This PR fixes issues on systems where `QCursor::setPos()` has no effect
or is not reliable. These issues included knobs moving to fast on some
operating systems. Affected widgets are `Knob` and `LcdSpinBox`.
With this PR, on all operating systems, the `setPos` calls are removed and
the cursor is not hidden anymore, so the mouse keeps moving normally
when changing values of one of the widgets.
As now the previous pointer position keeps moving (instead of being reset
to the original position using `QCursor::setPos`), the mathematics that
translate pointer pixel distance to `Knob`/`LcdSpinBox` value increase
have to be changed:
* The `Knob` transition function is now linear and uses a new factor.
* `LcdSpinBox` now uses float values and saves the current float remainder
(this is actually a separate issue revealed by this fix), leading to a fluent,
non hanging movement.
This atomically unsets the MidiJack reference in AudioJack right before
MidiJack is destroyed. This avoids AudioJack using a destroyed MidiJack
object.
This patch
* makes `m_stopped` atomic
* initializes `m_stopped` correctly to `true`
* moves the initialization of `m_stopped` to the point where jack ports
are already connected
When selecting a Piano Key to mark semitones in the Piano Roll we
select key from the y position of the pop-up menu and not the mouse.
Incidentally these two are most often the same as the menu builds
from the mouse y positon and down. If there is room for it. If there
is no room downward it will create the menu so the lower part of the
frame aligns with the mouse y position.
Fixed by creating a variable to hold the pressed key before creating
the menu.
right place when it not played from the begining.
That has created a difference between the ticks and the metronome and
the sample track.
The cause of the problem was that the calculation of the frame to play
was wrong: we had calculated `framesPerTick` according to the current
engine's sample rate instead of the SampleBuffer's sample rate.
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.
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.
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.
