Added
- Dynamic menu updates:
MenuItem.SetLabel(), SetChecked(), SetDisabled(), SetIcon() — update native menu items in-place without rebuilding the entire menu (Qt6 QAction pattern)
- MenuItemUpdater interface — optional platform interface for dispatching live menu updates
- Windows:
SetMenuItemInfoW for in-place menu item updates (MIIM_STRING + MIIM_STATE)
- macOS:
NSMenuItem setTitle/setState/setEnabled via itemWithTag: lookup
- Linux: D-Bus
ItemsPropertiesUpdated signal for individual menu item property changes
Fixed
- macOS multi-tray: replace global
activeTray singleton with per-instance trayRegistryMap keyed by ObjC target — each tray now correctly receives its own callbacks (#7)
- Linux multi-tray: use
dbus.ConnectSessionBus() (private connection per tray) instead of shared singleton, and unique PID-{trayID} bus name suffix per SNI spec (#7)
Changed
- Breaking:
Menu.Add(), AddCheckbox(), AddSubmenu(), AddWithIcon() now return *MenuItem instead of *Menu — enables dynamic updates on the returned item handle (#8)
Menu.AddSeparator() still returns *Menu for chaining (separators don't need dynamic updates)- deps: goffi v0.6.0 → v0.6.2
Migration
// Before (v0.1.x) — chaining:
menu := systray.NewMenu().Add("Open", fn).AddSeparator().Add("Quit", fn)
// After (v0.2.0) — Add returns *MenuItem:
menu := systray.NewMenu()
openItem := menu.Add("Open", fn)
menu.AddSeparator()
quitItem := menu.Add("Quit", fn)
// Dynamic updates (new!):
openItem.SetLabel("Open File")
quitItem.SetDisabled(true)
