You did quite a lot of changes to Jamulus.pro
It seems to be overkill.

Can you be specific?
In this commit there are a few extra changes in Jamulus.pro included from earlier dev / simplification work. There is quite a lot of cruft IMO anyway in the .pro file, but feel free to push or suggest changes.

How do message boxes work in qml?

Closest equivalent is the Popup (https://doc.qt.io/qt-6/qml-qtquick-controls-popup.html) which I used in a few cases, see AppWindow.qml.

I don’t think we need to necessarily always have a text saying „Connected“. The state should be conveyed differently.
if the connection stands faders are visible, else not. Potentially we‘d want to say „Disconnected“ in this case.

Seems like you revert some recent changes like the pan timer.

Eesh, that's possible, I tried to avoid that but with the length of time this took me, I may have missed a few commits.

I see a few other recent changes in client.cpp, such as 49eb608. I'm not sure what this client<->server channel mapping is about, or what server channels are, or what the requirement for this was.
For things like this, it might be best to cherry-pick the relevant commits, as the number of files affected will be minimal.

It seems like some of the latest changes are reverted. The question is how we can have a clean state.

I think one of the main challenges is to keep it up to date with the changes on main.
The question is how can we progress.
In the best case, after 3.12.0 is out, we‘d have a codebase which is clean and we could make the qml changes.
|
Maybe out of scope, maybe not: We'd need to adapt the CI. |
|
I could imagine the following:
|
|
I think we can delay reverb implementation. It's not even clear if this would even be part of Jamulus 4 in the current way. The connect dialog would be more important. |
|
If I find time in the following months I'd like to look at getting the CI working. |
|
It would be interesting if #3406 could be fixed with this. I'll try a qt6 build for iOS soon. |
|
@coderabbitai review this please. Assess if we should put this onto a feature branch? |

Create the feature branch from the current Jamulus 4 baseline. Then port the QML changes in reviewable units. Do not use the existing branch tip as the long-term integration base. Use separate work items for these areas:

