This is the first post in a new BlackBerry category in my blog. Having attended the “BlackBerry 10 Dev Jam” in London last week, BB10 looks very interesting – and a spiritual successor to MeeGo 1.2 Harmattan, i.e. the Nokia N9.
It’s particularly interesting as BlackBerry have created their own Qt/QML-based environment, called Cascades.
However, I’ve got an existing app, Bedside which is almost pure QML. Could I get it running? More detailed instructions will come later, but here’s how I got to where I am:
- Install the BlackBerry 10 Native SDK and developer environment.
- Create a new BlackBerry Cascades C++ project, although we’re going to use it for “plain” Qt (as described in this Chinese blog post).
- Ensure you add
bar-descriptor.xml. - Copy
qmlapplicationviewer.{cpp,h}from the existing project intoAPP/src/. - Put your QML resources in
APP/assets/(note you can’t useasset://...URLs within the QML files, as you can with Cascades). - Replace
main.cppwith a simplified version from your other project, for example:
#include
#include
#include "qmlapplicationviewer.h"
int main(int argc, char **argv) {
QApplication app(argc, argv);
QmlApplicationViewer viewer;
viewer.setMainQmlFile("app/native/assets/main.qml");
viewer.showFullScreen();
return app.exec();
}
In particular, note the path to the main-QML-file.
And here’s the initial version of Bedside (with no screensaver interaction yet) running on the BlackBerry 10 Dev Alpha:
