Electron/Javascript: Detect when window is un/maximized

Question

I am creating an electron application with a custom window bar in place of the default Windows one. I need to know when the window is maximized or un-maximized in order to change the icon on the window bar to reflect the window's state.

Answer 1

maximize / unmaximized event is availble for browserwindow. https://github.com/electron/electron/blob/master/docs/api/browser-window.md#event-maximize

Answer 2

you can use:

const { remote } = require("electron");
var win = remote.BrowserWindow.getFocusedWindow();
if(win.isFullScreen()) {
  // your code here
}

or :

const { remote } = require("electron");
var win = remote.BrowserWindow.getFocusedWindow();
if(win.isMaximized()) {
  // your code here
}