overrides; preserve environment-provided ANDROID_ABIS and generated or
pre-defined version codes by default, and apply the x86_64/1234
local-development values only when an explicit CONFIG+=androidlocaldev opt-in is
enabled.
- Around line 50-52: Update the Windows qmake configuration so the ASIOSDK2
existence check and ASIO source inclusion are both guarded by !contains(CONFIG,
"serveronly"). Preserve ASIO behavior for non-server Windows builds while
allowing serveronly builds to omit the SDK and ASIO implementation.
In `@src/AppWindow.qml`:
- Around line 93-97: Remove the unused onUserMsgChanged function and its
associated stale comment from the root QML component. Leave the existing
Popup.visible binding and _main.userMsg signal-driven behavior unchanged; do not
add a Connections element.
In `@src/audiomixerboard.cpp`:
- Line 550: Update CChannelFader::SetChannelInfos to compare the existing and
incoming channel names, assign cReceivedChanInfo, and emit
channelUserNameChanged only when strName changes so QML refreshes reused fader
labels.
- Around line 526-532: Update the channel-fader resolution flow around
addChannel so SetIsMyOwnFader() is applied after the fader is resolved,
regardless of whether it is reused or newly created. Preserve the channel ID
comparison with iMyChannelID and ensure the local fader receives the flag before
being used.
- Around line 556-561: Update addChannel to return the newly created
CChannelFader* and return nullptr when MAX_NUM_CHANNELS prevents creation; in
the caller, use that return value instead of vecpChanFader.back() and only
append non-null results to newVecpChanFader.
- Around line 1029-1031: Update the vecAvgLevels write in the vecpChanFader loop
to key each average by vecpChanFader[iChId]->channelID() instead of the
positional iChId index, matching the keys used by AutoAdjustAllFaderLevels.
Remove the obsolete i < iNumChannelLevels workaround while preserving the
existing average calculation.
- Around line 613-642: Replace channel-ID vector subscripting with one lookup
that returns nullptr when no matching fader exists. In src/audiomixerboard.cpp
lines 613-642, update SetFaderLevel, SetPanValue, SetFaderIsSolo, and
SetFaderIsMute to use it and return on failure; apply the lookup in
SetRemoteFaderIsMute at lines 865-867 and UpdateGainValue at lines 910-915,
comparing channelFader->channelID() with iChannelIdx. At lines 1041-1044, make
no direct change: keep passing iMyChannelID to SetFaderIsMute.
- Around line 359-371: Update CAudioMixerBoard’s initializer list to invoke the
QObject base constructor with the supplied parent argument, preserving the
existing member initialization and vector setup.
- Around line 474-476: Update removeChannel and clear to call deleteLater() on
each removed fader object before erasing or clearing the vector, using the
removed pointer rather than an index after erasure. Ensure faders are scheduled
for deletion while preserving safe QML delegate references and existing signal
behavior.
- Around line 32-35: Initialize m_isRemoteMuted explicitly to false in the
Audiomixerboard constructor initializer list, alongside m_isMuted and m_isSolo,
so setIsRemoteMuted has a defined prior value when Reset() calls
SetRemoteFaderIsMute(false).
- Around line 63-76: Update CChannelFader::setFaderLevel so
SendFaderLevelToServer is called only inside the value-change guard, after
m_faderLevel is assigned, and pass the clamped m_faderLevel rather than raw
dLevel. Preserve the existing keyboard-modifier argument.
- Line 70: Update the mixer update debug logging, including the statement in the
relevant fader-level path and the other five qDebug statements, to stop
outputting cReceivedChanInfo.strName; log channelID() instead where logging is
retained, or remove the statements.
In `@src/ChannelFader.qml`:
- Around line 135-139: Update the ChannelFader menu mapping so index 0 produces
the C++ INVALID_INDEX value and each subsequent index produces index - 1,
preserving “No group” and valid group 0 semantics. Change the Repeater model
from the hardcoded count to the exposed MAX_NUM_FADER_GROUPS + 1 value, and
update the grouping check near the menu to treat any value other than
INVALID_INDEX as grouped.
- Around line 101-104: Update the mute and solo buttons’ checked-state handling
so their visual state remains bound exclusively to the model properties, while
click handlers only request the toggle through the corresponding model setters.
Remove the checkable behavior or otherwise prevent button clicks from assigning
checked, including for both the mute button and soloButton.
- Around line 79-81: Replace the fader Slider’s onValueChanged handler with the
onMoved interaction handler, matching the pan Dial’s behavior, while keeping the
call to channelModel.setFaderLevel. Preserve the value: faderLevel binding so
model updates continue moving the control without triggering the no-send
feedback path.
In `@src/chatbox.cpp`:
- Line 94: Update the chat-history append logic around m_chatHistory so received
chat text is passed through QString::toHtmlEscaped() before any URL-wrapping
logic. Preserve only application-generated anchors, while retaining the existing
generated line-break markup.
In `@src/client.cpp`:
- Around line 221-226: Remove the earlier startup Start() block associated with
strConnOnStartupAddress, leaving Connect(strConnOnStartupAddress) as the sole
startup connection path. Ensure this Connect() call occurs only after
pSettings.Load, meter creation, and the timer/signal connections are established
so initialization uses stored settings and connection-time events are handled.
- Around line 1683-1690: Update CClient::sessionlinkText and
CClient::setSessionlinkText to use strSelectedAddress as the single backing
