Moksha - HTML5/CSS with Snowshoe/Qt5.0.1

Qt5.0.1 was released recently, and Qt5.0.1, and its Webkit2 build are now available for testing on TI platforms. To show-case the capability of HTML5 based Data visualisation on TI platforms with Webkit2, a simple CSS layout has been created to be readily used for evaluation in compliant Browsers.

Snowshoe, a Qt5 QML based browser has been used for this experiment. CSS, SVG, and Webkit specific optimisations are used. AM335x EVM was the HW platform used.

Video snapshot of the HTML5 capabilities, using the Moksha layout is available at below link:
