feat(taskbar): add playback buttons under the windows taskbar thumbnail - #608
Conversation
Hovering WaveFlow's taskbar icon now shows previous / play-pause / next under the window preview, so playback can be driven without bringing the window back. Only the three buttons: no progress bar and no overlay badge. The taskbar reports a click as a WM_COMMAND sent to the window procedure, which tao owns. Tauri exposes no hook for it: tao's msg_hook is taken by Tauri for menu accelerators, and only sees posted messages. So setup subclasses the main window with SetWindowSubclass, next to the subclasses tao and tauri-runtime-wry already install. The toolbar goes on at TaskbarButtonCreated, and again when the window comes back from the tray. The play/pause icon follows player:state rather than the last click. Glyphs are drawn at runtime with tiny-skia, dark on a light taskbar and white on a dark one, and redrawn when the theme changes. Tooltips ride on the tray's label push and reuse existing keys, so no locale changes. The tray's play/pause toggle moves to player_actions so both surfaces share it. Closes #583

Only the Windows taskbar buttons read them, so the Linux and macOS builds failed on dead_code under -D warnings. Clippy on Windows could not see it.

…dle or ended The decoder only honours Resume while a track is paused: from Idle or Ended it has no track open and drops the command. The tray's play/pause therefore did nothing after launch or at the end of the queue, and the taskbar button inherited that when the toggle moved to player_actions. Idle and Ended now load the persisted resume point, as the in-app Play button does. The sequence moves out of the player_resume_last command into player_actions::resume_last so both paths share it.

resume_last took the pool and the profile id with two separate awaits, a sequence carried over from the player_resume_last command. A profile switch landing between them would pair one profile's resume point with the other's id in the track-changed event. require_profile_snapshot reads both under a single lock, as player_actions::step already does.

@coderabbitai No need to open one: the MPD and OS media controls follow-up is tracked in #609, with the SMTC-at-launch observation that came out of manual testing. |

Closes #583.
Hovering WaveFlow's icon in the Windows taskbar now shows previous / play-pause / next under the window preview, so playback can be driven without bringing the window back from the tray or from behind other windows.
The scope is deliberately limited to the three buttons: no progress bar on the taskbar icon and no overlay badge.
How a click gets back to the app
Adding the buttons with
ITaskbarList3::ThumbBarAddButtonsis the easy part. A click is reported asWM_COMMAND/THBN_CLICKEDsent to the window procedure, which tao owns, and Tauri has no hook for it:with_msg_hookis filled by Tauri itself (app.rs, for menu accelerators) and not exposed;GetMessageW, which are posted ones, so it would miss a sent message anyway.So
setupsubclasses the main window withSetWindowSubclass. tao (event_loop.rs) andtauri-runtime-wry(undecorated_resizing.rs) already install their own subclasses the same way. It has to run on the thread that created the window, whichsetupdoes.The module also handles these constraints:
TaskbarButtonCreated. Before the taskbar button exists,ThumbBarAddButtonsfails.mainstarts hidden, so the message first arrives at the splash handoff. It comes again when the window returns from the tray, and the toolbar is added again then.player:statelistener and the label command only update shared state, then post a registered refresh message to the window.player:state, the event the in-app button follows, not the last click: a click the engine ignores must not flip the icon.loadingis skipped so the icon doesn't flicker between two tracks.tiny-skia(already a dependency) at the small-icon size. They are near-black on a light taskbar and white on a dark one (SystemUsesLightTheme), and are redrawn onWM_SETTINGCHANGE.THUMBBUTTONtakes anHICONdirectly, so there is no image list.set_tray_labelsgainsplay/pause). They reuseplayer.controls.play/.pauseand the tray's previous / next strings, so there are no new locale keys.Other changes
lib.rstoplayer_actions::toggle_play_pause, which the tray and the taskbar buttons now share, per the invariant on non-frontend control surfaces. It usestry_stateinstead ofstate, because the taskbar calls it from a window procedure, where a panic aborts the process.IdleandEnded. The decoder only handlesAudioCmd::Resumewhile a track is paused, so the old toggle did nothing after launch or at the end of the queue. That defect predates this PR and was found in review. Those two states now load the persisted resume point, as the in-app Play button does. The sequence moved from theplayer_resume_lastcommand intoplayer_actions::resume_last, which the command now delegates to. It reads the pool and the profile id under a single lock (require_profile_snapshot). MPD and the OS media controls have the same defect; that is tracked in bug: play does nothing from mpd or the os media controls when nothing is loaded #609.windowsgains theWin32_UI_Shell,Win32_UI_WindowsAndMessaging,Win32_Graphics_GdiandWin32_System_Registryfeatures.ui.md(new section),invariants.md,crates.md,CLAUDE.md.How I tested