value: return it from the getter, compare and assign it in the setter, and emit
sessionlinkTextChanged after a changed value is assigned. Preserve the early
return when the value is unchanged and the existing Disconnect refresh behavior.
- Line 1638: Remove the disconnect-time assignment that resets
strSelectedAddress to "127.0.0.1" in Disconnect, leaving the user-selected
address unchanged so sessionName() and onConnectButtonClicked reuse it for
reconnection.
- Around line 390-392: Validate every received channel ID before indexing
channel-indexed arrays: add the MAX_NUM_CHANNELS bounds guard in
EvaluateConClientListMes and EvaluateClientIDMes for bChanIdInUse, oldGain, and
newGain, and add the same guard at the start of SetRemoteChanGain. Preserve
existing behavior for valid IDs while ignoring or safely handling invalid
one-byte IDs.
In `@src/client.h`:
- Around line 174-179: Initialize eRecorderState in the CClient constructor’s
initializer list to the appropriate default ERecorderState value, and update
recordingStatus() to compare against the named enumerator instead of the literal
3. Preserve the existing “ON”/“OFF” results.
- Line 461: Move the shutdown work from closeEvent to an explicit CClient
shutdown handler, such as OnAboutToQuit, and connect it once during construction
to QCoreApplication::aboutToQuit so audioMixerBoard.StoreAllFaderSettings() and
the existing cleanup run on application exit. Remove the misleading closeEvent
declaration and implementation, including the QCloseEvent dependency, while
preserving the current shutdown behavior.
- Around line 185-188: Update setMuteOut to emit muteOutChanged only when
bMuteOutStream actually changes, matching the existing setJitterWarn pattern so
programmatic mute updates propagate to QML without redundant notifications.
- Line 59: Remove the unused Linux-only includes from client.h, specifically
sched.h, netdb.h, and socket.h. Keep socket declarations provided transitively
by the existing src/socket.h include, without replacing them with another socket
header.
In `@src/levelmeter.cpp`:
- Line 63: Update the doubleVal property setter and getter around setDoubleVal
and doubleVal so they use the same units and writing a value returns that same
value. Preserve the internal normalized representation as needed, but ensure QML
property writes and subsequent reads do not normalize twice; use a separate
explicitly named level-in-steps setter if internal callers require normalized
input.
- Around line 31-33: Initialize m_clipStatus to false in
CLevelMeter::CLevelMeter alongside m_doubleVal, ensuring clipStatus() and its
QML binding report an inactive clip state before audio processing begins.
In `@src/main.cpp`:
- Line 916: Update the CClient construction call in main so its tenth argument
passes the parsed --mutestream flag instead of the hardcoded false; preserve the
existing argument order and ensure the bMuteStream parameter receives the
command-line value.
- Line 1055: Update the GUI branch of the CGenErr catch block in main to report
generr.GetErrorText() and return a non-zero failure code instead of continuing
to the success return. Preserve the existing non-GUI handling and use the
current error-reporting mechanism until the QML dialog is available.
- Line 818: Update application initialization to select the appropriate
application class based on the existing bUseGUI flag: construct QGuiApplication
only for GUI mode and use the non-GUI application class when --nogui is
selected, while preserving the existing bUseGUI handling elsewhere.
In `@src/resources.qrc`:
- Around line 2-4: Update the resource definitions in resources.qrc by adding
explicit file entries for the LED image assets and application icons under the
existing /png/LEDs and /png/main prefixes. Keep the /png/fader resource
unchanged, and reference the actual files rather than relying on directory
prefixes.
In `@src/settings.cpp`:
- Around line 928-934: Update setRbtBufferDelayPreferred,
setRbtBufferDelayDefault, and setRbtBufferDelaySafe to apply their respective
frame-size factors only when the boolean argument is true. In
UpdateSoundCardFrame, stop calling these setters sequentially and emit the
relevant change notifications directly so refreshing sound-card settings does
not overwrite the user’s selected buffer size.
- Line 370: Update ReadSettingsFromXML to restore the instrument, country, city,
and skill-level profile values into pClient->ChannelInfo, matching the keys
written by WriteSettingsToXML. Ensure these values are loaded before startup
settings are later persisted, preserving stored profiles across restarts.
- Around line 1075-1077: Update setSlSndCrdDev to call pClient->SetSndCrdDev
only once, storing its return value in success and using that value for the
existing check; remove the preceding duplicate call so the sound device is
initialized a single time.
In `@src/SettingsView.qml`:
- Line 140: Correct the property name in the onCurrentTextChanged handler to use
sndCardROutChannel, matching CClientSettings::setSndCardROutChannel and the
declared settings property.
- Around line 112-141: Update cbxLInChan, cbxRInChan, cbxLOutChan, and
cbxROutChan to initialize currentIndex from the corresponding backend channel
value and avoid writing settings during model or backend-driven updates. Persist
changes only from user interaction, following the existing audio-quality
ComboBox pattern, while preserving the correct left/right input and output
setting symbols.
- Around line 177-180: Update the CheckBox identified by chbDetectFeedback to
handle user toggles by calling CClientSettings::setChbDetectFeedback with the
new checked value, ensuring the persisted bEnableFeedbackDetection setting stays

