Here is what i want to do, see if can suggest me best way:
I have a view and a custom header with comboBox for every column.
In the comboBox there are some units(e.g kilogram,gram, pound, ...). if user change the unit, the content of that column have to be changed according to unit.
Since just the unit of data is changed i don't want to change the model. I just want to display its equivalent in desired unit.
So i thought best way to implement this is proxy. may be if i use a proxy in model i can fix the model but just change the displaying data in proxy.
Is that true?
Is there better solutions?
