[chimera-dev] binding handlers to SortableTable checkboxes

[Jan Kosinski]

Ah, right! I followed your suggestion and got it working nicely with python property decorator. Much more elegant and modular than the subclassing solution, thanks! My data is a list of custom objects, so problem with adjusting that.

For instance, if your data is an attribute then change it into a property so that you can perform additional actions when the attribute is changed.  Again, I don’t know what your data is or what level of control you have over it, so I’m offering suggestions in the dark here.