- Around line 48-49: Update the alias field’s write-back handler instead of
using onTextChanged, so _settings.pedtAlias is assigned only when editing
finishes, such as via the field’s accepted or focus-loss completion signal.
Preserve the text binding to _settings.pedtAlias and avoid sending SetRemoteInfo
for each keystroke.
In `@src/sound/asio/sound.cpp`:
- Around line 312-313: Update CSound::bufferSwitch() to enforce the
minimum-cycle budget while holding ASIOMutex, safely handling processing that
exceeds the available time across capture conversion,
CSoundBase::ProcessCallback(), and playback conversion. Add a deterministic
repeated minimum-frame test that forces over-budget processing and verifies the
resulting safe behavior.
In `@src/sound/soundbase.cpp`:
- Around line 184-185: Replace the unconditional if ( true ) guard in the

In `@src/util.cpp`:
- Around line 745-749: Restore the instrument table used by GetTable() so it

Initialize m_isRemoteMuted in the constructor.
The initializer list omits m_isRemoteMuted. Reset() calls SetRemoteFaderIsMute(false), which reaches setIsRemoteMuted at Line 160. That function reads isRemoteMuted() before any write. The read is undefined behaviour, and if the indeterminate value compares equal to false, the member keeps an indeterminate value and no isRemoteMutedChanged() signal is emitted.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Send the fader level to the server only when the value changes, and clamp it first.
SendFaderLevelToServer runs outside the equality guard. Every QML write of faderLevel, including a write that repeats the current value, produces a server update. The value passed is the raw dLevel, not the clamped level stored in m_faderLevel. SetFaderLevel at Line 223 clamps with std::min before sending, so the two paths send different values for the same input.

Pass parent to the QObject base constructor.
The constructor accepts QObject* parent but the initializer list never calls QObject(parent). The object is always created without a parent, so the caller-supplied ownership is dropped and the parameter is unused.

Delete the removed fader objects.
removeChannel erases the pointer and leaves the object alive. The commented delete also uses the index after the erase, so it would delete the wrong element. clear() at Line 488 has the same defect for the whole vector. The faders stay parented to the board, keep their signal connections to OnChGainValueChanged and UpdateSoloStates, and are released only when the board is destroyed. Use deleteLater() so that any QML delegate that still holds the object is not left with a dangling pointer.

Set the own-fader flag for newly created faders.
Step 1 iterates the faders that already exist, so SetIsMyOwnFader() is applied only to those. A fader created later in Step 3 through addChannel never receives the flag during this update. On the first client list after connecting, the local fader is new, so bIsMyOwnFader stays false. SendFaderLevelToServer and SetMute then emit gainValueChanged with the wrong own-fader flag. The removed code applied SetIsMyOwnFader() at the point where a fader was put into use for a new client.
Set the flag after the fader for a channel is resolved, for both the reused and the newly created case.

