electron-overlay-window
Library for creating overlay windows, intended to complement Electron.
Responsible for:
- Finding target window by title
- Making overlay window a child of target
- Keeping position and size of overlay window with target in sync
- Emits lifecycle events
Important notes:
- You can initialize library only once (overlay window must never die, and title by which target window is searched cannot be changed)
- You can have only one overlay window
- Found target window remains "valid" even if its title has changed
- Correct behavior is guaranteed only for top-level windows (A top-level window is a window that is not a child window, or has no parent window (which is the same as having the "desktop window" as a parent))
- Windows: target window must have the same or lower privilege level than overlay window
- X11: library relies on EWHM, more specifically
_NET_ACTIVE_WINDOW
,_NET_WM_STATE_FULLSCREEN
,_NET_WM_NAME
Supported backends:
- Windows (7 - 10)
- Linux (X11)
Recommended dev utils
- Windows: AccEvent (accevent.exe) and Inspect Object (inspect.exe) from Windows SDK
- X11: xwininfo, xprop, xev
