Add peak indicators to the mixer strips. They show the maximum peak value
that was observed and can be reset by clicking on them.
## Implementation details
The implementation works via a signal/slot mechanism. The `Fader` class
has a new signal `peakChanged` which reports peak values as
amplifications. A new class `PeakIndicator` is added which has a slot
`updatePeak` which is connected to the new signal in `Fader`.
The `PeakIndicator` inherits from `QLabel` and mainly deals with updating
the label text from the current peak value.
Add a `PeakIndicator` instance to `MixerChannelView`. Add a `reset`
method to `MixerChannelView` so that the mixer channel can be reset on
the loading of new projects, etc. The current implementation resets the
peak indicator back to -inf dbFS. The `reset` method is called in
`MixerView::clear`.
Remove the clamping in `Fader::setPeak` so that all peaks are reported.
Emit the new signal if the peak changes.
Moves the confirmation to remove mixer channels outside of `MixerView::deleteChannel` and into `MixerChannelView::removeChannel`. This is so that the confirmation only applies when the user uses the context menu to remove a channel, which is important since no confirmation should apply when, for example, the mixer view is cleared with calls to `MixerView::clear`.
Reduce code repetition in `MixerChannelView` by introducing methods that:
* Retrieve the `MixerChannel` that's associated with the view
* Check if the associated channel is the master channel
This abstracts some functionality and also reduces direct usage of the variable `m_channelIndex`.
Use Qt layouts for the mixer channels. These changes will enable several other improvements, like for example making the mixer and faders resizable, adding peak indicators, etc.
This is a squash commit which consists of the following individual commits:
* Remove extra transparency in send/receive arrows
The extra transparency was conflicting with the positioning of
the arrows in the layout
* Begin reimplementing MixerChannelView
MixerChannelView is now a combination of the
MixerLine with the previous MixerChannelView
* Adjust SendButtonIndicator to use MixerChannelView
* Remove MixerLine
- Move MixerChannelView into src/gui
* Remove MixerView::MixerChannelView
* Remove header of MixerLine
* Change MixerView.h to use MixerChannelView
Change MixerView.h to use MixerChannelView rather than MixerLine
Also do some cleanup, such as removing an unused forward declaration
of QButtonGroup
* Create EffectRackView
+ Set height of sizeHint() using MIXER_CHANNEL_HEIGHT (287)
* Remove include of MixerLine
- Include MixerChannelView
* Phase 1: Adjust MixerView to use new MixerChannelView
* Move children wigets into header file
* Phase 2: Adjust MixerView to use new MixerChannelView
* Phase 3: Adjust MixerView to use new MixerChannelView
* Phase 4: Adjust MixerView to use new MixerChannelView
* Phase 5: Adjust MixerView to use new MixerChannelView
* Phase 5: Adjust MixerView to use new MixerChannelView
* Remove places where MixerChannelView is being deleted
Before, MixerChannelView was not inherited by QWidget,
meaning it could not have a parent and had to be deleted
when necessary. Since the MixerView owns the
new MixerChannelView, this is no longer necessary.
* Replace MixerLine with MixerChannelView
- Include MixerChannelView in MixerView
* Replace setCurrentMixerLine calls with setCurrentMixerChannel around codebase
* Add event handlers in MixerChannelView
* Implement MixerChannelView::eventFilter
* Update theme styles to use MixerChannelView
* Add QColor properties from style
- Set the Qt::WA_StyledBackground attribute on
* Add effect rack to rack layout when adding channel
* Set size for MixerChannelView
- Change nullptr to this for certain widgets
- Some custom widgets may expect there to be a parent
- Add spacing in channel layout
- Increase size of mixer channel
* Retain size when widgets are hidden
* Implement paintEvent
- Rename states in SendReceiveState
* Implement send/receive arrow toggling
- Make maxTextHeight constexpr in elideName
- Remove background changing on mouse press
(is now handled in paintEvent)
* Implement renaming mixer channels
* Implement color functions
* Implement channel moving/removing functions
* Do some cleanup
Not sure if that connection with the mute model was needed, but removing
it did not seem to introduce any issues.
* Include cassert
* Replace references to MixerLine with MixerChannelView
* Reduce height
+ Make m_renameLineEdit transparent
+ Retain size when LCD is hidden
+ Remove stretch after renameLineEdit in layout
* Remove trailing whitespace
* Make m_renameLineEdit read only
+ Transpose m_renameLineEditView rectangle (with 5px offset)
* Set spacing in channel layout back to 0
* Remove sizeHint override and constant size
* Use sizeHint for mixerChannelSize
+ Leave auto fill background to false in MixerChannelView
+ Only set width for EffectRackView
* Set margins to 4 on all sides in MixerChannelView
* Move solo and mute closer to each other
Move the solo and mute buttons closer to each other in the mixer channels.
Technically this is accomplished by putting them into their own layout with minimal margins and spacing.
* Fixes for CodeFactor
* Code review changes
Mostly whitespace and formatting changes: remove tabs, remove spaces in parameter lists, remove underscores from parameter names.
Some lines have been shortened by introducing intermediate variables, e.g. in `MixerChannelView`.
`MixerView` has many changes but only related to whitespace. Spaces have been introduced for if and for statements. Whitespace at round braces has been removed everywhere in the implementation file even if a line was not touched by the intial changes.
Remove duplicate forward declaration of `MixerChannelView`.
* Adjust parameter order in MixerChannelView's constructor
Make the parent `QWidget` the first parameter as it is a Qt convention. The default parameter had to be removed due to this.
* Move styling of rename line edit into style sheets
Move the style of the `QGraphicsView` for the rename line edit from the code into the style sheets of the default and classic theme.
* More code review changes
Fix spaces between types and references/pointers, e.g. use `const QBrush& c` instead of `const QBrush & c`.
Remove underscores from parameter names.
Remove spaces near parentheses.
Replace tabs with spaces.
Introduce intermediate variable to resolve "hanging" + operator.
Replace the connection for the periodic fader updates with one that uses function pointers instead of `SIGNAL` and `SLOT`.
