Transitions The Qt Project (open governance) Qt5 / KDE Frameworks 5
Frameworks 5 Monolithic > Modular
Whatcom Sehome Bellingham Fairhaven
Incremental Consolidation
Frameworks 5 Each function is distinct Move KDE capabilities to Qt Mostly transparent to users
Soft Stuff
As important as technical Easy to understand and work on More people can contribute Shared responsibility Available to all Qt developers Recruiting value
Tiers
Refer to link-time dependencies Tier 1 depend only on Qt official frameworks or system libraries Tiers 2 and 3 can depend on same level or lower tiers
Types
Functional Qt Addons
no runtime dependencies; drop-in functionality KArchive—file compression/extraction Threadweaver—multi-threaded code KPlotting—simple plotting KConfig—configuration settings
Types
Integration Qt Addons
optional runtime dependencies; integrate with underlying OS/Platform
Integration Qt Addons
Sonnet
spell checking, grammar, automatic language detection, multilingual tools, dictionary, thesaurus Solid hardware detection and information storage devices and volumes, CPU, battery status, power management, network status and interfaces, Bluetooth
Solutions
Types
mandatory runtime dependencies; e.g., scalability, resource sharing KIO—local & remote file browsing and editing KService—advanced features for plugins (user's preferred PDF viewer)