🌐 Web query:
For the Qt version selected by Jamulus.pro, does a QML TextArea with textFormat: TextEdit.RichText fetch a remote URL from an img src attribute supplied through its text property?
💡 Result:
Jamulus uses Qt 6, with recent versions (as of September 2026) using Qt 6.10.2 [1]. In a QML TextArea with textFormat set to TextEdit.RichText, the component does not automatically fetch remote images from an img src attribute [2][3]. While Qt's rich text engine supports the img tag and its src attribute for rendering images [4][5], the default implementation of the underlying QTextDocument does not have built-in network access to download external resources [6][2]. When an img tag is used in a RichText component, the document looks for the resource within its internal resource system (e.g., Qt resource files or local paths) [2]. To display remote images, you must provide a custom resource handler (via a subclass of QTextDocument or by implementing a resource provider) that intercepts the request, performs the network download asynchronously, and updates the document once the image data is available [2][3]. Without such a custom implementation, the browser or text editor simply fails to resolve the URL and will not display the image [6][2].

site:doc.qt.io/qt-6 QML TextEdit RichText img src remote network resource loading QTextDocument resource provider
💡 Result:
In Qt/QML, rich text displayed within components like TextEdit or Text supports inline images via the tag [1][2]. By default, these components are capable of loading images from remote network resources (e.g., http/https URLs) [1]. However, because this functionality automatically triggers network requests, it is important to exercise caution when rendering untrusted or user-provided content [1]. To mitigate risks, you can explicitly set the textFormat to TextEdit.PlainText or ensure the content is sanitized to remove
tags before display [1]. For advanced control over how resources—such as images—are loaded, resolved, or cached, you can use the QTextDocument resource provider mechanism [3][4]. 1. Resource Provider Mechanism: Instead of subclassing QTextDocument and overriding loadResource, modern Qt (since 6.1) allows you to set a custom ResourceProvider function [3][4]. This function is a callback that the document invokes when it needs to resolve a resource URL [3]. 2. Implementation: You can assign a resource provider to a QTextDocument (or set a default one globally) [3]. When the engine encounters an
tag, it calls your provider, allowing you to intercept the request, fetch the data manually, or return a local replacement [3]. 3. QML Integration: While the TextEdit/Text components manage their own QTextDocument (accessible via textDocument) [5], customizing the resource loading behavior for rich text often involves interacting with the underlying C++ QTextDocument API where the resource provider is configured [3][4]. For general QML image loading (e.g., using the Image type), Qt provides native network transparency, meaning it automatically handles remote URLs asynchronously without requiring special configuration beyond providing the URL [6][7]. The rich text
tag support relies on the same underlying resource loading system provided by QTextDocument [2][3].

💡 Result:
The macOS TextEdit application does not support embedding or displaying remote images via URLs in Rich Text (RTF) documents. When you insert an image into a TextEdit document, the application embeds the image file directly into the document data rather than creating a dynamic link to a remote source. The information returned in the search results regarding "TextEdit" and remote images refers to the "TextEdit" component within the Qt framework (a cross-platform software development toolkit), which is unrelated to the native macOS TextEdit application. There is no evidence that the standard macOS TextEdit app possesses the capability to fetch or render images from external web addresses.

💡 Result:
In Qt QML, you can include images within a Text element by using the img tag when the text format is set to a mode that supports rich text [1][2]. Key considerations include: 1. Text Format: The Text element's textFormat property must be set to Text.StyledText, Text.RichText, or Text.MarkdownText [1][3]. By default, Text will attempt to auto-detect the format, but explicitly setting it is often safer and more performant [1][2]. 2. The img Tag: You can embed images using standard HTML-style img tags within the text string, such as: 
[1][4]. 3. Supported Formats: The image source can be a local file, a resource (e.g., "qrc:/"), or a remote URL [1][5]. Note that loading images remotely over the network will cause the text to reload, which may affect performance [1]. 4. Security Warning: Because Text elements in these modes support rich text features (including remote image loading), be cautious when displaying user-controlled or untrusted content [1]. Always sanitize such input or use Text.PlainText when possible to prevent security vulnerabilities [1]. If you require full HTML support, rendering, or advanced manipulation beyond what the Text element provides, consider using the Qt WebEngine module instead [2]. For displaying standalone images outside of a text block, the dedicated Image QML type is the standard and preferred approach [5].

