if (event->button() == Qt::LeftButton) {
QPoint movement = event->pos() - mousePressedPosition;
int length = movement.manhattanLength();
int angle = atan2(qreal(movement.y()),qreal(movement.x()))*180/PI;
... show in Qt Creator ...

15. The Symbian security model
• Capabilities
• Encoded in the .dll or .exe
• Around 20 of them
• A calling .dll or .exe must have the same or less capabilities
• Certificates
• Digital pair of a key and a certificate that can sign a .sis file
• Examples: Self-signed, RnD Signed, Symbian Signed, Nokia Signed
• Phone
• Has a mapping between certificates and capabilites
• Self-signed usually only grants 5 capabilites
• Symbian Signed can grant many more across all Symbian devices

16. Express Signed: Why bother?
• The good
• Less prompts
• Proves the software is genuine
• Grants more capabilites
• Works on all Symbian devices
• The bad
• Costs money
• Hard to automate
