quick-widgets is an application to facilitate creating and deploying home screen widgets.

see thread on talk

Contents

[edit] Features

  • run Qt Quick applications as home widgets
  • suspend widget when not on current home screen
  • access to system calls in QML (wrapping QProcess)
  • fix widget to size or let content determine the size
  • restore after reboot/crash
  • rotate with landscape/portrait orientation
  • absolutely no compilation/building required!

[edit] Wish list

  • base widgets
  • more event bindings directly in qml
