8. Why Qt?
Cross-platform applications and services
– Hybrid development: convergence of web and native
applications
– Cross-platform software across desktops and devices
High application performance
– High performance regardless of underlying platform
– Apps must exploit platform resources to deliver
cutting-edge UI
Shorter time to market
– Delivering functionality faster, without increasing cost
– Targeting multiple languages and screen sizes

The mobility project
• What is it?
– New Qt APIs enabling cross-platform mobile application
development and service access.
• What is the value?
– Significant advantage for developers targeting mobile platforms,
such as Windows CE, S60, and Maemo in 2010.
• Significant advantage for carriers and their 3rd party content
developers
• Easier to create to applications targeting many platforms
– Reuse of code between the mobile platforms
– Bring existing Qt developers and new ideas to Nokia platforms.
– Bring Nokia developers to non-Nokia platforms.

11. The mobility project
• Service Framework
– Launch, discover, and communicate with services
– Use services natively or through a run-time language such as
Javascript
– Control access to services
• Context Framework
– Share context information between applications
• Contacts API
– Access stored contacts
– Create new contacts
• Location API
– Query current location
– API hides underlying Location source (GPS, Cell ID, etc)

12. !
The mobility project
• System Information API
– Access to platform and/or device information
– Determine status of available resources
• Bearer Management
– Manage available network connections
– Use the best available connection
• Messaging API
– Send and receive a variety of message types
• Multi-Media API
– Play and record audio/video