github jamulussoftware jamulus src/sound/asio/sound.cpp bufferSwitch ProcessCallback
💡 Result:
In the Jamulus codebase, the bufferSwitch function corresponds to the required callback defined in the Steinberg ASIO SDK [1][2]. It serves as the primary entry point for the audio engine's processing cycle [1]. When the ASIO driver needs to transfer audio data, it triggers bufferSwitch to notify the application that both input and output buffers are ready to be processed [1][2]. Within the context of Jamulus's Windows implementation (typically found in files such as windows/sound.cpp), the bufferSwitch callback manages the synchronized exchange of audio data with the sound card driver [3][1]. Specifically: 1. Data Exchange: It receives a doubleBufferIndex, which indicates which buffer half is currently available for processing [1]. The host (Jamulus) is responsible for reading input data from the driver and filling the corresponding output buffer within this callback [1][2]. 2. Processing Context: The callback is often executed at a high-priority interrupt level for maximum efficiency [1][2]. Because of this timing sensitivity, operations within the callback must be extremely fast to avoid audio dropouts (underruns/overruns) [1][4]. 3. Integration with Jamulus: Jamulus bridges this low-level ASIO callback to its internal audio processing logic (often through methods like ProcessSndCrdAudioData) to handle tasks like channel mixing, format conversion, and synchronization with the client's internal audio threads [3][5]. Due to the critical nature of this callback, Jamulus developers must carefully manage thread safety and resource locking, as evidenced by efforts to avoid deadlocks (such as with ASIO4ALL drivers) by using mechanisms like Qt::QueuedConnection for signaling re-initialization requests, ensuring that UI or main-thread events do not interfere with the high-priority audio thread [6].

Add minimum-cycle protection to CSound::bufferSwitch().
CSound::bufferSwitch() performs capture conversion, calls CSoundBase::ProcessCallback(), and performs playback conversion while holding ASIOMutex. CSoundBase::ProcessCallback() only invokes fpProcessCallback() and has no timing guard. At 64 samples and 48 kHz, this path can exceed the 1.333 ms cycle budget. Add safe handling when the budget is exhausted. Add a deterministic repeated minimum-frame test that forces over-budget processing and records the safe result.

COSUtil::GetOperatingSystem() checks __APPLE__ before an iOS-specific condition. An iOS build can therefore return OT_MAC_OS and report "MacOS" instead of "iOS". The project already uses Q_OS_IOS and Q_OS_ANDROID for target selection. Check Q_OS_IOS before the Apple branch, use Q_OS_ANDROID for Android, and test both protocol values.

Windows builds now fail without the ASIO SDK, including server-only and headless builds.
The win32 block requires windows/ASIOSDK2 and adds src/sound/asio/sound.cpp unconditionally. The prior branches for serveronly, headless, and native Windows audio are gone. A Windows server build (CONFIG+=serveronly) now stops with the error() call, and it also compiles the ASIO sound implementation while src/sound/soundbase.h and src/sound/soundbase.cpp are excluded from that configuration (Lines 256-260, 359-362).
Guard the ASIO requirement and the ASIO sources with !contains(CONFIG, "serveronly").

Remove the local development overrides from the Android branch.
Lines 133-135 force ANDROID_ABIS = x86_64 and ANDROID_VERSION_CODE = 1234 for every qmake run on a Windows host. That silently discards the ANDROID_ABIS environment value read at Line 121 and produces a fixed version code. A release build made on a Windows host then ships a single ABI and a dummy version code.

