QtCS2017 QtQuickControlsDeployment

Meeting minutes from (Qt Quick Controls) Deployment Challenges, QtCon 2017

Organizer: Nils Jeisecke Notetaker: Kai Koehne

• First user experience is bad
  • windeployqt does expect qml files in subdirectory
  • Qt Creator template puts main.qml in top level file

• Files / resources mess
  • Documentation for QQ Controls 1: "Everything is in resources"
  • windeployqt copies a lot of .qml files though
  • Also .qmlc files are copied by windeployqt

• • • Comment: All these .qml files are prob a bug in Qt Quick Controls 1 build scripts
    • Comment: We probably copy them for debugging/profiling

• Difference between static and dynamic builds
  • Static builds: .qml files for imports are put into the executable
  • Dynamic builds: single .qml files are shipped
  • This is not reflected by documentation though

• Why is Qt resource system better
  • Unified approach on all platforms
  • Code signing
  • .qmlc

• Same problems are there for Qt Quick Controls 2: QTBUG-48386

• Why is 'qmltooling' deployed by windeployqt?
  • Useful for debugging and profiling
  • There's no clear distinction though between 'deployment' to a device, and generating a final package.

• Conclusion
  • We think Qt resource system should be the way to go
  • Anhow, we miss the right people in the session to decide this. Let's try to schedule a second slot.
