Qt Creator

Stable plugin architecture

Many interesting customer projects

Develop hybrid applications and UIs

Emulator that enables desktop and device development on the same machine.

2014 The Qt Company

28

And where are we headed?

Always forwards!

New mobile OSes come and go every year.

The Desktop and Mobile is seemingly merging

Industrial applications look like app store games

Continue to drive the state of the art UI development

Every screen wants to have the same content and UX as a mobile

No one screen size or platform suffers

Better Life Cycle Management

Historically, shipping a Qt application has been a complicated task

Goals 1. Simplify dependencies and packaging steps for Qt 5 applications (Framework tasks) 2. Provide wizard / automation tools to further improve workflow (Tooling tasks)

Distribution Channel Independent

As one potential distribution method the Qt Installer Framework will be integrated into Qt Creator

Develop Package Distribute Design
