Short description of changes

Show the chat window full screen on iOS.

The dialog keeps the size from its .ui file (435×405), which is wider than a phone screen in portrait, and Qt's iOS plugin does not bring a top level window to the front when it is shown for the first time. The window therefore appeared with the wrong size, or not at all on the first tap.

ShowChatWindow() now calls showMaximized() and raise() on iOS, and skips showNormal(), which clears the maximized state again. This is the same approach the connect dialog uses since #3343.

CHANGELOG: iOS: Fixed the chat window not being shown full screen

Context: Fixes an issue?

Fixes #3383. Also addresses item 1 of #3406 (chat window proportions and overflow when rotating): the maximized state is clamped to the window bounds by Qt's iOS plugin, so it follows rotation.

Note on the close path: #3413 already changed the iOS Close action to hide() instead of close(), because close() crashed. hide() does not emit QDialog::finished, and the Chat check box is re-synchronised by the periodic UpdateDisplay(), so no additional handling is needed here.

Does this change need documentation? What needs to be documented and how?

No.

Status of this Pull Request

Working implementation.

What is missing until this pull request can be merged?

• Only verified on iOS 27 (iPhone 15 Pro, portrait and landscape, Virtual iPad).
• Android has the same .ui size problem but is deliberately not touched here; see [android] chat dialog cannot be closed #1763 for the Android close behaviour.

Checklist

Walkthrough

ShowChatWindow now maximizes and raises the chat dialog on iOS. In the forced-raise path, iOS skips showNormal(). Non-iOS platforms retain that call.

Changes: iOS chat dialog display

Layer / File(s)	Summary
Chat dialog display behavior src/clientdlg.cpp	On iOS, ShowChatWindow maximizes and raises the chat dialog. The forced-raise path skips showNormal() on iOS; non-iOS platforms retain the call. Raising and activation remain common to both paths.

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix · Severity of issue fixed: Low

Suggested labels: bug, AI

Suggested reviewers: softins

Merge Risk: Low · previous review 7c2d0

On iOS, incoming chat messages may pull the full-screen chat in front of the user's current task, such as the settings dialog. This is a narrow annoyance, not a failure of the feature. It is worth fixing before or shortly after merge.

Full details: Linked Issues check

Explanation

#3383 requires the chat dialog to display full screen on iOS. The PR summary reports that ShowChatWindow() now calls showMaximized() and raise() on iOS and skips showNormal(), which would clear the maximized state. These changes address the issue’s display-size requirement and first-show behavior.

Full details: Out of Scope Changes check

Explanation

The reported changes are limited to the iOS chat-window display path in src/clientdlg.cpp. Maximizing and raising the chat dialog directly support #3383. The PR description identifies Android as out of scope, and the summary reports no Android changes.

Full details: Description check

Explanation

The description covers the change, changelog, issue context, documentation, implementation status, remaining work, and checklist. The GitHub-checks item is still unchecked, but the description is otherwise complete.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 1 files.

Respect bForceRaise for ordinary messages.

On iOS, an ordinary message can raise the maximized chat over settings because the new ChatDlg.raise() runs when bForceRaise is false. Avoid forcing an already visible chat upfront for ordinary messages. Retain the first-show behavior and forced raises for welcome messages and explicit requests.

Part of the Qt 6 iOS set with #3987 and #3988.

Without this, the chat dialog keeps the size from chatdlgbase.ui (435×405), which is wider than a phone screen in portrait, and the first show() leaves it behind the main window, so it does not appear. Verified on an iPhone 15 Pro in portrait and landscape, and on the iOS simulator.

An iOS release built with Qt 6 needs this together with #3988.

We might also want to investigate if we can revert the hide() workaround.

Verified on an iPhone 15 Pro (portrait and landscape), the iPad Pro simulator and the Apple Vision Pro simulator (in "Designed for iPad" mode): the chat opens full screen on the first tap, closes via its Close menu, and reopens.

One related finding: the hide() workaround from #3413 has to stay. Reverting CChatDlg::OnCloseClicked() to close() on iOS reproduces a crash on Qt 6.11.1, on the first touch after reopening:

EXC_BAD_ACCESS (SIGSEGV), address 0x8
  QCoreApplication::sendEvent(QObject*, QEvent*)
  querySelection()
  -[QIOSSelectionRecognizer acceptTouchesBegan:]

That is Qt's iOS platform plugin, not Jamulus code, so this PR leaves OnCloseClicked() alone.

@ann0see Your later test indicates that the workaround should stay. Replacing hide() with close() reproduced a crash on Qt 6.11.1 when you touched the screen after reopening chat.

CChatDlg::OnCloseClicked() uses hide() on iOS in src/chatdlg.cpp (Line 185). PR #3413 introduced it for a similar crash. The stack reaches Qt’s iOS selection handler, but the root cause is not yet confirmed.

If a future Qt update may fix this, retest the open, close, reopen, and touch sequence on the target iOS and Qt versions before removing the workaround. I could not run an iOS test in the sandbox.

Learning: Within repository "jamulussoftware/jamulus", only for files matching one of ["src/chatdlg.cpp"]: When reviewing a change that replaces `hide()` with `close()` in the iOS branch of `CChatDlg::OnCloseClicked()`, require an iOS test that opens chat, closes it, reopens it, and touches the screen without a crash. Include Qt 6.11.1 if it remains a supported target. If that behavior is not verified, retain the workaround.

Learning: In Jamulus, Qt 5 does not itself prevent C++17 use. `Jamulus.pro` currently enables C++17 for Android because Oboe requires it, while the Unix scope, including the current iOS Qt 5 build, selects C++11. `CONTRIBUTING.md` requires C++11 compatibility as project policy. The iOS Qt 6 black-screen and UI stability problems are tracked separately in GitHub issue #3406; Qt 6 has worked on some historical iOS toolchain combinations, so the failure is version and toolchain dependent.
