This is pretty much Gtkmm's
* CheckMenuElem::CheckMenuElem
* MenuElem::MenuElem
except MenuItems are created with bool mnemonic = false;

The vast majority of errors reported by users as
"Cannot configure audio/midi engine with session parameters"
have nothing to do with engine-parameters.

Fix potential crashes in case fluid-synth runs into an OOM error,
and address a const-cast compiler warning.
Switch to track github repo (instead of sf.net git)

The drawing itself should be unchanged but much of the rest of the
implementation has changed. The WaveViewThreads and WaveViewDrawingThread
classes were added and allow multiple drawing threads.
The Item::prepare_for_render interface is implemented by WaveView to enable
queuing draw requests for the drawing threads to process as soon as the state
change occurs during Editor::visual_changer, which often means the images will
be finished by the time they are needed in WaveView::render. This can
significantly reduce total render time and also flickering caused by images not
being ready for display.
If the drawing thread/s cannot finish the request by the time it is required in
WaveView::render then cancel it and draw the WaveViewImage in the GUI thread if
it is likely it can be completed in the current render pass/frame. This change
also helps reduce the flickering caused by images not being ready with threaded
rendering, but with several drawing threads, drawing in the GUI thread may not
often occur (unless explicitly requested).
Allow unfinished images to be returned from the cache in
WaveView::prepare_for_render so that new draw requests aren't queued for
duplicate images. This reduces the amount of drawing for instance in
compositions where there are many instances of the same sample/waveform
displayed on the canvas as only a single image should be drawn.
Use a random width within a certain range for
WaveView::optimal_image_width_samples so that image drawing is less likely to
occur at the same time (which will cause a spike in render/draw time and
increase the chance of flickering waveforms).
Move implementations of the private WaveView classes into wave_view_private.h
and wave_view_private.cc source files.
Incorporate a fix for limiting the waveview image size to the cairo image size
limit.
Should hopefully Resolve: #6478

Initial use is for the WaveView class to determine whether on not to draw the
waveform in the GUI thread.

intersect
Refactor GtkCanvas::request_redraw to use Rect::intersection
|
|
Called when an item has requested a redraw and intersects with visible
canvas area.
Also add Canvas::prepare_for_render that will call Item::prepare_for_render for
items visible on the canvas.
|
|
Emitted by the canvas immediately before rendering.

Connections are remembered by ARDOUR::Port to re-establish at load.
|
|
This fixes an issue with port-connections being polled from the backend
even when it's not running.

This is in preparation for cloning MIDI-sources during snapshot save.

This may need some small tweaks for MB channelstrip to set
print-format (like LV2 plugins would) for cases where the default
value_as_string() differs.

Do not use AutomationType to identify parameters, use complete
Evoral::Parameter and Automatable.
For "batch connections", a Slavables needs to implement an API to return
the relevant controls.
This is only a first step towards a more generic Master/Slave framework.

Let the plugin implementation of Plugin::add_state use a LocaleGuard if it is
necessary (VST/LV2). This puts the LocaleGuards where they are required but the
LocaleGuards in Session::set/get_state will mean these LocaleGuards are a noop.
They are still useful for documentation purposes and in case the code is called
from a non-Session context at some point.
|
|
String <-> type conversion is being performed by the pbd/string_convert.h API
via PBD::XMLNode so LocaleGuards are not necessary.
|
|
VSTPlugin::set_state and VSTPlugin::add_state methods both already contain
LocaleGuard instances.
|
|
Using stringstream for this is not locale independant. If this constructor is
needed at a later stage it should be reimplemented.
|
|
Add to source files that use LocaleGuard
Results in far less recompiling when pbd/locale_guard.h changes
|
|
|
|
float <=> string conversion now done using PBD::to_string/string_to so
LocaleGuards are no longer needed.
|
|
All Panner implementations using PBD::to_string/string_to for float <=> string
conversion and no longer require a LocaleGuard.
