import { app, BrowserWindow, screen, globalShortcut } from "electron";

let mainWindow;

app.on("browser-window-focus", () => {
  if (!mainWindow) return;
  if (process.platform === "darwin") {
    let contents = mainWindow.webContents;
    globalShortcut.register("CommandOrControl+C", () => {
      contents.copy();
    });
    globalShortcut.register("CommandOrControl+V", () => {
      contents.paste();
    });
    globalShortcut.register("CommandOrControl+X", () => {
      contents.cut();
    });
    globalShortcut.register("CommandOrControl+A", () => {
      contents.selectAll();
    });
  }
});

app.on("browser-window-blur", () => {
  globalShortcut.unregisterAll();
});
