Research direction
Start by locating the Window API and its Windows, macOS, and Linux platform implementations. Review SetWindowDisplayAffinity and NSWindow.sharingType, including the stated version and ScreenCaptureKit limitations. Done means exposing Window::SetContentProtection(bool), applying the requested platform behavior, and documenting that Linux does not support it.
Written by the indexing model from the issue text.
Description
Add Window::SetContentProtection(bool) so the window's content is excluded from screenshots and screen recording, like Electron's win.setContentProtection():
- Windows:
SetWindowDisplayAffinity(hwnd, WDA_EXCLUDEFROMCAPTURE)(Windows 10 2004+, elseWDA_MONITOR) - macOS:
NSWindow.sharingType = NSWindowSharingNone(note: not honoured by ScreenCaptureKit on recent macOS) - Linux: not available; document it
Background:
- leanflutter/window_manager#215: equivalent of Electron's setContentProtection