Qt QML auto-connect on<Signal> handler for context property object signal
💡 Result:
In QML, you cannot use an on handler directly on a context property object [1][2]. Instead, you must use a Connections object to connect to signals emitted by an object exposed via a context property [1][3]. When you expose a C++ object as a context property (e.g., using setContextProperty), it becomes accessible globally by name in QML, allowing you to call its methods, read its properties, or access its signals [1][4]. However, because the context property object is not a nested child of the QML component where you want to handle the signal, the QML engine does not automatically create an on handler scope for it [1][5]. To handle a signal from a context property object, define a Connections element and set its target to the context property name [1][2]: Connections { target: contextPropertyName onSignalName: { // Handle the signal here console.log("Signal received") } } In this syntax, replace contextPropertyName with the name used in setContextProperty and onSignalName with the CamelCase version of your C++ signal name [1][5]. This approach explicitly tells the QML engine to monitor the specified object for signal emissions [1][6].

site:doc.qt.io QML context property signal handler Connections element onSignal function context property
💡 Result:
In QML, the Connections element is the recommended way to connect to signals from objects, including those injected via context properties [1][2]. To handle a signal within a Connections element, you should use the function syntax rather than the older signal handler (onSignal) syntax [3][4]. Using the function syntax is preferred because defining signal handlers directly (e.g., onDataChanged) within a Connections element is deprecated and may trigger warnings [4]. Example using the function syntax: Connections { target: contextPropertyObject function onDataChanged { console.log("The data changed!") } } Key points for context properties and Connections: 1. Target assignment: Set the target property of the Connections element to the context property (e.g., target: applicationData) [1][3]. 2. Function syntax: Use function onSignalName {} to define the handler [3][4]. This ensures better scoping and avoids issues associated with deprecated handler styles [4]. 3. Scope: When using a function, you can access the context property directly inside the function body, as it remains available within the scope of the QML file [4]. 4. Deprecation: Specifying signal handlers without the function keyword (e.g., onDataChanged:...) is discouraged for backward compatibility only and should be avoided in modern QML code [3][4]. If you mix both styles, the function definitions will be ignored in favor of the older handler style [3].

The startup connection now runs twice, and the first attempt precedes settings loading.
Lines 196-200 already call SetServerAddr and Start() when strConnOnStartupAddress is set. This new block calls Connect ( strConnOnStartupAddress ), which repeats SetServerAddr and Start().
The ordering makes the first attempt incorrect:
- The first
Start()runs beforepSettings.Loadat Line 210, so audio is initialized with default values instead of the stored user settings. - The meters
m_inputMeterLandm_inputMeterRare created at Lines 206-207, after the firstStart(). - The timer and signal connections at Lines 230-245 are established after
Connect()runs, so the connection-time state transitions have no receivers.
Remove the early Start() block at Lines 196-200 and keep only this Connect() call, placed after all connections are established.

The channel combo boxes can overwrite the loaded channel mapping.
Each channel ComboBox binds displayText but never sets currentIndex from the backend value. currentIndex stays at 0. When the model arrives or changes — for example after sndCrdInputChannelNamesChanged following a device change — currentText changes and onCurrentTextChanged writes the first channel name into the settings. The loaded left/right input and output mappings are then replaced by channel 0 and persisted by WriteSettingsToXML.
Set currentIndex from the backend value and write back only on user interaction, as the audio-quality combo box does at Line 164.

