Cannot get chrome.window instance with chrome.app.window.get

Question

I'm trying the following code when i click on a button:

chrome.app.window.create('sample.html', {
        id: 'test',
        'bounds': {
          'width': 200,
          'height': 200
        },
        'resizable' : false,
        'frame': { type: "none" }
    })
    console.debug(chrome.app.window.getAll())
    var windowcreated = chrome.app.window.get('test');
    windowcreated.innerBounds.height = 50;
    windowcreated.innerBounds.width = 200;

But here's what the console says:

Uncaught TypeError: Cannot read property 'innerBounds' of null

And the debug of getAll() only returns my original window created in background.js. I don't get what i'm doing wrong...

chrome.app.window.create() is asynchronous.

By the time your execution reaches chrome.app.window.get('test'), that window does not exist yet.

You need to move your logic in the callback of chrome.app.window.create:

chrome.app.window.create('sample.html', {
    id: 'test',
    'bounds': {
      'width': 200,
      'height': 200
    },
    'resizable' : false,
    'frame': { type: "none" }
}, function(createdWindow) {
  // Do stuff here, and no need for get()
  createdWindow.innerBounds.height = 50;
  createdWindow.innerBounds.width = 200;
});

Thanks man ! I will do that :) Didn't know it was asynchronous. – Devz Jun 26 '15 at 15:03
Most of the Chrome API is asynchronous. Exceptions (like `get()` here) are rare. – Xan Jun 26 '15 at 15:05
