and at native sdk when i am working on .qml, the options "design mode", "Horizontal Split Mode" and "Vertical Split Mode" are also not working.

Hello dinesh,

It sounds like you do not have a graphics device that supports preview mode. You need to have a reasonably modern graphics chipset with sufficient openGL support to use the live preview in Momentics. Specifics can be found in the "Cascades Builder" section at https://developer.blackberry.com/cascades/download/releasenotes/. Unfortunately, unless you upgrade your graphics card,  you will probably have to use the simulator or a device to view your UI.

Timvito, why not to elaborate a list with knowed unsupported graphic cards?  ( a wiki list make by revs, of course).

This problem is very annoying.

Hey Dinesh and blackqtcoder,

The QML preview requires a graphics card that supports 3-D acceleration and OpenGL 2.0 support., so that would be nVidia Geforce FX (5) and up, and ATi Radeon HD 2xxx series and up. More information about whether specific chipsets have opengl 2.0 support can be found at http://en.wikipedia.org/wiki/Comparison_of_Intel_graphics_processing_units.
