Cascades UI vs. Qt UI?… What the heck?! December 14, 2012

We do like QtQuick2! But… . Qt 5 won’t be ready in time for BlackBerry 10 . QML only . No set of native controls . UI thread can block rendering . We already have TAT’s Cascades engine

Qt Developer Days 2012 14 Cascades UI vs Qt UI? . Cascades is native BlackBerry 10 UI framework . Allows writing apps in C++ or/and QML in a Qt way! . It is based on Qt but… . Has an own client-server scenegraph-based rendering backend (does not use Qt for this) . You have to decide upfront which UI framework to use . But!! You can use non-UI BlackBerry 10 platform API in Qt UI apps . More about Cascades and platform API: https://developer.blackberry.com/cascades/documentation Qt Developer Days 2012 15 Qt on BlackBerry 10, again