QML versus JUCEQML is the better choice for this PR. The proposed work replaces the Qt Widgets client GUI. It does not replace the audio engine, network protocol, settings system, or platform audio back ends. QML changes the presentation layer while keeping Qt integration in place. QML gives Jamulus:
JUCE has real benefits:
However, JUCE does not solve the main QML migration risks. It would require a new GUI framework, new rendering and accessibility work, new mobile packaging work, and new interaction patterns with existing Qt code. It would also require an explicit licensing and distribution review. I would only select JUCE if the project decides to replace substantial parts of the Qt-based application architecture, especially the audio and platform layers. That is a separate multi-year architectural decision. It should not be coupled to this client GUI rewrite. A key rule is required whichever GUI framework is selected:
QML animations, bindings, model updates, and JavaScript must remain outside the audio callback path. Qt threading versus C++ threadingDo not standardize on only one threading API. The repository already has both patterns:
Each API has a valid role. Use Qt threading for:
Use standard C++ threading for:
Define these rules before further refactoring:
The most important issue is real-time safety, not whether a mutex is named Move Qt 5 platforms to Qt 6 and stay on Qt 6Yes. Qt 6-only should be the target state. The current configuration is mixed:
Maintaining both major versions creates ongoing cost:
Qt 6 is the correct long-term platform for a QML client. Do not make the QML architecture depend on Qt 5 compatibility unless a required platform temporarily blocks the migration. Use staged platform work:
Do not keep Qt 5 indefinitely as a fallback. A short transition period is reasonable. A permanent dual-major policy is not. Recommended scope sequence
The concise decision is: QML for the GUI, hybrid threading with strict ownership rules, and Qt 6 as the only supported Qt major version after a staged migration. You are interacting with an AI system. |

If this branch were rebased to current main and the identified issues in your last review resolved, what would be the main benefit of moving to QML over remaining on Qt Widgets, including the custom ones used? |

Tip For best results, initiate chat on the files or code changes.
QML does not improve the audio engine, network protocol, or real-time behavior by itself. A correct Qt Widgets implementation can remain stable, performant, and maintainable. QML is more useful when the UI is state-driven and dynamic:
For Jamulus, the strongest case is the combination of a dynamic mixer and a future cross-platform client UI. The current custom widgets combine rendering, interaction, layout, and some state handling in C++. QML can make the presentation layer more replaceable and easier to adapt for different screen sizes. The main benefit is therefore architectural separation: This separation only helps if the C++ layer exposes stable models and bounded-rate UI state. In particular, meter data must be coalesced before QML consumes it. QML must not enter the audio callback path. QML also has costs:
So, after a rebase and issue resolution, I would not justify the move as “QML is technically superior to Widgets.” I would justify it only if the project wants a maintained, responsive, cross-platform client UI that will continue to change. If Jamulus expects limited UI change and primarily targets established desktop layouts, retaining Qt Widgets is the lower-risk option. If Jamulus 4 requires a redesigned client that supports desktop and mobile from one UI architecture, QML has a clear long-term benefit. You are interacting with an AI system. |

@coderabbitui so the priority is getting the architecture right first, then considering the presentation layer. If we can get the separation of concerns in place as is, we're in a better place to move to QML. |

Description of changes
NOTE: This PR is posted at the request of @ann0see, see https://github.com/orgs/jamulussoftware/discussions/3454.
It is intended as a reference or baseline to assist in the effort of converting to a QML-based version in the future.
N.B. I had to implement a freeze on new upstream merges due to the intricate nature of these changes. So it may be necessary to cherry-pick / re-implement / port any necessary upstream changes during the last 4-6 months of 2024 to the files in question, particularly client.cpp and audiomixerboard.cpp
While setting myself the challenge to learn QML, I have succeeded in rewriting the core Jamulus client GUI with QML, removing all widget code in the process.
To put it mildly, it was a large, non-trivial effort to disentangle all the widget display logic from the business logic.
All existing business logic is largely preserved, with small changes and additions here and there.
In general, things are much simplified when it comes to UI element handling. No need, for example, for the clever audiomixerboard template stuff, or creating and hiding 250 channelfader objects :)
Key Changes:
Design
The UI design is just a demo to contain all the functioning elements. It can easily be adapted as necessary.
For this reason it has almost no styling applied.
Features
All the core features of the client have been reproduced in the QML version. There may still be some subtle bugs, but it is already quite usable (only tested on Windows 11).
Exclusions
To reduce the scope of the project (already large enough) I have not implemented the following, but they should not be challenging to re-introduce:
I invite you to build and test it locally, and offer any suggestions or enhancements.
Especially on macOS as I don't have any Apple hardware at the moment.
