• Stacked Menu: Titlebar stacked above menu bar.
• Vertical Menu: All menu items moved into a vertical submenu.

Usage

Electron Browser SetUp

mainWindow = new BrowserWindow({
  width: 1024,
  height: 728,
  minWidth: 600, // set a min width!
  minHeight: 300, // and a min height!
  // Remove the window frame from windows applications
  frame: false,
  // Hide the titlebar from MacOS applications while keeping the stop lights
  titleBarStyle: 'hidden',
});

React App SetUp

import React from 'react'
import icon from 'path/to/icon.png';
import menu from 'path/to/menu';
import { remote } from 'electron';

import TitleBar from 'frameless-titlebar'

const currentWindow = remote.getCurrentWindow();

const Example = () => {
  // manage window state, default to currentWindow maximized state
  const [maximized, setMaximized] = useState(currentWindow.isMaximized());
  // add window listeners for currentWindow
  useEffect(() => {
    const onMaximized = () => setMaximized(true);
    const onRestore = () => setMaximized(false);
    currentWindow.on("maximize", onMaximized);
    currentWindow.on("unmaximize", onRestore);
    return () => {
      currentWindow.removeListener("maximize", onMaximized);
      currentWindow.removeListener("unmaximize", onRestore);
    }
  }, []);

  // used by double click on the titlebar
  // and by the maximize control button
  const handleMaximize = () => {
    if (maximized) {
      currentWindow.restore();
    } else {
      currentWindow.maximize();
    }
  }

  return (
    <div>
      <TitleBar
        iconSrc={icon} // app icon
        currentWindow={currentWindow} // electron window instance
        platform={process.platform} // win32, darwin, linux
        menu={menu}
        theme={{
          // any theme overrides specific
          // to your application :)
        }}
        title="frameless app"
        onClose={() => currentWindow.close()}
        onMinimize={() => currentWindow.minimize()}
        onMaximize={handleMaximize}
        // when the titlebar is double clicked
        onDoubleClick={handleMaximize}
        // hide minimize windows control
        disableMinimize={false}
        // hide maximize windows control
        disableMaximize={false}
        // is the current window maximized?
        maximized={maximized}
      >
        {/* custom titlebar items */}
      </TitleBar>
    </div>
  )
}

Example of all of the overridable theme properties can be found in the example folder here

Use titlebar theme in children

import { useContext } from 'react';
import { TitlebarThemeContext } from 'frameless-titlebar';

const CustomItem = () => {
  // access all of the current theme properties in this
  // child component
  const theme = useContext(TitlebarThemeContext);
  return (
    <div style={{ height: theme.bar.height }}>
      {/* ... */}
    </div>
  )
}

const App = () => {
  return (
    <div>
      <TitleBar>
        <CustomItem>
      </TitleBar>
    </div>
  )
}

Example of a custom TitleBarButton can be seen here
