commit df0e5d0ca45f0c304fab0362ce7327cea0b2df5e Author: Kamran Riaz Khan krkhan@inspirated.com Date: Sat Jul 23 06:20:05 2011 +0500
Python black-magic to connect lists with liststores.
The ConfigPanel.confImportantContents is patched via Python property() in such a way that assigning lists to it automatically updates the liststore. The setter/getter is really ugly and hard to read, and serves only the purpose that the CLI portion does not need to be changed at all for this to work.
Once library/CLI/GUI is decoupled this obscure piece of dark magic shall be gone for good. --- src/gui/configPanel.py | 25 +++++++++++++++++++++++-- src/util/gtkTools.py | 7 +++++++ 2 files changed, 30 insertions(+), 2 deletions(-)
