Delegate question...

[baray98]

Guys,

I have an app that uses QTreeView and MyModel ( a subclass from QAbstractItemModel)

I have 4 columns in my modelItem and I want to let the 4th column to show true when the value of col 2 and 3 are the same and FALSE otherwise.

My plan is to populate my model with col 1 to 3 then In my view i would use a delegate on col 4 that will look at cols 2 and 3 and decide if its true or false.

Is this doable? any other advise from the experts.

example

My tree view
 
Item                Data1                  Data2                      Result
 |- a                1                        1                        TRUE   //<-- delegate
 |   |-a1            1                        2                        FALSE 
 |-b                 2                        2                        FALSE

My tree view

Item                Data1                  Data2                      Result
 |- a                1                        1                        TRUE   //<-- delegate
 |   |-a1            1                        2                        FALSE 
 |-b                 2                        2                        FALSE

To copy to clipboard, switch view to plain text mode

Is this doable?

Yes it is

But it will be better if you keep that logic in the model itself... delegates shouldnt be used for deciding what to display, rather HOW to display
