Column 0 is type int.
Column 1 is type "check".
Column 2 is type "choice." The possible values are: apple;banana;cantaloupe;date;eggplant;fig;grape
I have two questions.
1. I have set Column 1's Cell Mode to wxDATAVIEW_CELL_EDITABLE. However, the cell is grayed during execution. Does another flag have to be set for it to be editable? See the screen shot below.
2. I can't figure out how to initialize the values in Column 2 to anything. I can display a number in that column, but I want to display the text string corresponding to that number in the choices list. I.e. display "apple" instead of 0; display "banana" instead of 1; and so on.
What is the syntax to assign a value to a "choice" column in a wxDataViewListCtrl? See my attempts to figure out syntax in the code below.

// What is the syntax to access a specific column's choice value?

To solve this problem, I looked at the sample code in C:\wxWidgets\samples\dataview\dataview.cpp. I am using wxCrafter, though, and I don't know if I'm supposed to create a wxDataViewChoiceRenderer, or if that's done inside wxCrafter.
Thanks in advance for your help.
