Fixes regression from 75077f6200 that caused
global automation tracks to have priority in processing.
Adds a test checking for the desired behaviour.
Fixes#4268
QMdiSubWindow::setSizePolicy doesn't have any effect because QMdiSubWindow
uses a layout. This patch uses QMdiSubWindow::layout()->setSizeConstraint
instead. This may cause effects that don't have a layout and don't
implement sizeHint() to now be resizable. For effects that do though, it
fixes the size constraint.
* Give our threads names
It helps with debugging.
* Use Q_OBJECT macro to automatically name threads.
By default, QThread sets its name based on the Qt meta class. To get an
accurate metaclass, the class which inherits QThread must declare
Q_OBJECT in its header. Futhermore, Qt's MOC requires that a Qt type be
the primary base class when declaring Q_OBJECT, hence the order of
base classes has been rearranged for some classes.
* Add f2 as a FX mixer rename shortcut. Enter doesn't work yet.
* Add both enter keys, remove code duplication
* Fix renaming with enter/return
* Clean up
* Horizontal mouse-wheel zooming. Ensure zoom center is always on the current mouse position.
* Horizontal zoom using mouse wheel center on the mouse position. For the SongEditor too.
* Wheel center on the Automation editor too.
Moving empty destructors out of the .cpp files and into headers
allows them to be devirtualized in certain cases.
(When the compiler can't "see" a function in a header, it must largely
assume it's some black box that the linker will resolve.)
While we're at it, use C++11's `= default` to define empty virtual
desturctors for us.
For some classes (e.g., Piano), nothing is derived from it, so we can
mark the class as final and remove any explicit virtual dtor.
There are many other places where this can be done, but this is a large
enough patch as-is.
* ThreadableJob: Move from AtomicInt to std::atomic
This is the first in a series of commits that migrates away from
AtomicInt towards the C++11 standard library types.
This would allow the removal of AtomicInt and related Qt
version-specific code.
While we're at it, also make ProcessingState an `enum class` so that
it's not implicitly convertible to integers.
* LocklessAllocator: Switch from AtomicInt to std::atomic_int
If it looks like some assignments around the Compare & Swap loops went
missing, it's because compare_exchange_weak() updates the first argument
to the current value when it fails (i.e., returns false).
* BufferManager: Remove extra AtomicInt include
* MixerWorkerThread: AtomicInt to std::atomic_int
* NotePlayHandle: AtomicInt to std::atomic_int
* Remove AtomicInt.h
* Move from QAtomicPointer to std::atomic<T*>
This removes some #ifdef trickery that was being used to get
load-acquire and store-release from Qt5 and "plain" (presumably
sequentially-consistent) loads and stores from Qt4.
