Electron-Window-Position

Easy and intuitive window positioning for electron browser windows.

When opening an Electron BrowserWindow one have to define an position or use the default, which centers the window over all screens.
On some systems the default centering won't open the window on your current screen, e.g. the window could open on a monitor which is switched off.

This package detects on which screen the users mouse is and centers the window on that screen. Or opens it in the top left corner of that screen.

Installation

npm install electron-window-position --save

Usage

const electron = require('electron');
const WindowPosition = require( 'electron-window-position' );
 
// Open window on electron.app.ready
new WindowPosition( function ( pos ){
  mainWindow = new electron.BrowserWindow({
      x: pos.x, 
      y: pos.y,
      width: 300,
      height: 300,
      show: true,
      resizable: false
  });
});

const electron = require('electron');
const WindowPosition = require( 'electron-window-position' );
 
// Get position for centered window
var position = new WindowPosition();
try{
  var pos = position.getActiveScreenCenter(300,300);
  
  mainWindow = new electron.BrowserWindow({
      x: pos.x, 
      y: pos.y,
      width: 300,
      height: 300,
      show: true,
      resizable: false
  });
} catch (e) {
    // electron.app not ready
}
