This fixes a bug where selecting "Always on top" in the plugin editor
window in Cubase 11 on Windows 11 on a display with > 100% scale would
cause the editor to display with the wrong scale factor.
It seems that Cubase calls removed() then attached() on the plugin view,
destroying and recreating the editor wrapper component. The editor
opened with 100% scale, but requests from the host to set the "real"
scale factor were ignored because the JUCE wrapper thought that the
requested scale had already been applied.
Applying the cached scale factor directly after constructing the editor
keeps everything in a consistent state, and seems to resolve the issue.
This change allows mouse events (including enter and exit events) to
reach unfocused views on macOS. This matches the behaviour of unfocused
windows on Linux and Windows, where components paint in their "hovered"
states even when the application window is in the background.
As a byproduct of using tracking areas on macOS, we can remove the fake
mouse move generator.
Hosts such as REAPER normalise the program parameter value by dividing
the program value by the step count, rather than going via the
parameter's toNormalized function. To be compatible, we should use the
same scaling technique. At time of writing, the coversion process is
detailed under the heading "Conversion of normalized values" on this
page:

Adds a mechanism to notify the host that the plugin state needs saving,
using updateHostDisplay.
Also allows JUCE hosts to detect when a plugin needs its state saving
via the AudioProcessorListener.
This commit removes the various compiler-specific JUCE_DEPRECATED macros and replaces them with C++14's deprecated attribute. It also removes the JUCE_CATCH_DEPRECATED_CODE_MISUSE flag as we can rely on the override specifier catching usage of these old virtual methods, and tidies up the DOXYGEN preprocessor checks as they were inconsistent across the codebase.
Previously, updating the program or bypass parameter could cause an
out-of-bounds access into the parameter value cache. This is because
AudioProcessorParameter::getParameterIndex() was used to index into the
cache, but the parameter index could be negative for parameters that
had not been added to the AudioProcessor.
We now use the appropriate index in the cache for parameters that
have not been added to the AudioProcessor.
On some Linux distros, the audio settings dialog was opening with the
wrong size and position. The culprit seems to be the call to setSize()
which was called inside resized(). We now try to avoid calling setSize()
if we would do so inside a resized() call.
To use this feature, derive your AudioProcessor from
VST3ClientExtensions and override getPluginHasMainInput() to return
false. The main input bus will then be designated as an Aux bus, rather
than a Main bus.
This is mainly useful for synth plugins like vocoders, which may need a
sidechain audio input, but which should replace all audio on the channel
with the output of the synth, rather than mixing with the audio input.
Ideally, we want to pass shortcut keys to the component to handle, and
only fall back to invoking a menu item if the component was unable to
handle the keyboard event, or if the action was triggered by
clicking/selecting an item in the menu itself. The old implementation
tried to work out whether the action was triggered by a shortcut by
checking the event's characters and modifiers. This method was
inaccurate, because some shortcuts (such as arrow keys) may add
unexpected numpad/function modifier flags.
We now try handling shortcut keys directly in the peer, and pass events
up to the superclass (which will forward them to the main menu) if the
event could not be handled.
This commit also adjusts some Objective-C method signatures to use the
correct string encoding for the BOOL type.
