Screen size wrong (Dev Alpha)

OK - I have this

 

<meta name="viewport" content="initial-scale=1.0; target-densitydpi=device-dpi; width=device-width; height=device-height; user-scalable=no;" />

A Dev Alpha is 1280 x 768 - I trust the source of this info (BB guy)

 

Try something dumb like this...

 

alert(window.innerWidth + ' x  ' window.innerHeight);

 

I'm getting the numbers - gimme a sec...

 

Stupid password thing

 

570 x 342

 

Huh?

Re: Screen size wrong (Dev Alpha)

I don't have a dev alpha. But I can tell you on a BB10 phone it returns:

 

alert(window.innerWidth + ' x ' +  window.innerHeight);

 

768x1280

Re: Screen size wrong (Dev Alpha)

Are you using the meta?

 

I'm using similar code and getting 1/2 the numbers back

 

I may as well just strip out the viewport tag and see where that takes me

 

This is very annoying

 

I had to check with my BB guy about the size which was very embarrasing as I know the numbers to expect

Re: Screen size wrong (Dev Alpha)

Hi I had the same problem. you need to add the following:

 <script>
	var meta = document.createElement("meta");
	meta.setAttribute('name','viewport');
	meta.setAttribute('content','initial-scale='+ (1/window.devicePixelRatio) + ',user-scalable=no');
	document.getElementsByTagName('head')[0].appendChild(meta);
   </script>

Have a great day!

Re: Screen size wrong (Dev Alpha)

I had a similar problem and completely removed the meta viewport. Which worked, my bbUI.js app is running fine without viewport.
