Intro Creating your app Editing the UI Writing Code Packaging


What is Quickly?


  • Application templating system
  • Boiler plate
  • Commands
  • Integration with infrastructure
  • Opinionated choices
  • shell completion
  • Easy and fun

Quickly in Karmic

  • 0.2.5
  • First iteration of quickly and ubuntu-project template
  • Only one template
  • PPA support is there, but a bit brittle
  • $quickly tutorial up to date

Quickly in Lucid

  • 0.4.0
  • Second iteration with 2 or 3 templates
  • ubuntu-application, ubuntu-cli, maybe ubuntu-arcade
  • $quickly tutorial not up to date yet

Installing Quickly

  • $sudo apt-get install quickly
  • Lots of dependencies, so a slightly large download
  • Sets up lots of useful tools

Creating your app

  • 0.2.5: quickly create ubuntu-project appname
  • 0.4: * quickly create ubuntu-application appname
  • Creates a working application


  • In 0.2.5/karmic, only support for one work names
  • In 0.4.0/Lucid, support for multi-work names

Editing the UI

  • Code files and glade files linked by naming
  • automatially hooked up for you

Glade Command

  • within project directory
  • 0.2.5 $quickly glade
  • 0.4.0 $quickly design (support non-gnome templates)
  • Must use this command, project won't work otherwise

Glade Tips and Tricks

  • Fill tool-like interacton
  • Selecting in the inspector
  • layout via boxes, VBoxes and HBoxes
  • Changing position in a Box
  • pack_start, pack_end
  • Fill and expand control sizing, auto layout on window resizing
  • Border and padding control spacing
  • Use stock items when possible
  • add dialogs with the "dialog" command
    • 0.2.5: $quickly dialog dialogname
    • .4: $quickly add dialog dialogname
    • import the dialog
    • use New*Dialog()

d = New*Dialog() response = if response == gtk.RESPONSE_OK:

  • #do your stuff


  • In glade on signal tab
  • for buttons, use both clicked and activated
  • for menus, just activated
  • writing signal handlers

def handlername(self, widget, data=None):

  • #do your stuff #widget is the sender

Writing Code

  • finish_inishializing versus init()

Debugging and Testing

  • most common and easiest
  • leaves print statements in code, need to be deleted


  • won't cause debug output to be printed in normal run
  • a bit broken at the moment


  • pdb is a command line debugger, works well, but is a bit hard to use
  • there are graphical debuggers built into some IDEs


  • For sharing apps via email, or dropping a file somewhere
  • quite forgiving

setting up your app for packaging

  • add your name and email to the copyright file
  • issue license command
  • Edit * to define category
  • add author, email, description, long description to
  • $quickly package

Creating a deb

  • $quickly package
  • try it out


  • a bit less forgiving than package
  • create ssh keys as per launchpad instructions (will need for release)
  • create pgp keys as per launchpad instructions
    • Don't use a comment!
    • set DEBEMAIL and DEBFULLNAME in .bashrc, the same as what was in your gpg key
    • match gpg --list-secret-keys

export export DEBFULLNAME=Rick Spencer

  • Create a PPA
    • for 0.2.5 call it only "ppa", nothing else will work
    • 0.4.0 will allow you to choose a ppa
  • To release, you need to create a project in launchpad
  • $quickly share - puts latest in your ppa
  • $quickly release - does the same but also increments version and makes an announcement
