaces a common action is still practical.
Note: This is still broken for detached windows. it currently only
toggles tabs correctly.
ARDOUR_UI::load_session() calls flush_pending() which runs
gtk_main_iteration()s until idle.
If a user selects another snapshot from the sidebar, load_session()
is called again (from a call to load session)
