krpano - Mouse-Wheel Scrolling / Zooming Test

Functions / Fixes:

• Mouse-wheel Page scrolling fix - don't scroll the html page when scrolling / zooming inside the viewer.
• Flashplayer wmode = transparent / opaque fixes:
  • Enable mouse-wheel usage.
  • Detect mouse button releases (mouse-up) outside the viewer.
• Enable mouse-wheel usage on Mac OSX.
• Use the native Browser mouse-wheel events and wheel-delta values instead of the Flashplayer ones:
  • The Flashplayer wheel-delta values are 'integer' only and because of this, slow wheel moves (e.g. by touch-pads or continuous mouse wheels) were ignored or skipped in some browsers.
  • The Browser native events and wheel-delta values instead are much more accurate and allow the detection of any kind of mouse-wheel movement.

How it works:

• When the mouse is over a krpano viewer and the mouse-wheel will be used, then do zooming/scrolling in the krpano viewer and avoid scrolling the html page.
• Note: When testing locally / offline the Flashplayer security settings must be adapted!

Testcase:

• krpano Version: 1.0.8.15
• wmode=transparent (1.pano) and wmode=opaque (2.pano)
  
  
• Tested successfully on:
  • Windows
    • Firefox 3.6.28
    • Firefox 15.0.1
    • Chrome 21.0 (almost - see known problems)
    • Safari 5.1.7
    • Opera 12.02 (almost - see known problems)
    • IE 6, IE 7, IE 8, IE 9, IE 10
  • Mac
    • Firefox 15.0.1
    • Chrome 21.0 (almost - see known problems)
    • Safari 6.0
    • Opera 12.02 (almost - see known problems)
  
  
• Known problems / Browser limitations:
  • Opera 12.02 - mouse-button releases (mouse-up) outside the browser are not detectable when using wmode=transparent/opaque.
  • Chrome 21.0 - The embedded Flashplayer of Chrome ignores the Flashplayer security settings, so the Javascript Interface is locally always disabled. That means the mouse-wheel fixes can't work locally.

Other testcases:

• No wmode setting.
• Full windowed.
