window focus

[Anatoly Pashin]

Is there way to determine is window focused? Like Window.isFullscreen or Window.isKioskMode

i don't see anything obvious...but you could set a flag on the focus() and enter-fullscreen events.

That's what i tryed already. Focus event is fired ok, but there is problems with blur event: it's fired only when you switch between windows of your app. If you focus on any system window, blur event is not fired.

Hi Anatoly--

I came over to node-webkit from AppJS which had the properties you mention. I wrote a generic windowing script for node-webkit to mimic most of its features from the window.frame object in AppJS. For window focus, in order to catch all events, I had to watch two different places.

1 - The node-webkit window object

2 - The global javascript window object

--------------

//Window Controls

window.frame = gui.Window.get();

//Additional properties for the window frame to match AppJS' window.frame.state

window.frame.state = 'normal';

<snip>

//Manage window active state for styling...

window.frame.on('blur', function(e){window.frame.active = false; jQuery(document.body).addClass('inactive');});

window.frame.on('focus', function(e){window.frame.active = true; jQuery(document.body).removeClass('inactive');});

window.addEventListener('blur', function(e){window.frame.active = false; jQuery(document.body).addClass('inactive');});

window.addEventListener('focus', function(e){window.frame.active = true; jQuery(document.body).removeClass('inactive');});

-------------

With this, I can check window.frame.active to see if the window is focused or not. I have not done extensive testing with it, but checking as I write this post on a frameless app, the window chrome I've created with HTML/CSS is being styled appropriately for what the active/inactive state should be when switching between both system windows and windows in my app.

Ty Chris, will test soon.

I've come across a requirement for this, too. Was there overall luck with this approach?

It would be nice if node-webkit's Window API had a getter to determine focus state, instead of tracking it in javascript.

I was able to make this approach work on osx. It seems to be pretty reliable. Thanks Chris Price for figuring this out. I only use one window, so it might behave differently if you introduce multiple windows.

I made the following to keep track of my focus-state:

(coffee script example. )

window.gui = require('nw.gui')

window.win = window.gui.Window.get()

window.win.on 'focus', ->

window.is_in_focus = true

window.win.on 'blur', ->

window.is_in_focus = false
