Native Livecode Pinch and Zoom

[Ralph DiMola]

BR,

We got “Pinch-and-zoom” to work by adding a viewport  meta-tag into the head of our html files:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=5, minimum-scale=1, user-scalable=yes"/>

Hope this helps...

@ Ralph

as we say in HawaiI

"Oh! Ho!" What is this:

"    >I get pinch-and-zoom on both mobile platforms using the mobile browser

    >and again to make it work. 

Can you ask him what the secret is?  Pleeze!

@ Richard: Requesting engine level "zoomable" is not OT at all. It's mission critical on small devices and would take LC apps to on phones to whole "'nother" level.

There is AnimationEngine also, that can be leveraged to some extent for this same purpose. but you have get some math going on …so, right "non-trivial"

It would be great if it were easier.

    Could you file a bug about this? (And any differences in parity between 
    widget and mobileControl, for that matter!).
    
    IIRC we added:
    
       go back in widget ..
       go forward in widget ...
    
    To navigate forward / back (so the retreat command is at least catered 
    for I think). There's also:
    
       do ... in widget ... (although this was a horrendous mistake 
    syntactically which we are now realizing!)
       launch url ... in widget ...
    
    If you put 'widget' into the LiveCodeScript section of the dictionary 
    then you'll see the widget specific tailorings of normal LiveCode Script 
    syntax.
    
    Warmest Regards,
    
    Mark.
