Thoughts on BlackBerry Cascades from 2011

Flipping through an old notebook, I came across my notes on BlackBerry Cascades from BlackBerry DevCon 2011. This was half a year before the framework was released, and a good year and a half before the launch of BlackBerry 10. Since then I have become an expert at Cascades, but it is interesting to see some of my earlier thoughts.

2D and 3D

90% of UI could be lists

QML declarative UI from Qt

Asynchronous to help rendering rate

Signals to handle events

List Types – (SQL,XML,JSON)

Uses BBX IDE

QML looks nicer than C++

Beta in fall (November)

Everything in BBX is Qt

Somethings I got right, and with some others I look a little silly. For example Cascades has no support for 3D. In fact Cascades is actively bad at working in three dimensions and doesn’t even support giving z-values to elements. Also the beta wasn’t launched in November (at the time only a month away), but instead the next May. The emphasis on lists was a bit overblown. Creating 90% of an app out of lists can be true for pretty much any framework, and somewhat ironically I don’t actually use a ListView for creating the lists in most of my apps anyhow. The one thing that was apparent to me from the very beginning is that QML is far nicer than C/C++ ever was…
