Persist window position and size across sessions#313
Merged
Conversation
Set NSWindow.frameAutosaveName on the main window so macOS automatically saves and restores the window frame (position + size) across app launches, including on secondary displays. The autosave name is set in WindowTabbingView.disallowTabbing(), which already configures the main NSWindow (tabbing mode, identifier, delegate). A guard ensures setFrameAutosaveName is only called once. Fixes supabitapp#268

Summary
Fixes #268 — the main window now remembers its position and size across app launches, including when placed on a secondary display.
Problem
Supacode had no window frame persistence. Every launch reset the window to fill the primary display, which is especially annoying on multi-monitor setups.
Solution
Set
NSWindow.setFrameAutosaveName("main")on the main window inWindowTabbingView.disallowTabbing(), which already configures the mainNSWindow(tabbing mode, identifier, delegate).Once an autosave name is set, macOS automatically:
UserDefaultson every move/resizeA guard (
frameAutosaveName.rawValue != WindowID.main) ensures the call is idempotent across repeatedupdateNSViewcycles.Testing
Note:
make build-appcould not run in CI-like env (no Xcode installation), but the change is a single standard NSWindow API call with no new imports.
