Questions tagged [blackberry-cascades]

BlackBerry Cascades framework contains tools and APIs that you can use to build rich applications using Cascades libraries and Qt libraries.

The Cascades framework includes the following:

Cascades UI and platform APIs

You can use the Cascades UI APIs to create stunning interactions, while the platform APIs provide access to the underlying features of the BlackBerry Application Platform. You can use the Cascades UI and platform APIs to do almost anything you need to create great apps, including:

  • Develop your UI in C++, Qt Modeling Language (QML), or both
  • Take advantage of core UI controls, or expand on them and create your own custom controls
  • Communicate over mobile and Wi-Fi networks
  • Record and play media files
  • Store and retrieve data
  • Manage certificates and use cryptographic protocols

Cascades Builder

Cascades Builder is built into the QNX Momentics IDE and lets you design your UI using a visual interface. When you change the code that represents your UI, you can see the effects immediately in the design view.

Qt APIs

The Cascades framework is built using the Qt application framework. This architecture allows Cascades to leverage the Qt object model, event model, and threading model. The slots and signals mechanism in Qt allows for powerful and flexible inter-object communication. The Cascades framework incorporates features of fundamental Qt classes (such as QtCore, QtNetwork, QtXml, and QtSql, and others) and builds on them.
