Fix some assumptions that source and target of a drag actions are the same
track container. Instead of looking up necessary information (track name,
type and container id) by track index, add it to the metadata.
Refactor canPasteSelection to take QDropEvent instead of the drop event's
QMimeData. Coincidentally, this fixes the method to be consistent with its
documentation.
Fixes#4844
When deciding to polyfill glibc features, check if the standard library claims to be glibc, instead of enumerating platforms in the condition. Unlike master branch which in de3b344 changes math function calls to standard, stable-1.2 keeps their glibc names and fails to build on Linux with another libc such as musl.
(Addresses #1421)
**Behaviour description:**
* Toggle step-recording mode using the dedicated icon.
* This mode is mutually exclusive with other recoding modes (record/record
accompany).
* Step-Recording while song is playing is allowed (and fun! :) ).
* When start recording, the start recording-position will be set where the
timeline curser points (quantized backwards using PianoRoll's current
quantization). If step-recording is started while the pattern is playing the
start recording-position is set to the beginning of the pattern.
* Step length is determined by the Piano Roll's current note-length (can be
changed dynamically during step-recording).
* The record-position can be moved forward/backward using the right/left keys.
* When notes are pressed on keyboard/midi-device, they will be added
temporarily ("recorded") with a length of a step. while still pressed, user
can adjust the length by steps resolution using the arrow keys (e.g. moving
right once will make the note's length 2-steps, another right press will make
the length 3-steps etc.).
* When all pressed-keys are released, the actual recording happen and the
notes are added.
* If the user press multiple notes, and release some of them for some time
which indicates it is intentional i.e. he didn't want to do a full release
to record the step but rather just change what will be recorded (I set the
"intentional release threshold" to 70 milliseconds) - these note will be
removed from current step-recording. e.g.
* Added notes are not quantized, making the addition simpler and WYSIWYG
* Similiarly to adding notes using mouse clicks, an undo-checkpoint is added
per added step and not for the whole recording as in other record modes.
The former virtuals returned `const char*`, which lead to invalid reads when
`LadspaSubPluginFeatures` returned pointers to temporary `QByteArray::data`.
Lets you set a melody pattern as visible in the background of the Piano Roll
as support when building a new pattern. The pattern is visible throughout
the session or until cleared via the provided button.
* Move m_key member of Effect into Plugin
* Pass key to Instrument ctors and instantiaters
* Add pluginKeys to all plugin selector widgets, and let them pass the keys
when instantiating the instruments; or, if the keys must be passed over
threads, pass the keys to the Engine using `Engine::setDndPluginKey()`
* As instrument plugin libraries now also need to get their key passed, their
second argument, which was always the same as the first, is now used to pass
the sub plugin keys. This affects *all* instrument plugins.
* Plugin.h: Add more virtuals to `SubPluginFeatures` in order to draw logos
and images into instrument selector widgets
* LadspaSubPluginFeatures: Implement the `displayName` virtual because the
new behaviour to resolve displayNames is to first look at the
SubPluginFeatures, which, without override, returns the superior plugin's
name (Plugin.cpp)
Additional:
* PluginFactory.h: Allow setting up search paths without discovering plugins
yet
* Plugin.h: Add full documentation (should be checked)
Switches some signal-slot connections to Qt::DirectConnection.
Now LMMS can handle loop points correctly and export samples without glitches.
Also tweaks some Mixer-related code to avoid related deadlocks on export.
Changed according to feedback from AudioBlast. The flag used to be set most of the time, now it is only set when playback starts/stops, looping is toggled, or playback jumps around.
Adjust Mixer::getPeakValues so client do not have to allocate the
variables that will store the peak values.
Adjust both existing clients: FxMixer and VisualizationWidget.
Make the oscilloscope colors available as properties so that they can be
changed via style sheets. Adjust the existing styles to use the colors
that have been hard coded previously.
Cleanup the paintEvent method of VisualizationWidget, e.g. by extracting
a method to determine the color to use for the line and by pulling
variables to the place where they are used. Fix some Clang warnings.
