Company Confidential13
BossaTetrix: Gesture hack
void TetrixBoard::mouseReleaseEvent(QMouseEvent *event) { 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 ...

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
Company Confidential16
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
Company Confidential17
Express Signed: Set the UID3
• Sign up at symbiansigned.com• Free
• Reserve a UID for your application (0x2... protected range)• Free
• Edit your .pro file to use it• symbian: TARGET.UID3 = 0x2...
• Rebuild project• qmake
• make release-gcce
Company Confidential18
Express Signed: Publisher ID
• Get a PublisherID at www.trustcenter.de• Costs 200USD• Convert the .p12 to a .cer and a .key
• Sign the .sis file with the PublisherID• QT_SIS_CERTIFICATE=c:\foo\your_publisherid.cer
• QT_SIS_KEY=c:\foo\your_publisherid.key
• make sis
Company Confidential19
